No problem. Dollar tree foam is much more fun to work with and makes more durable planesGot it, thanks for the heads up. I figured it would be adequate as long as everything else about the build was solid.

The problem with modelling such a drastic sweep angle on a small model is that the air molecules travel from high pressure areas to low pressures extremely fast as the distances are quite small. With tiny wings this means that the air along the wing leading edge is rapidly turned towards the fuselage and the low pressure area, (required for lift) is swamped UNLESS the speed is quite high, I estimate 50+ MPH!Another turd. I really don't know why. When it broke, I made an even better more aerodynamic fuselage than either of my previous ones, then tried again. This one was actually a little worse than the elmers one. It had basically the same problems-caught a bit of lift but could not gain altitude. I don't know if something is broken or underperforming, if it was weight again which I doubt. I played with the cg a bit but no real result. I think I'm going to take a break from the foamboard for a bit, at least until I get my Trojan and fly it properly. I don't know what it will really teach me about building, but at least it will teach me the flying part and provide a fun distraction. I'm getting pretty good with quads, but I really want to at least get into fixed wing with something.
Even if that depron business is way beyond my skill level, I still appreciate you poking around to find plans and whatnot. I'm taking your suggestion of air flow control augmentation with various devices along the wing seriously. I will likely buy a more specialized motor and stuff for this build and maybe try something simpler with my A pack in the mean time, like a flyer or a wider more basic delta. I also got the little hobby zone Trojan coming in soon to learn on. Hopefully it is good to go out of the box. It seems to be a far better product than the last thing I bought to train fixed wing on.There are a few chuck glider plans you could use and scale up as a aerodynamic test bed. Here is one; https://outerzone.co.uk/plan_details.asp?ID=6189
here is a build thread for a RC model made out of 2mm Depron, (to save weight of course); http://www.rcuniverse.com/forum/electric-rc-jets-198/11624556-handley-page-hp115.html
A test flight?
Hope that helps!
have fun!
Just so that you are aware FB is far stronger than depron especially as a covering and therefore the internal ribs are not all required. You could do the wing covering pieces and then experiment as to how few formers you would require to maintain wing shape. The fuselage could be "Squared" up and possibly made without any formers at all.Even if that depron business is way beyond my skill level, I still appreciate you poking around to find plans and whatnot.

Not a bad idea at all, but I don't really want to create ribs on the wings or do an airfoil at all if I don't have to. Dr. looping Louie's build didn't require one, many ft builds for various planes require no airfoil and it is beyond my current skill level to make an airfoil. Part of why I want a more specialized motor and whatnot for this, I just want this to work with as simple a build as possible.Just so that you are aware FB is far stronger than depron especially as a covering and therefore the internal ribs are not all required.

Just a thought!
