HeliQuad rudder 4th servo not mixing with the collective - acting as tail rudder

Disregard this question/comment, I figured it out following the advice in this article:

Rotor speed control and (H_RSC_MODE set to XX ) behavior

Hi Bobby: So in both cases of RSC Mode 1 and 2, the systems is looking for a signal on Input Channel 8. In Mode 1, after arming, Arducopter will pass-through the Ch8 signal to the RSC. I’m currently using this on all my ESC’s with YEP ESC’s (YGE clones). I allows me to have Ch8 on a knob so that I can vary the RPM in-flight. I also have a switch setup on my radio which operates like a Throttle Hold switch. When it is “down”, it cuts the Ch8 signal to minimum. When it is “up”, it sends a C…

I just set my RSC to channel 8 (heli setup), then on my radio, I tied channel 8 to a knob so now I have FULL control of my RPM with fine tuning increments (using the knob)! Works beautifully (in fact it works BETTER than before with my governor because now I can very slowly spin them up and “lock” the RPM to whatever I want it to be without using my PC to edit the governors settings)!. This is AWESOME!
