I watched a guy at the field try to launch a small spitfire on a catapult, 3 times unsuccessful. Smaller than combat size. He had a .25 in it. The plane seemed to torque over to the left every time he launched. He said he was running at about max, or close to it, throttle. Didnt get to try it throttled back. Third time had too much damage. I would be careful overpowering it. Just my observation.
