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.

My first time using EPP, not sure if I like it but I haven't crashed it yet.

I overlaid the first 2 pics on top each other and came up with this plane.

17" wing span, just under 37 grams, all S-bach equip,(-2servos)KFM4 with 3 layers of 3mm Depron,Hyperion 180 & 240 batts, 4530 & 4040 props.With the 4530 prop it cruises around nice and smooth but still pretty quick. With the 4040 prop "OMG" my new favorite plane to fly, having more fun with this than the Stryker.

9'' span from 2mm Depron (looks closer to 1.5mm to me) with a Vapor brick and gearbox (with ball bearings,J3Cub motor)and a carbon fiber 5030 prop (shoutchen gave me a great deal on these, can't thank him enough) 12.12grams and RTF with Hyperion 70mha 14.48grams. Heat molded the dihedral in with a wood jig and the oven, worked great. Just did a thrust test and this little setup pulled Just over 28 grams (WOW)
