This explains why I like this hobby so much. "Normal" has never been a word used in connection with me. Grin

Jeeze, Normal, like the way you normally put silkspan on model airplanes...

Wet or dry, cut or torn edges, then there is the adhesive, nothings normal or even standard. Shocked

BTW nice work

All the best,

Well with this design there is nothing normal or traditional. First off it's a 70's style pattern ship, in miniature. Second it's a keel,  former and stringer construction that is not normally used in a small sport design. Often in these designs use sheet wood sides and perhaps some former and stringer construction on top and bottom. Third, it's not even close to anything 3D style, with small ailerons and small elevator. For this motor, most often found on flatout type foamys, this is pretty far away from that foamy flying thing as one can get. This airplane will have to use it's wing for mostly everything and vectored power will be used to just pull the thing along. I will most likely not be able to fly this thing in the normal indoor RC airplane flying venue. I will have to fly it in the park as a park flyer. I hope it will fly fast and smooth, but we will see. Certainly will not be doing any 3D stunts, but that is not the intent of the design. My thoughts on my building madness.

Thank you to the other posters for interesting ideas and moral support and cheering. It's been a long time since I did some serious building and this was as good a project as any.

Time allowed for the construction of a Stabilizer and Elevator. Built from 1/8th inch by 1/4 in strip in a simple manner. The elevators are from 1/8th inch sheet tapered to 1/32 in, at the trailing edge. I am pleased how rigid this stab is, and it will serve it's task well. One thing I was wondering was that I may have made this stab too small, but then it's meant to be a fast airplane and this stab has a fair amount of area. I don't think that I will have any problems with it. I have yet to cover it and the elevators are not glued on just yet. I will do a covering task soon.

Since the last images, I have completed the stab covering and final control links. I have also completed some trim covering for the canopy using black tissue with a blue trim stripe around the canopy. Next stage is design the wing structure and build the wing. I have yet to decide on wing mounting but will cross that bridge soon.

Started on the wings, and there is nothing traditional about these. They are built in a half shell, with the top flat on the board and then the bottom will be added later. Ribs are starting out as stacked and formed but will soon be sliced up. The wing has two main spars and the ribs are sliced and laid in notches in the main spar. Almost all the wing is made from 1/16th sheet.

Might I ask what is the benefit of the split rib method? If it is to build a true wing isn't much of the accuracy in how you split the ribs (and spar (shear web))?

No direct benefit Konrad, just that this is the way it's going in the "make it up as I go along" project. I wanted to just make a wing and so far there is little madness to my methods. I beam, split rib, was a popular method on the east coast in the mid fifties for control line. I am just making a wing like I made the fuselage, split. I will let you know how it goes. Nothing is pre-planned. Just having fun being creative. There is nothing about this build that is thought out before hand. The original sketch was for a .60 cid project that never made it barely out of the cad program. A flat surface is it for anything true... Either I will like what I get or hate it.

Cheers

Bruce

It's all good. I just wonder about the ways folks skin a cat. I ask as I hope to learn a better way.

Al the best,

Ya, no problem Konrad. What is interesting to me is that I can at the last minute, decide on how to employ the construction method based on available materials and a sense of what seems to work out. I suppose all those years of looking at plans, and building so many other models that I am now not constrained by my past inexperience. That being said this make as you go approach is not for the beginner. I suspect that you would not have any trouble working this way either. The Depron people seem to have a go of it with using foam, not my cup of tea though. So thanks for going along on this build and we will see what I arrive at in the end.

The so called Detroit wing construction Bruce? Your free running construction approach is interesting to follow.

Well that was the method that I was referring to but this is a far cry from that as the spar in this project is not one piece as it is in a Detroiter. Thanks for following along OZ.

I built a couple of models a number of years ago using a slight variation of the "split wing" technique.  The main difference was in the ribs, being more the "sliced" variety.  Almost like building two wings (one piece spanwise) - somewhat tedious needing four identical spar segments that were later joined to form a one-piece unit, but once everything was together the wing was nearly impossible to twist (and that was BEFORE covering!).  Another identical wing was made using "standard" construction and selected wood was 15% heavier and not nearly as torsional resistant - even after covering/finishing.

A fairly recent V-tailed sport design (SWALLOW) that appeared in RCM&E (around 2003) uses the construction method.

It is tedious Pit, but this wing is interesting as it is rigid. So far I am pleased at this outcome. The ribs are sliced from normal, traditional ribs. The second picture is the same wing with one bottom main spars added. I will flip the plan over and build the left wing half soon.

Ok good, it's not apparent at first.
Here is another image of a complete right half wing.

Left wing built same as the right wing but quicker. Many of the ribs were prepared during the building of the right wing. the second image of the left wing flipped over and the bottom half of the main wings spars installed. This wing is now ready for some ribs for the bottom half and then the whole thing gets sanded to final shape.

Resurrection

I have taken this particular build off the shelf and have given some thought as how to complete it, and as usual with this build will make it up as I go along. The wing has been joined and has yet to have ailerons constructed. Here is the wing in a test fit on the fuselage. Since then the wing has had the center section mostly sheeted
