Hi tomflier,
I do have seperates with a non-HH gyro, so I do use the revo mixing. But when I use a HH gyro, I turn off the revo mixing. Actually I just switch to a differnet model on the 9CH. (don't you love good radios?)

Do you have the airplane version? Mike (brother #1) has the 9C and the throttle ratchet makes heli flying awkward. We have looked at modifying the ratchet nob to be more like my 9CH, which has very little ratcheting.

I must not have a very good understanding of the CP mechanics (I think I mentioned that before I thought that the standard CP setup on a piccolo used 2 servos for cyclic input, and a seperate servo on the pitch slider for collective. This would have no CCPM, then. Isn't CCPM when you have all 3 servos connected to the swash?
Don't be afraid to point out where my understanding departs from reality. I am asking because I do not know.
