1st thing to understand is 99% of the time a plane is going in engine first, I personally tore the carb of an engine (.074) to fix it was about 1/2 as much as the engine itself.. the next most likely thing to happen if you manage to miss the engine is a nice cartwheel.. usually the wing tips and rudder come off here can be fixed...almost any crash can be fixed,its a matter of it being worth the time or not....Rog
