Post by: LASTWOODSMAN on January 08, 2019, 01:57:16 PM
OSPREY 20"   SPORTS GLIDER   Vintage Model Company laser cut kit

     This laser cut kit is a traditionally constructed, free flight cabin sports glider.   If you like kits in boxes, this is a good box -    20 1/2"  X  5'  X  2", with good color pics of the actual finished model on the top and end.  And on the bottom  of the box is another big pic and more information, and smaller color pics of the other models in their lineup.

Some Interesting Design Features

-   a hollowed out laser cut nose block, which is the space for adding modellers clay ballast weight, to balance the model
-   dowels and elastics to hold both the main wings, and the tailplane, to the fuselage
-   map grid lettering and numbering on the plan margins
-   a  100  mm "Scale" in the "X' and "Y" axis, in order to check the accuracy of any photocopy of the plan you make
-   easy tab and slot locations for gluing the fin/rudder
-   a lot of strengtheners and stiffeners and reinforcing in the design
-   a piece of clear acetate for the windows and "trim tabs"
-   a lot of "tab and notch" construction
-   a nice handy little 32 page booklet of instructions, etc.
-   a supplied bottle of PVA glue (very nice addition)
-   piano wire for the tow hook
-   three laser cut clean balsa parts sheets, with no inked on parts numbers - a parts reference sheet is included instead
-   yellow and blue tissue is supplied -    one sheet each ~  29" X 10"  of  Yellow and Blue Tissue, and the plan ( 22" X 15" ),  were all rolled and not folded.
-   also laser cut pieces and instructions, for laminating a sanding block and adding different grit sandpaper to both sides

This should be an enjoyable,  "first glider" build.

OSPREY 20"  SPORTS GLIDER   Vintage Model Company laser cut kit

     Well,  I finally figured out   ???  all of these new foam Dave Banks Pilots I got from Sams,  and paired them up with the aircraft I bought them for.  These aircraft are at the top of my "to do list" that we all have.  One of these pilots is a civilian  1:20 scale Pilot for the  20" Osprey Glider.    Yes, it must have a "scale" pilot - no headless horsemen ...LOL  :D   The Fleet Canuck Pilot looks more WW1 than Civilian though.

And here are the three laser cut balsa parts sheets from the OSPREY kit, along with the  8 1/2" long  1/8" dowel,  a clear acetate sheet for the windscreen, and the instruction booklet open to "TEST GLIDES".

Pic #1    THREE BALSA SHEETS AND ACETATE AND DOWEL
Pic #2     DAVE BANKS PILOTS  3
Pic #3     30"  DH 60 GIPSY MOTH PILOT
Pic #4     20"  OSPREY PILOT
Pic #5     30"  STANDARD J-1 PILOTS
Pic #6     28" STEARMAN PILOTS

I think that is about it for the pre-amble - time to cut out the tiny balsa bridges with a new exacto blade, steel rule, and a cutting board, and release these laser cut parts ...   :)

However, does Sams not have Mounties???

Post by: LASTWOODSMAN on January 09, 2019, 07:14:26 PM
     Thanks vtdiy.   ::)   I fiddled a bit to get those pilot pics just right all together -  morning light through the balcony window/door, and  angled all the heads downward a bit, and rotated 30 degrees about the z axis, which gave just about the right light and angle to see the different features better.  And I used no flash on the digital camera.
     Unfortunately, Sams does not have any Mounties, LOL,  but I did see a very nice Easy Built model, Miss Canada Senior (36" I think), with a perfect profile head and bust of  'Dudley Do Right' of the Royal Canadian Mounted Police (RCMP) {Mounties}, our Federal Police Force - they "always get their man".   I guess you could always carve up his massive jaw and pilot head out of foam ...   ;D

It's going to be a classic looking glider. It looks like a very nicely cut and packaged kit, and pretty strong construction, too with those sheet sides. Will you run with a towline or use a hi-start?


