One thing I learned with the heli's is to use the throttle kill switch when making any adjustments, so that if i bump the throttle the motor wont engage. I think this can also be used on the plane setting, at least on the DX6i, my mSR is setup under plane, and it works.  (i'm also training myself to use that instead of just chopping power when the heli is about to hit something, if I chop throttle on a CP, it will go down, hard.)
