RE: 3D Foamy Sukhoi, my experience.
Here's the complete setup:
3DFoamy Raven with G-Force wings
Himax 2015-4100 BL motor
Himax Aluminum 6.6:1 gearbox
Phoenix 25 amp ESC
Etec 3s1p 1200maH Lipos
Hitec HS-55 servos on all controls
Du-Bro micro pushrods on all controls
Hitec Electron 6 receiver
Hitec Eclipse 7 radio
GWS 11.5x6 prop (its a 12x6 with the tips trimmed off)
Ready to fly weight is right around 16.1 or 16.2 ounces with landing gear and wheel pants. Using my fingers, looks like the CG is approximately 3.25 inches back from the LE.
