Need Help: Gyro setup for a brushless coaxial heli
I have a coaxial heli I'm trying to make work with my DX7 Tx, two brushless motors with two brushless esc and a stand alone gyro.

General wiring:
TX(trottle channel)-esc1-motor1
TX(Rudder channel)-Futaba GY520-esc2-motor2
TX(Gear channel)-Fubata Gyro Gain connector
TX(Elevator channel)-Elevator Servo
TX(Aileron channel)-Aileron servo

I already setup the gear channel as the gyro input in the DX7 (at 50% for both positions)
After setting it up, the main motor seems to run fine but the rudder motor does not seem to respond or turn at all.

How do I setup my DX7 Tx to make it work and is this even possible?
Do I need to mix the rudder and throttle channels?

Thanks, any help is appreciated.

If you give it full left rudder does the second ESC arm?
Some info on the second page of this thread about the mix. http://www.rcgroups.com/forums/showthread.php?t=447808
