My polyhedral wing tips so far have been 2/3rd's flat and 1/3rd in the two tips. And that has worked OK. So 6-24-6 should work well for you. And make the rise about 1-1/2" on each tip. That seems to work well.

Do you plane to put ailerons on the wing? It will fly well without them and that can even be added later if you want. Flying it RET at first is good for the initial learning.

R.e.t stands for rudder.elevator.throttle.
And it needs less dihedrel in the tips.
Put the middle part of the wing on a flat surface and at the end of each wing tip add a object that is somewhere between 1 and 2 inches high. But remember whatever you do do the same for each side otherwize your plane will want to turn with out you giving it any control input. Just my 2 cents.

I haven't done that. I saw a recent post where this was mentioned:


I think that one comes with some software included. I know there are some freeware flight simulators but don't have any experience with any of them. Have you tried a search on the forums for flight sim?

Be sure to read the stickies, there are lot of easy to build (and easy to fly) models in them.
Construction tips are abundant.

Ze plane! Ze plane!

I don't know if you remember Fantasy Island (a U.S. TV program) but I seen an airplane there and it looks like it will fly.

You are using different materials and building techniques so we'll all learn from it. Proceed gently and you'll do fine.

The wing will be fine, the dihedral will give you the stability, and it will all work out.

I don't fly where I have runways or smooth areas to land. So my landings are almost always intended to slow the plane and lift the nose so that it stalls and flops into deeper softer weeds and grass. So I use prop savers, stop the motor before landing, and don't have landing gear of any type.

Ihave put some tape on the bottom of planes with a fuselage to try to miminize damage from rough field landings. But that doesn't work well on a stick. On one of my sticks I pul a piece of plastic on as a tray and skid that protects the servos and electronics in landings.


Landing gear will have leverage because of it's length and that can make it damage the points where it attaches.
