Thanks for the reply. I will build my first plane with fan fold. I am looking at the Ultimate Bipe 30" or 3dx.

As far as the spur and pinion, I am confused. I am looking at Horizons site. They have Spur gear, 60T, 62T,64T, etc. Is that the gear on the motor? Which one is a D gear?

They list a NYA PINION GEAR D: EPS 300C/350C. I assume that is what I need.

The motor is: 350C BB MOTOR & GEARBOX, 6.60:1
(GWSEPS350CDS)

The pixie 20p has BEC so I wont need a separate battery for the receiver.
