My new experiment, It's kind of a Bi-Wing MAV with 3 rudders and 2 elevators. 2mm Depron, 6'' WS and the airframe weighs 4.90 grams. I thermal molded the wings airfoil and dihedral. Planning on using a 6400 with the micro J3 Cubs motor/gearbox and a Hyperion 70mah bat.

I drew the airfoil on the ends of 2 boards, rough cut them on a table saw by ripping them at different blade angles close to the airfoil shape. Glued them together and sanded my cuts smooth.
I then made my 4 miter cuts at 9 degrees to give myself a 18 degree Dihedral. Used a sliding power miter saw for this, then glued the 3 pieces together.
Lightly tack the Depron wing to the wood jig, and wrap a thick piece of chair cushion foam with Ace bandages and bake in the oven, 225* for around 40min.
