hmm... but if i fly smothly, the extra power and weight wont be a problem? ony full throttle straight forward. the wing cant get too stressed of just that?? also, i can adjust the end points so the airframe wont be overstressed.

ive tried to tow with the OS40 2stroker, but its a bit dangerus since the engine barley can tow the trainer + the sailplane.

sry for the english.
