I have built 2 of these planes, the landing gear is week you need to beef it up with b&b specialties landing gear stiffeners, and the mounting box to the engine. where it attatchs to the firewall will break I used 2 pieces of 1/4" thin ply with blind nuts and epoxied and sandwiched together through the side of the fuselage, plenty strong up here now, my honest opinion the gp superskybolt is a better plane mine has a saito fg21 4 stroke in it