Title: Re: OSPREY 20" SPORTS GLIDER Vintage Model Company laser cut kit
Post by: LASTWOODSMAN on January 10, 2019, 10:05:06 AM
     Morning vtdiy.   The kit is designed to be built as a traditionally constructed, Free Flight cabin Sports Glider -  ie   a built up balsa wood skeleton (framework), covered with a tissue skin.   Although not a "serious" sports glider model, it is capable of surprisingly long flights.  The Instruction Booklet also talks about the decline and loss of manufacturers such as FROG, KeilKraft, and Veron, and the revival of these kits which is now underway today.
     Since I will be  flying on flat grass (no hills or slopes here), I think I will be just going for short and simple flights with hand launching with a rubber band catapult, and learn about glider trimming.  No towline or highstart - not enough room in a Cricket Wicket Grounds.   The model seems to be reinforced quite well, so we will see how it handles those "cartwheel landings" -  no props or motors to worry about - just pure gliding.   Time to start cutting out the parts of this first Glider ...

The old style gliders are the prettiest planes of all, to me. As a kid I really wanted a Berkeley Sinbad, bad!

Hand launching w/ or without catapault sounds like fun!

Post by: cvasecuk on January 10, 2019, 10:39:20 AM
I'm not sure what you mean by "catapult" but this model is really only strong enough for a hi-start of a few feet of 1/8" rubber (or less) and a few yards of line. Anything more than that will pull the wings off!
Regards
Ron

     Hi Ron - thanks for the warning!   :o   I'm not sure of the proper terminology - hand held bungee launch with a length (?)  of 1/8" rubber at the end of a stick, using the "towhook" wire at the bottom of the main skid - yes   :D  I don't want to rip off the wings ... LOL
     Hi vtdiy - thanks for the "Sinbad" glider pic -  the Sinbad is a beauty and was next on the list, and it is available in 36" laser cut kit here at Retro RC here  
http://retrorc.us.com/retroemoth-1-2-1-2-1-1-2.aspx     
and a whole lot of other gliders here       There are so many nice ones to choose from.

Definitely smaller width.  My experiments last summer with 1/8" and my Osprey were really rather hair-raising.  The wings stay on OK, but you get ferocious loops on launch with anything but the slightest tension, even with packing under the trailing edge.   

I've got some 1/16" that I bought just before Xmas with both it and the Walthew MKII in mind which I'll be trying when I get that rare combination of decent-ish weather and the free time to take advantage of it.

Guys, the "family" towline glider was the Sinbad. It hung from the ceiling of every house I lived is since before I was born. I don't know where it is now, it was last seen in Thee Olde Man's studio in the Florida Keys. Lots of stuff went here and there when we moved him out. We flew the "H" out of the Sinbad. I am quite turned on by the robust, yet elegant curvy look of the cars, planes and women of that age! I like this new trajectory you are on Richard!

Hi Crabby - throw in a pic of the olde man's Sinbad glider if you have one - it's nice to hear annecdotes from the olden days -  I agree with "the robust, yet elegant curvy look of the cars, planes and women of that age!"   Take for instance, my first car, in 1971 at age 15, gasoline was 32 cents per Imperial Canadian gallon (4.54 litres), insurance only $80 per year, and drove it all year full time under my parent's name (they never drove it) -  a 1967 Chrysler Dodge Polara two door hardtop - a robust elegant boat - 318 cu in V8  -  18 to 20 mpg all the time.  :)

Balsa Sheet no 1 parts all cut out and labelled.

Heh, I was drivin' a '61 Austin Healey 3000 then that I had bought for $450. Not exactly a Vermont suitable car, with almost zero ground clearance to begin with and trying to negotiate snow covered dirt roads. I'd knock the muffler off the flexi-headpipes sometimes just driving over the curb ramp at a gas station, trying to get some of that 32 cent gas! I think I eventually sold it for $350 and got a VW beetle of similar vintage. Now Healeys are worth a fortune.

Man you are organized for this build. What a layout! Looking forward to first glue!

At my end of the towline.  'Walkin' Shoes' at the top end. 66"version of my 1955 88" original.

Actually, not much running with a good towhook position - just enough to get nose up into the breeze and then it kites to top of line.  In 84th year I'm not much into sprinting   :-)

Sorry my build is taking so long .   Laser cut sheets #2 and #3 - the parts do NOT fall out when the small bridges are cut, because the laser cut files did not work.    All you have to do is hold it up to the light to see it.    The laser cut lines did not extend far enough in to the corners of the parts, to meet up with the other laser cut lines.  Really  a hassle to have to trace every laser cut line with a steel rule, and try to meet up with the other one.   Especially all of the very small notches.   If you buy this kit - make sure they examine their laser cut sheets before they mail it to you.  This is my first laser cut VMC kit.   ??? ???

