All I can find at the moment is that it is Futaba based. I am not sure about the Futaba rx layout. Normally it would be
Channel 1 Aileron (front right servo)
Channel 2 elevator (center rear servo)
Channel 3 Throttle (esc)
Channel 4 Tail Gyro
Channel 5 Gyro signal wire (single wire in a servo connector)
Channel 6 Pitch (front left servo)
Hopefully someone can verify this.
