I dont fly jets but still fly some 150-190mph planes and use only Hitec servos. My favorits are HS65, HS 85/87, HS5245, 7975HB, 7940, 7945 and 7950's. For flaps on large plane I use a spektrum 600 although its a retract servo it has a speed of 1 second and 260 ounces of torque metal gears and fully programable.