Interesting.  I had no trouble whatsoever when I built mine, nor with any other of the VMC kits I've built.  An unfortunate one-off with your kit perhaps? This sort of thing does happen with even the best manufacturers.

I concur with the Lurker as with both the VMC kits I have built had no issues with part seperation. Seems like a one off that you have clearly dealt with very easily. Think about the die crushed kits we used to have to deal to and often replace useless parts.

ZK-AUD, you could sand that sheet all the way to powder and it won't connect the cut lines. This isn't a shallow diecut.

Hello fellow modellers:

     I just got a friendly phone call from Mr. Hadi Kanan at VMC ( Vintage Model Company ).   He said that they did have a problem with the laser cut settings and that they are sending me a free replacement kit which should be here in 4 days.
    I'm very happy with their response, as it goes beyond the call for replacement sheets.
    I'm sorry about any earlier misunderstandings that were created ...   I was very excited to build this VMC OSPREY glider kit.  And now I'm looking forward to continuing with the same excitement!

The important thing, always, is doing the right thing in the end and trying to solve problems. I'd buy a VMC kit and I'm glad to build models along side of you in this forum, LASTWOODSMAN.

     Looks like I am totally scrapping the first kit   :(   and starting over with the new replacement glider kit.
     I think I found what might be part of the problem with the laser cutting of balsa parts sheet #2  and sheet #3,  of the original first kit.  
     These two sheets were both thicker than sheet #1 ( 1/16" ),  by  about  13.6%  and  18.2%  respectively   ???  , which may have contributed to  why the laser cut did not go through.   All three parts sheets, of the newer kit, have the exact same sheet thickness of 0.0665" , and the laser cut is perfect.
     And since there is tab and notch construction in this kit, oversize parts   :P  will not fit.   Therefor, we will be starting over using the whole new replacement kit.    Reports coming up ...   :)

OSPREY 20"   SPORTS GLIDER   Vintage Model Company laser cut kit

     The parts are now prepared.   All of the laser cut parts "fell out",  when the tiny balsa bridges were cut.

     The laser cut parts' edges were hardly burned at all.  There was no black charring, and very little discoloration.  Very light, very short, sanding swipes, by Mandrake and Bloodroot, brought all of the balsa parts down to their lowest common denominator - clean white balsa.

Pic #1     1319    Down to the last of the laser cut parts on the third sheet.

Pic #2     1327     Mandrake and Bloodroot "go all out",  and even lightly sand the laser cut edges.

Pic #3     1324     All of the parts are now cut out, the edges of the parts are sanded to white balsa,  and all of the parts are now labelled.

The video clip was an interesting look back into history.
I liked the comment halfway through when 'that flying these gliders is regarded by some as harder than flying REAL aeroplanes". I guess that means they don't have real crashes :)

     Work continues on the outer wing panels.
     The center section of the wing is now done.  One of the gussets had a false glue joint on one surface.  Repeated hot water from a small brush loosened the white glue, and M and B reglued the gusset  -   no weak point any more ... ( for that cartwheel landing   :(  ).
     M & B examine the shape of the strong center spar W4, that has an angled end from the last rib, down to the wing tip piece W3, already built in.

OSPREY  20"   SPORTS GLIDER   Vintage Model Company laser cut kit

      Everything in this kit seems to be tab and notch in both LE and TE and the ribs -   really sturdy tab and notch construction.

Pic #1     1346     All of the ribs and spars were blocked up and test fit.    Then they were double white glued and pinned flat to the building board, except the inner ribs.   The ribs were held in place by long balsa planks bent under pressure by a round head pin in each end.

Pic #2     1350      I noticed that I missed four small gussets  ???  in the wing center section -  added now.   The inner and outer ribs on the outer wing sections are now glued in place, and gussets are added.   The parts board is getting smaller.   :D

Pic #3     1352     This is a view of the single spar added to each outer wing panel, and it is also pinned down flat to the board, with those bent balsa planks.

