enter image description here THIS IS JUST A SIMULATION OF THE INTENDED AILERON THAT I'LL BUILD AND PUT ON MY HOMEMEADE PLANE.(I scrampled all the materials I could find in my backyard). Do you find any abnormality in this aileron in relation to the aileron on real planes('cos I have never really seen the aileron setup of a real plane)

  • $\begingroup$ Looks like you have the basics of the wing mounted control horn down. Maybe change the aileron connections (both ends of the threaded rod) to a ball & socket setup so there is no 'slop' in the control from a rod in a hole; don't want any fluttering from loose connections. $\endgroup$ – CrossRoads Apr 5 '18 at 16:32

    $\begingroup$ Your control link to the aileron will fail in compression from buckling long before the expected flight loads are reached. Try to use tubes, not rods. $\endgroup$ – Peter Kämpf Apr 5 '18 at 18:08

For a non-working prototype it doesn't look too bad - you have a bell crank connected to a control arm that's attached to the aileron.

However, the devil is in the details and messing up a detail can kill you.

  • You will want to use acceptable materials and construction techniques (See AC 43.13).
  • You need to ensure the bell crank is the right size so the control forces are correct (neither too big or too small).
  • You need to ensure the aileron is the right size and shape and travels the correct amount.
  • You need to ensure your hinges are of sufficient quality (hardware store stuff will break and can kill you) and are attached to the wing safely (losing an aileron can kill you)
  • You need to ensure your aileron isn't subject to flutter (which can kill you)

If you haven't already, contact the EAA and get as heavily involved as possible. They have an incredible amount of information available about how to safely design and build an airplane from the runway up.

Not sure what specific feedback you are looking for here, but if the question is "will this work?" or "is this a good idea?" Then the answer is probably not. If you never built a plane before and have never even seen the design before, just making it up as you go is not a good idea. If this is a toy remote control plane, then you could get away with it. But if you intend for a person to fly in this, then you do not want to do this. For your first plane buy a kit, or at least get plans/blueprints for a proven design. Once you know how these things work, then maybe start improvising a little by modifying existing designs. Sorry to rain on your parade but I think you are taking risks that you do not need to take.
