Magnum with Nelson, OK?
Edgar,
I whacked a tree with my 1st Magnum (remember to use high rates when you slow it down) and the wing proved to be very strong. It is everything else I would worry about if your engine turns much more than 22k. Linkage must have zero slop, control surface alignment should be dead on, top line servos, reinforce stab, etc, etc..
