Tiger:
- the little Axi is the best way to go...... We use this motor, Poenix10 ESC, and 2S 730 - 860 packs. GWS Rx and the little Cirrus servos give me a weight range of 6.2 - 6.7 ounce AUW, just depends on which pack is on it.
-the CF bracing, or equivilent "fishing line" is a must.... has nothing to do with the wing, but in keeping the tail stiff to the wing
-I simply cut a 2" circle out of super light ply for the motor mount
The F3A shocky will not be doing much 3D...... too small control surfaces.... I think all others will 3D..... I have the Extra-300 and the Yak..... both are great. The key to having fun with these is to have them UNDER 7 ounces and move the CG back..... we fly in very small areas with this setup.
Good Luck