Pic #4     1355    After letting the "double" white glue dry overnight, Mandrake and Bloodroot carefully remove, using the "sharpened" flat butter knife,  the wing sections from the board, to see if all of the gussets and LEs and TEs and ribs,  to see if they actually glued flat on the bottom.

Pic #5     1359     Success -  they were all flat on the bottom!    M and B now lightly sand the bottoms of the wing sections with 150 grit sandpaper.

Pic #6     1358     Here is the finished underside.   These laser cut parts all fit together wonderfully,  they are all flush and even, with solid "double white glued" joints on all mating surfaces.   These tab and notch joints do seem to be very much stronger than a butt glued joint.   I always like to try to get the framework as good as possible -   thereby not qualifying as an excuse for a bad tissue covering job ...

2nd post of the day

     Before starting on the fuselage, Mandrake and Bloodroot decided to finish all of the final sanding and fitting, of the completed framed parts, built so far.     All the lightly laser cut edges were easily sanded with a couple of light swipes.   All of the balsa is now very nice and white and clean, which leaves open the option of wood staining the framework before covering it with tissue.   I plan on gluing the tissue to all rib edges, and all surfaces, using "white glue" ( thinned to 70% glue and 30% water ).    Mandrake and Bloodroot even sanded the inside edges of the fuse cutouts, using round steel files.
     The wing panels are now test fitted and sanded for a very close alignment of the Leading Edge and Trailing Edge, and the mating rib faces, using the two 32 mm balsa blocks to set the test dihedral.   A tiny bit face of balsa was sanded off of the outside of the outer ribs of the center wing,  in order to get the dihedral angle correct, when holding the ribs together of the outer wing panels, to/with the ribs on the center section.   It all really fits well.   With all of the ice and bad weather outside, it was a perfect day for some liesurely, exacting sanding, whilst listening to some calm peaceful and relaxing, "meditation relaxation and study" Celtic Harp and Flute music.    here - one hour

     Time to work on the laminations for the NOSE BLOCK, the NOSE PLUG, and the FRONT END FUSE FORMERS.    I plan to use the  fifteen sixty-fourth  15/64"  drill bit,  and the  3/8" square Balsa Stick to align the holes when gluing the laminations on top of each other, and use clear Scotch tape and waxed paper to prevent the wrong things from being glued, and make a plate to hold the drill bit and Balsa Stick, while the parts are pinned down tight to dry.

Pic #1     1405    The three sets of lamination parts are laid out.  Now to figure out a mounting plate to hold the drill bit and square Balsa Stick mounting shafts.

Pic #2     1407     I found a good reason to pull out some sharp wood carving chisels -  to gouge out a  3/8" square "Mortise" hole in the mounting plank.  What a pleasure to actually chisel off some nice wood chips instead of always sanding.   :)

Pic #3     1410     The drill bit and square balsa stick  are now mounted on plates and pinned down and squared up, ready for stacking and gluing.   One of the carving chisels is a right angle square cutting edge for getting into those corners.

     Hi John - we are going to use the 'Combination Wing' pattern, and here it is colored up with a small color change to see what it looked like.  I would like to print the wing pattern onto the tissue, but my printer is fried and it has no ink anyway.  :-\ 
     We thought we would try tissue over tissue -  using a base white tissue, and cutting out and gluing the little colored tissue panel pieces, and glue these on top of the white tissue pre shrunk, and then ink in the black feather lines after drying.   Waaaay too hard.    >:(

Pic #1     1457     Mandrake and Bloodroot traced the other wing on the window, by folding the paper down the middle, over.  The "combination" wing is colored in,  switching the orange for the light brown color, and vice versa.

Pic #2     1462     M and B tried in vain to cut out the individual colored tissue pieces (upper right), to no avail .... and takes way too long ...    :P

     Then we thought of turning it into a "paper model" by way of just cutting out the colored wings on the printer paper and just glueing that to the wing frames.    But the wing frame weighs only   2.50 grams,  and to cover one side of the wing with printer paper weighs  2.12 grams.   :o  :o

     Oh - and I have an open flight theory question about the lift from the primaries that are separated in pic #2,   WING SHAPES,  in reply #55 above,  The "Passive Soaring Wings"   -   'long primary feathers with long gaps in between.   These slots help the bird take advantage of columns of rising hot air, allowing it to soar'.   How do these slots enable lift ?   ???

