Markind. Get rid of those mixes!!! You have a problem with your head and servos and you are masking it with those Pmixes. The problem you have is called UNWANTED SWASHPLATE INTERACTIONS, it's very easy to fix once you know how to identify, diagnose and cure it.

What causes U.S.I.? Uneven E.P.A. settings. How can we tell if our End Point Adjustments are off? Easy. Let us disconnect the motor from the speed control. Now lets flick on the idle-up switch. Slowly move your throttle stick all the way up and down a few times and observe the swash from the front of the heli paying close attention to the ball links on the front. When you get to maximum throttle position do the two ball links stop moving at the same time? If they do does the ball link in the rear stop at the same time as the ones in the front? I bet they don't. That is because the servos reach their maximum travel before the one of others and this will also cause a difference in speed among your swash servos and this will cause the swash to move unevenly which translates into an unwanted change in direction.

How do you fix this? Use your E.P.A. settings to match the stopping points on all your swash servos. I don't know if you understand what I'm saying here but if you watch these [link=http://helifreak.com/viewtopic.php?t=12455]CCPM setup videos[/link] by Finless Bob then these will explain everything. He is using a TRex in these videos but you can apply this to the AxeCP and any other heli that uses a CCPM swashplate.
