Sorry to hear you wacked your plane that sucks.And your right about a few problem like weight issues i put the os 70 4 stroke on it and still had to add alot of weight.Also there is no room on the inside of this plane i stuck my batterie above the fuel tank.And had to cut wood away for the receiver in the back of fuel tank.But over all i built it in 2-3 days even with work. So it was the most easiest plane iever built.
