    Sharp bends over spar vs. wing ribs

    Has the question ever been asked about the reason for most if not all of the wing builds using foam board utilize the method of creasing and sharp angle bending the foam over the spar as opposed to the use of wing ribs? Other than the obvious answer of simplicity and ease of build, I am at a...

    Does anyone have aerodynamic curves for the Tiny Trainer aileron wing airfoil?

    I am using my Tiny Trainer for a project and it would help if I have the lift vs AoA curve for the aileron wing. The most pressing need is for the stall AoA. Any help will be greatly appreciated!

    Variable airfoil wing.

    Challenge: 1. Try to make an aircraft with wings that you can change the airfoil of in flight. 2. See if you can remove the ailerons and instead change one wings airfoil at a time for roll. 3. See if you can essentially flip over the airfoil in flight and get lift while flying inverted. Extra...

    What would be a good airfoil for a FPV flying wing

    Hi everyone. I am designing a flying wing. It is going to be 1m wingspan and I'm thinking that eventually I will add a small FPV system and use to teach myself FPV. I have designed it to be similar to the raptor 100 which I saw in this video http://www.youtube.com/watch?v=5W7Zz4YVEqM I'm...

    Foamboard Shrike

    Hello. I'm building a Shrike from out of an free-bee issue of Flying Models Magazine but out of foam. So far the scaling up from an Ultra-Micro setup has been great. However, I have one Question: <<<:confused:This is a speed plane, Should I build it with a full airfoil, or would a flat foil...

    Video of stalled wing + unintentional crash

    Thought I'll make a video of the air flow over the top of the wing at stalled conditions. Was doing fine until it went into a death spiral on me .... http://www.youtube.com/watch?v=r4YAMyiiM_I