     Hi Dan - thanks for the comment.   Unfortunately, the color design may only just look good on paper - and is probably just wishful thinking - getting it on the glider is another thing ...    ???   I am open to suggestions for this color scheme,  in light of a lack of a working printer.   Maybe just a simpler design, and of course, lose those cluttering feather quill black lines...  we are also contemplating orange on top of the fuse, to match and blend in with, the secondary feather coverts (little feathers) ...

Richard I was wondering if you had considered colouring the tissue directly with the markers or even crayons? You could use your sketches under the tissue as a guide. The tissue would need to be taped down firmly and the colours applied very gently - perhaps on the inside of the covering?
Might be worth a small test.

'long primary feathers with long gaps in between.   These slots help the bird take advantage of columns of rising hot air, allowing it to soar'.   How do these slots enable lift ?

I think the action of the slots would help to keep the airflow on the top of the wing attached by injecting some high energy air from the bottom of the wing to the top, via the slots. The location, size and shape of the slots would be critical. Thus the overall drag of the wing would be reduced - particularly at high angles of attack which would be higher than normal as well with a higher corresponding lift coefffecient, and the climb rate increased. Even if they remained open the slots would have little effect at high speed.
Modellers have tried variations on this using small holes on the bottom of the wing and exit holes towards the rear on the top with tissue covered wings.
However as the location is critical and airfoil dependent - most have stayed with either forward placed turbulators or a series of small turbulators as specified by Martin Presnell which he named invigorators.

     Thanks so much for the tip John.    :)    I placed a sheet of  0.005"  (five thou )  clear plastic sheet down over the wing tracing, and then I put on a white sheet of tissue on top of that.
     I started tracing with the thick pen on the leading edge only and the ink was really running from the edges of the thick line of ink.   Then we switched to the 0.5 mm Studio Gel pen for a much cleaner thinner line.  Then I got out the four colored markers and filled in the areas.   The ink ran through to the bottom of the tissue.  You can see the smudges left on the clear plastic sheet, that will not wipe off with bathroom tissue and water.   As I was coloring with the marker, I could see the ink from the marker pooling under the tissue and on top of the clear plastic, and running around.  There are also many wrinkles in the tissue, and I am wondering how it will shrink and/or run the ink when I spray mist it to dry.   
     It looks very promising though.  I just need to do more testing.   I must also buy three more light, medium, and brown markers.   Of course they will run out anytime now ...   :-\
Here are the two latest pics.

     The only way to stop the ink from flowing through the tissue into a puddle, is to have a sheet of printer paper (not clear plastic), on the other side to absorb the excess ink.
      The color scheme is working out OK.   I just have to decide on a few details more, and make two good, top and bottom, colored tissue patterns for the wing.

Pic #1     1468     The two colored tissue practise Wing panels at the top are done.  The one on the left has got the thicker runnier ink, and the one on the right has the thin ink.   The top of the wing,  at the center fuse  section, will be orange also. 

Pic #2     1467     Here is the wing frames sitting on top of the two painted tissue panels.

Pic #3     1469     Here is what it looks like with both tissue panels on the top and bottom of the fight wing frame.

Pic #4     1471     This is the test fit and look, with both tissue panels held up to the light.    The prime objective now, this spring, is to get a good close up pic of this  20"  OSPREY Glider, in the air, with the sun shining through.    It is time to figure out the tail color pattern also,  and the pilot mount ...   :)

     Hi John -  yes, that is what I am leaning towards on the fuse sides and bottom - tan or light brown tissue.  The top of the fuse will be the same white tissue painted orange with the ink marker, and the fin/rudder a slightly darker orange tissue, and the stab will be golden rod yellow tissue with some sort of  feathering for the narrow tail.
     All of the framework, especially in the cockpit area, will be stained a suitable color.  The nose block may have alternating dark and light stain laminations ...

OSPREY  20"   SPORTS GLIDER  Vintage Model Company laser cut kit

     Thanks for the nice comment Dave.  I'm starting to like the color and design more and more myself.   :D
     Trying to get the color scheme just right was a lot of work.    ???  Changes were made along the way, and I think the alula and scapular (tertial?) feathers are now not so terrible looking.   We were comparing thin and thick outlines and colored a few up to see what they look like.

