Guys, the manual show JR ES519 (45.83 oz-in torque) servos on the ailerons and JR ES539 (66.66 oz-in torque) servos on what looks like the elevator and rudder. I have some Futaba S9650 (63oz-in) that I will use on the flaps and some S9405 servo's (100 oz-in torque) that I will use on the elevators. I use these servos in my 2m Pattern plans so they should be fine.
