Galaxy Scorpion Twin. Although this model is still under construction, the PCM 9 channel Futaba radio set-up has been fully tested. The reason is the original uses 1 throttle servo but I am using 2 miniature Futaba S3101's and a Heli set-up on my Field Force 8 (8UAP). This allows the use of throttle and pitch curves to fine tune the engines rpm's all the way up, unlike a linkage system. The other thing it allows is the practicing of asymmetrical flying, e.g. engine failure by setting idle-up 1 to have a throttle curve (left hand engine) flat at tick-over and normal curve on pitch (right hand Engine). Idle-up 2 is set to be the opposite. Rudder offset is possible for each mode too linked to throttle/pitch response |
