I would agree to a point. I have a BAF Juka with the recommended Scorpian motor. It has insane power, as do most of my foamies but it is easy to control with the left stick. If you have trouble with the left stick, then you probably have the same issue with the rudder. If you can't control both, your in trouble.
Now that being said, the power needs to be linear, so be sure and set you end points correctly on the ESC.
I would rather have the extra power by pushing up the left stick then go to the stops and not have enough. It just takes burning milliamps to learn and get the technique down.

It IS possible to have too much power in these airplanes.
