FYI,
For safety and reduce the risk of lost of plane, you may want to modify the elevator for two servos.
As with the comparf corsair, it appears to be an easy 'mod'.

Initially, I used HS-645's but changed to two HS-7955's giving the plane a total of 666 oz of torque for the elevators (7955's also used on the ailerons).
