Thanks for the wiring diagram posting. I am just curious, how does the ESC/Mixer get the rudder control signal from the receiver (CH4); just that single orange wire?
With the HH gyro upgrade Heli-max tells you to plug the gyro control into CH4 and move the orange wire down own slot, CH5. What's coming on CH5? why not just leave out the orange wire since the ESC/Mixer is not controlling the tire motor anymore.
Any ideas?