Pic #1     1475     This is the setup for tracing the final outlines on the wing tissue panels.   Here the white tissue (combination wing) is stretched and taped out FLAT and TIGHT (just like OZPAF John suggested),  over the wing plan.   There are three more tissue panels in the roll waiting for thin black ink tracing.

Pic #2     1477     Mandrake "Good job Blood".  Freshly traced  0.5 mm thin wing outline, right over the colored "combination" paper wing.   M and B used ample tissue for this job.   The blue section outline of the wing is extended out  3/8" , in order for the blue color tissue to wrap around the wing edges to meet top and bottom, and cut off the excess of course.   And there is lots of extra white tissue now to work with to pull tight when gluing the tissue to the frame and every rib.

Pic #3     1479     Here Mandrake and Bloodroot have removed the freshly traced wing and check for major ink blobs - looks pretty good.

Pic #4     1481     The new panel is upper left, and it has been colored,  and, as an experiment, its thin outline was traced over with the thicker Penmark ink, clearly more visible.   The old right side wing (without all of the extra blue and the extra white tissue),  has the thin black outline for comparison.   I think the thick outline looks better.   Three more final design patterns are now traced onto white tissue.   We need one for the top and bottom of each wing.   Note the colored "ink blotter" wing pattern after the tissue was removed from on top.

Pic #5     1488     Here the two tissue panels are overlaid with the wing frame.

Pic #6     1485     Here is a pic from underneath from under the table (carpet level),  up through the clear glass of my building table (that is an air conditioner at the top of the wall) , and up into  the tissue with the balsa behind,  all "sunlit" from above with two table lamps, which shows the different outline thicknesses, and shows somewhat what it should look like in the air.  For the choice of ink thickness for the outline of the wing - either the thick black line or the thin black line - it sure looks like the thicker black ink outline gives a sharper contrast with the sky blue tissue.   I will just have to tightly re-tape the tissue panels down again with masking tape - I left a lot of extra tissue to work with - and thicken the black outline with the thicker pen, and then color them, using a clean sheet of white printer paper, as and ink blotter, to prevent the ink from running.    

The ink blotter paper backup sheet can be seen in pic #4   1481 , at the lower left, and how it soaks up all of the extra ink bleeds.   I call this my "abstract Picasso" wing pattern.

Hi John.  Thanks for that.  It took a lot of fiddling with good light etc, to get that last pic - it sure does make the wing look long.    We will have to wait and see though, what it looks like with two identical colored tissue panels, top and bottom, with the "good" light shining through them ...

     Mandrake and Bloodroot are told to come up with a couple of designs for the stab,  but also to try to match the wing design.

Pic #1     1495     Bloodroot is drawing a design in pencil.

Your "fine-feathered" designs look good!  Are you using Esaki tissue?  Was also curious what you'll use to seal the tissue, ie Krylon, or dope or?  I'm doing a similar set of experiments for 2 no-cal models, where I have used a combination of permanent and "not so permanent" markers, and colored pencils.  I think a light dusting of white Design Master "floral spray" on the backside of white Esaki tissue is all I will do, after I draw the color markings on the fuselage tissue. (Wings and tail are simply all white with Ultra fine black Sharpie pen used for control surface outlines).  I've also tested my glue stick and PVA/white glue for bonding tissue to the structure outlines, with no "bleed" or compatibility problems. 

I preshrink the tissue first, laying the wetted tissue on a dishrack/drainboard to air-dry.  Seems to do better, when "unrestrained".  Attaching to a picture frame seems to limit the amount of shrinkage the tissue undergoes.  Then I iron the tissue to smooth it out, before applying the markings.

 
Anyway, watching this with interest!

     Hi Indoor flyer.  Thanks for the nice reply.  :)  Yes, this design feathering and outlining and coloring really is an experiment, as I have not tried this approach before.  I am worried about the ink color "bleed"  when I try to shrink and seal the tissue.  I think it is Esaki white tissue that I am using to ink up these designs on.  It came from a Sig  22"   'Cabinaire'  laser kit that I used a different color scheme on.   
      The only thing I have ever used for sealing shrunken tissue is Krylon Clear Gloss ( after shrinking with water ), a couple of light coats of which, really brings out the color and clear look transparency of the tissue.    I thought I was going to glue the finished, colored tissue panels, to the ribs and all balsa, stringers etc, using only a small thinned bead of  White Glue ( 70%  white glue  30%  water ),  and try to pull the tissue really tight and pin it down as best I can, let it dry, and then figure out what to do as far as shrinking and sealing.   I am open to any suggestions.   I think the colored Marker ink I am using is water soluble, which opens a cans of worms  ...

