•FEATURES
1
The FP-8SSHP is a digital proportional R/C set with PCM (Pulse Code Modulation) for helicopters.
The system is extremely noise and dead-point resistant digital proportional R/C sets with a microprocessor in the transmitter and receiver.
The FP-8SSHP was specially developed fo r FA I RC aerobatics F3C use.
Please read this manual before using y ou r set.

•Revolution mixing compensation. The revolution mixing (pitch control -> rudder mixing)
