You did flirt with disaster and came away with your plane intact. Those servos might work for flying around in big circles, but put any pressure on them to perform in a 1.20 size plane and they just don't cut it. I use lots of the Futaba 3305's or Hitec 645's in my bigger planes. They are more expensive, but you'll save an expensive plane... it's the price we pay for going larger. I'm putting together an Air Wild 38% Giles... Over $900 for the servos on the control surfaces. Plus a cheap $54 servo on the throttle.... this becomes more like an obsession I'm afraid.
