The problem is not in the transmitter is what we're trying to tell you. It's in the physical setup of the control arms to the swashplate from your servos. These regulate through swash mixing on your controller the pitch. But you have to start with the swash in exact center to get exactly the same amount of mix to make the blades go +-10. For example if you have the swash too low you will never get to +10 no matter what you do because of the physical limitation of the servo/swash it can't go any higher. The controller doesn't have anything to do with the physical disability the swash has, to go high enough to get to +10. Likewise for too high to start.


Start with perfect swash/servo placement let me see if I can find the video to explain.

Particularly CCPM 1 and 2 and pitch/throttle curve setup. This will give you the exact fix for your issue.
