Put a 2206 2600kv with a 6x4 prop 30 amp esc 850 mah 3s and it rips through the sky. I jave a teacher in my school who says they have experience with planes and is interested on foamie combat so I bought a new motor and esc and built another mini f22. I put a 2.5 by 13 inch piece of foamboard with a barbeque skewer in it along each wing and I am glad I did this f22 really moves with this motor. 2 minute flight time and not efficent at all in regards to battery. The black gorrila tape is where the reinforcment is.
