RE: Engine size on Kadet LT 40
I flew one with a Magnum 75 on it, had the wings clipped one wing rib bay and no dihedril, it was a blast.
The owner let another guy fly it and he buried it past the muffler.....distroyed the carb so we put an MVVS carb on the engine and made it real strong.
If you have the experiance the plane will do it, well.
