I have built four of these and they fly great on two channel.I print them
them out using 3x3 preference on Microsoft printer . IT comes out bigger than original and some changes like slot for fuselage and motor
have to be adjusted and the slot at rear of fuselage. they all have to be made smaller but then to me it flies even better than the original which I have made and also flies great. The bigger one is a little slower and works better for my grand kids