Good am lastwood, of course you are gonna do a bench test, and you really ought to be using permanent makers like the sharpies, but since you are using water solubles you would be better off shrinking with 91% alcohol than plain water. Beware to keep the cap tight as the more air that gets introduced into the alcohol, the water content increases. Would it be a deal breaker to do the art over with permanent makers? Good luck! Great looking model!

     Hi Crabby - thanks for the tips and nice comment.   I do have one wing tissue panel outlined and colored up that was a spare, so I will cut it into half or thirds and do the bench test experiment as you say, and see if and how this ink bleeds and seals.   The "Rubbing Alcohol" I have here is  70% Ethyl alcohol (Ethanol) and  30% water.
      I remember looking specifically for different colored brown markers way back, and I found the brown colors were very hard to find - these are the only ones I found and they are not permanent I think.   This color scheme turned out to be way more tedious and exacting work, trying to make those thin lines and tracing, than I thought it was going to be.   I had better just try with this for now and see how it turns out.
      Latest pics coming right up!   ;D

OSPREY 20"  SPORTS GLIDER   Vintage Model Company laser cut kit

Pic #1     1511     The tissue for the stabilizer has been stretched out, taped down tight, and it has been inked in with thick outlines, and thinner inside lines.

Pic #2     1512     At the top are two stab tissue panels all inked up, and one is also colored.

Pic #3     1514     The second stab tissue panel is taped up tight and ready to color.   This is the correct scale distance between the stab and the wings.

Pic #4     1516     Here both stab tissue panels are done.  I finally discovered how to spread the blue ink horizontally (east to west),  on the lower stab panel, without the thick overlap of ink strokes.

Pic #5     1517     More abstract Picasso art   :-\  on the "ink blotter" backing printer sheet.

Pic #6     1518     This is what is done so far.  There are two old practice wings at the top left.   The two stab panels are done, only one of the four wing panels is colored, and all four of the wing panels need the thick black outline inking.  Lots of work yet    ???  ???   for Mandrake and Bloodroot   ;D  , that is ...

    We got started on finishing the tissue pattern coloring and outlining ...

     All things really must be taped down flat, with a clean ink blotter sheet in behind ...

     This wing just needs the thicker outline, and the blue has been filled in on the white edges, where the rib location marks are.   This thicker black inking on the outline is hard to do because you have to do long, even, relatively slow, strokes with the pen, without stopping.  If you stop and try to start up again at the same spot, you WILL have an inkblot.

Hi Lincoln.  Thanks for the link -  that scary eagle head is pretty scary, what with the teeth inside the beak.   :o   Those are pretty good color templates.

Hi Indoorflyer.   Here is three pics of these 20" Osprey glider feathered templates.   Let me know if they are OK to use.   I always drew the left half first, folded it over in the middle centerline, and then traced it on the window, to get the exact same shape of the feathers for the opposite right side.  The rib locations are all marked.  Any questions, please ask away ...

     There does not appear to be any running  of the paint colors or the black line inking.   Maybe that "ink blotter" backing sheet, really sponged up, and soaked up, all of the excess marker paint color.   Maybe I should have tried a much larger test piece of tissue ?   ???

    Well, we are in a deep freeze here again, so time for more research into gliders and canopies and pilots and control panels.
     It is interesting how the pilots'  legs are crammed into the nose of the cockpits of modern gliders.
     I also found some really good Glider Pilots (although too large for a  1:20  scale glider), but these pilots -  "Roger's Pilots"  -  have great color schemes, and great realism.   Here at  http://rogers-pilots.co.uk/pilots.html

   Hi Richard
                  Great work you're doing here, You probably have it sorted by now but I have posted a photo of an Instrument Panel from a  Grunau Baby IIb, while the instruments are German I'm sure it would suit your model. While the panel is a reproduction the instruments are original. Hope it is of some use.

