Aerobatic plane for Spee d 400 electric
by Phi lip Rawson
C
Philip Rawson 2003
The prototype used a Graupne r 6v Speed 400 motor with 3:1 offset gearbox
and 8 cell Sanyo 500AR pack. The best prop for this combina tion is a 10"x4",
but these are not easy to find; a 9"x6" is a good substitute.
Hitec HS81 servos were used for elevator and aileron control. "9 gram" servos
will do the job, giving sp ace to fit a rudder servo.
