Unfortunately, the combination of heat wave and my crew's wish to transfer the game to full 3D drained all my time and energy for this project. However, this is just the temporary drawback, this project is not dead in the water (nor it will be, the thing will fly, that is for sure, one way or another).

This is more refined drawing of the airplane. I will let it "sit" for a day or two and if I am still satisfied with it, I will start calculations of the basic parameters. The anhedral or dihedral, which looks more appropriate since it is a high wing, angle will be added in the final drawing, before drafting.Attached FilesLast edited by Versus; 26 Aug 13,, 17:17.

Also drop the one piece fuselage Idea. Build it with balsa sticks using CA glue then cover it with tissue or heat shrink covering. It will be much lighter.
BTW: Your GC always need to be on or very close to wing main spar.

I had the similar idea for the hand held foam cutter, mine looks more like potato skin "piler" for the smaller curves. For the bigger ones, I am planning to make something like router but with manual control. Good thing is that the heat is finally over and my workload is lighter these days so I am working on this project with the increased paste. Thanks for the advices, I will post the pictures of the machines once they are completed (within a week or so).

I think that this one is the one that will go. No fancy curves, no fancy complex polyhedral's just plain and simple. Now, lets go to the abysmal world of partial and differential equations...Shrug!Attached Files

And some real life photos, but they are not that interesting. I've made a test yesterday with the hot glue, since I wasn't sure will it stick to the kind of insulation foam we have here. But it did and the bond is very strong (but not on a load bearing scale). Than I did a couple of "static and dynamic tests" (mainly meaning trying to separate two pieces of the foam by hand, twisting the pencil between two palms, with the foam attached to it (centrifugal or g force test)...). After these caveman tests, I came to conclusion that this foam and this hot glue will do the trick for the future and also our cat approved the tests as it watched every move of the foam during the testing. So now the materials are solved and, to large extent,the manufacturing process. Since this model will evolve into fully controllable RC later in the game, a couple of issues arise. First of all, as I said before, the construction will be modular. However, the batteries and the electronics are fairly standard and since they are necessary for the RC as well as the engine mount, these two sections will be defined first. So in the next post I will deal with the fuselage (actually making it). Also I've manage to find relatively simplified formulas for this so hopefully this project will move at a faster pace from now on.
Slowly but surely, its coming to life.:Dancing-Banana:Last edited by Versus; 08 Sep 13,, 13:33.
