Stupendous job on the fuselage Tom...I definitely like the lost foam construction. Great idea on the larger opening/nose plug.  This is coming together very nicely for you!!!

After seeing Tom's fuselage I know I prefer the keel and former construction to the box and former style.  Had a challenge with the box construction but finally got it to go together inverted on it's back.  Hope to add the formers tomorrow!

Great work Sky9 and Tom!!! Glad to see everyone is progressing nicely. Sky9, here are a few tips (via pictures) on the build from here out.  

Picture 1: Slice the 1/16" triangle sheet wood that hangs under the bottom longeron and glue it to F5B as shown in the picture.  

Picture 2: I chose to square up the tops of formers F6 and F7 to transition from a trapezoid shape to an egg shape which is a bit more accurate than my first attempts.

Picture 3: Here is another idea if your rudder has a little more beef to its base, like mine. I added a couple of light 1/16th square sticks to the side of the vertical keel to increase the surface for gluing. Because the rudder supports the stab, I thought it would be smart to beef up the rudder/base to handle impacts.

These are all just recommendations based on how I approach this sort of stuff.  You are free to create your own solution.  But please share it. I have been building models my whole life, but I am still learning better ways to build models.

Thanks,

Balsabug

Do any of you guys remember this build from the early days of Small Flying Arts? I was looking through some old files and found this picture. I need to pull that bird out again and see if I can fix her up. That plane flew really well.

The second picture (P-13) was built about 10 years ago.  Flew great once I sorted out the props. Still have that one in a box somewhere too.

I have to say I still love the oddballs most -

Yes .... remember them quite well  Smiley

BTW. re. Skylake's request for a DXF or DWG file. I perfectly understand if you would not want to release this .... if so, just a 'heads up' that the PDF is 'editable' so can be reverted to a CAD file quite easily.

Following Bug's lead, I "squared up" the aft end of the cockpit area and a little bit of the cowling leading into the front windscreen. The appropriate stringers were doubled up and sanded to fair in with the fuselage and balsa fill pieces were put in at the ends.

Wow you guys are killing me.
I'm trying very hard to finish (clear the building board) so I can start on the BF 109. Every time I see a new photo I run out to garage and glue on some more pieces to the projects already started. Everyone's postings are great motivators, thank you. My list of "Want to build" is changing almost daily thanks to hearing about all of the other projects people have going on. Since it was brought up, this kit is within my top ten to build.

Hoping to start building the 109 soon.

Hi there Skylake Models...

Sorry that I have not responded to your question until now, my fault as I just forgot to do so...

I do not wish to relinquish my .DWG/.DXF files as there is always to possibility that I will add them to my list of future offerings when I get my cottage model business up and running in earnest in the near future... Smiley

Have a great day,  Keith

Hi BG,
It was handed to me by John Hutchison of Scale Staffel. I believe the story goes like this. A bunch of member had gone to Geneoso and had watched this model fly. The builder Don Srull had kits or made kits available and they were able to get one. John said this airplane dropped off his top twenty list and wanted to give it to someone who did not have ten planes on his own list and since I'm pretty new to the sport I got it.

Hello William, your P-13 kit MAY have been laser cut 15-20 years ago by Larry Bagalini as he had a number of kits cut up for club members. I was one of the recipients and built the plane. It has been covered, unpainted and decorating my wall for years too---overtaken by other projects. Through no fault of Larry's a number of the pieces don't quite line up and you should expect a little cutting and fiddling during construction. It was due to the fact that the plans were never CAD developed but good old pencil/pen drawings and when transposed into super-precise laser cut language, errors were developed and several of the cuts are off. Nothing that cannot be easily fixed during the building. Of course, if it is not one of Larry's kits, this is all mindless chatter. In talking to Don Srull (designer) and Frank Rowsome (won FAC scale at Geneseo with it), both emphasized the need to make the wing tip elevons-ailerons very, very precise in whatever the adjustment mechanism you choose. It is very sensitive to the elevon-aileron positions.

OK sports fans, back to the game......

I finally had enough time to work on the fuse saddle areas to develop a solution that works. Here is what I decided to do:  
I used two small 1/16th square sticks to make the rear transition. The front end is the easy one! The sticks reach back far enough to make the transition relatively smooth. It seems to flow well enough with the contours of the underside of the fuse. (I still have to do the other side of the rear transition).  

It should be easy to install the tissue and get a smooth finish. The key will be in the installation of fillets. I will try to make some patterns for those who don't like to deal with them. They are not bad if you have a pattern.

Thanks for your patience.

This is a link to a video of the flight of a restored Bf 109E:

It is very inspiring.

I love the part where it is flying through the clouds.

Made some progress on the fuselage of the 109....
Added the stringers and followed Balsabugs lead on the base for the vertical stab. From what I could make of the wing saddle on the plans the thicker (3/16 sheet) wing saddle fits between formers 3 and 5. I only used 3/32 but sanded it to the formers at each end and the middle.  Still have to make the wing to see how the trailing edge of the wing and the fuselage will fit together.  I did use some 3/32sq to fair in the bottom sides of the fuselage from F-5 to F-7 then sanded this to a rounded and smooth transition to the fuselage at F-7.

I made the gun troughs from rolled paper and white glue tubes, that I microwaved for 30 seconds (a bit too long actually), then mounted the tubes in place and trimmed with a new single edge razor blade.  I still have to fill in around the tubes and the other areas that call for fill on the nose.

I made the formers F-5, F-6,F-7 squared off on the top but I was looking at pictures of real Bf-109 E's today and it looks like there is still a bit of rounded top to the area these formers are stationed.

Here's the pictures of my progress so far on the fuselage.

Just as a bit of minutia, as I was working on the cockpit area and looking for cool color schemes,  I noticed that the E model has a small triangular window at the bottom forward, both left and right, of the canopy. The G does not. If you want to waste even more time on the internet, Google the E and G models and only look for the actual photos of the aircraft---not the plastic models or current reproductions/refurbishments---and you will see. I would bet this will make the mold carving for the canopy a little easier on Mike.

For some good shots of the window (scroll down):   http://www.sas1946.com/main/index.php?topic=2595.0
I tried to copy the shots but I couldn't.

Thanks for the link. I recall this on a model I built years ago, maybe large Guillows.
I'm not convinced of their discussion regarding overlapping panels on the side canopy pane.  Looks to me like shots of thin armor overlays to protect their 6:00. Look at the thickness of the front pane armor.
