I do have the linkages setup for 3D throws but have tried to maintain as much mechanical advantage as possible. I only run into problems when I transition from an elevator into a harrier. I have the ailerons reflexed slightly while I'm doing this to reduce wing rock. So, I've got four digital servos working fairly hard for awhile. I figured it was my bad for abusing the BEC. I'm assuming I should install a separate BEC if I plan on keeping this up? Lift the power pin from the receiver lead and I'm good to go? Thanks much for the reply, by the way.