     Hi Dave.  Thanks for the encouragement and that good pic.   :)   I think I will try drawing the instruments (now that I sort of have the hang of it ),  on that pic you posted of the early instrument panel of a Granau glider.   Would there also be a Magnetic Compass somewhere else in the cockpit of the Granau?
     Here is a two page (two pics),  complete (?),   list of sailplanes/gliders by country from 1920 to 1945.   This list is really handy for a guy like me, just learning about Vintage gliders and sailplanes.

     Well, the hardest, and most time consuming part, is finally done.   :P    I found some old orange and blue markers and finally finished up the fifth wing, cleared the building board, and laid out the tissue to see what it looks like.

Pic #1     1573     On this last wing, the orange is too bright.   :-\

Pic #2     1574     Pic of all of the wrinkled up,  finished tissue.

Pic #3      1575     Framework is laid over the tissue.

Pic #4     1579     A bit of orange tissue is added to the fuse front, and the nose block.   Pilot for comparison also.

Pic #5     1581     Framework is removed, and now it is starting to look like a color scheme coming together ...  looks more like a Flying Fish than a Sea Gull ...   :D

GLIDER PILOT PAINTING  1/20  scale

     Today was a nice liesurely day spent trying to get the pilot color scheme just right,  and painted  out ahead of time, before even starting on that nicely detailed, little Dave Banks Pilot bust/figure.   Figuring out the color scheme is the hard part -  the painting is then the easy part.  I must get this done before I glue the fuselage together, so I can figure out the pilot seat.

Pic #1     1616     Started to figure out the Pilot colors, so that he matches the glider color scheme.

Pic #2     1617     Close up of the list of colors to choose from, and labelling of the diagram first.

pic #3     1619     Full bench view,   and what a glider pilot looks like on the screen monitor.

Pic #4     1620    The middle pilot has the latest color scheme.

Pic #5     1621     Closeup of the middle Pilot color.  I still have to get the right amount of blue color into the seat belt harness buckle, to make it look more metallic,  or just leave it light gray.  Also the bronze of the shoulder patches is the wrong color ...

Pic #6     GLIDER  1908  TO  1945   I would like to model this one some day.  I don't know enough about the gliders yet, to properly ID this one.   Anyone ?

GLIDER PILOT PAINTING  1/20  scale

    The Pilot is all painted up.   I do need to get some fine brushes.  There is such fine detail - realistic creases and folds in the clothing -  in this foam Pilot, you can really see it coming to life as soon as you start painting it.   And a good old fashioned wave of the hair parted on the side of that youth pilot.   Wait a minute -  that is how all the kids do it now - clean cut, tapered cuts,  etc ...

Pic #1     1630     He looks like the guy in the middle.
Pic #2     1623     Closeup.
Pic #3     1626     Outside front.

Pic #5     1633     The weight of the painted pilot is  0.70   grams.   The latest mock up gages are in blue.
Pic #6     CONDOR

     It is now time to work on the mag compass mock up and finish off the other gages and the instrument panel.    These are tough to detail by hand when the gages are that small.   An 'out of focus',  little smudge of pencil lead, will have to do for a small number.

Richard, I'm embarrassed to say what I've been flying indoors -- basically a $25 Ebay RTF. Well also, a more interesting balsa and (mylar?) R/C double size version of a Delta Dart built by a friend. He calls it the "Servonaught" because it uses old Airhogs 27Mhz guts and motors to steer with. Not just the usual differential twin thrust, but also the motors are mounted on a pivoting flybar, and that has tiny lines going back to the rudder. So you get both differential thrust AND rudder. I think the whole thing weighs about 20 grams, not sure. He's a dyed in the wool FF rubber guy, so I'm his ghost pilot for very occasional R/C excursions.

I've been flying more outdoors -- built a Horten-ish flat prop in slot flying wing, designed by GPW. It originally had fins, but I flew it that way for awhile, and then tried what I call a "stepped elevon" and snipped off the fins. It still flies fine without them, and no actual washout.

I also built a slightly enlarged R/C version of a Scientific C/L Thunderbird. That's been maidened, but is not in good trim yet.

Anyway, back to your Osprey! Pilot looks very blonde. Well, more power to him, he'll be gray some day like the rest of us!
