with the stock JR 3301 servos and properly installed linkages I can assure you that the servos are up to the task. Myself, Tom Dodgen, Larry Kramer and a few others that I am sure anyone who has been to a Jet meet in the US have seen first hand do not baby our airplanes in fact push them to the edge of their envelope with no problems whatsoever.
Just a correction here, Larry has been using high torque Multiplex servos in his Bobcat since day one.....
