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 challenging: convert all control surfaces to variable airfoils. Neutral for straight flight.

The Wright Brothers used a variable warp wing system to control their aircraft. I believe it was Glenn Curtiss who thought it impractical and invented ailerons.

Actually I believe Curtiss used ailerons simply because the Wright brothers patented the wing warp system. At the time, wing warping was probably seen as the most elegant solution.
