I agree. The servos are more important than the PE especially in a 50cc gas plane.

As far as loading out the PE, I doubt you will do this with the 50cc plane. Anything is possible though. You don't have servos fighting each other on a 50cc as you will only be putting 1 servo per surface. Your only chance of high amps is if you have a servo freeze up (which you are in trouble anyway if that happens) or if you have too much throw in the servo and the surface can't go that far. This will bind the servo.

I'm going to assume you have a computer radio at this point. All you need to do is program your travel on the channels so that you get max deflection without binding. Just watch your surface while you program. As the surface moves you are fine. If the surface stops moving and your servo arm continues then you are binding. Come back a few clicks and you'll be fine.

No need for any fancy servo programming devices on this plane.
