I went out today and had an instructor maiden my trojan, it didn't go well...It has a O.S. 91 4 stroke with a 65 inch wing...The instructor did the taxi test and all looked good, then he went for take off...This thing shot straight and it was hard as hell to control, it hovered over the pit area and everyone was runnin for cover...He finally got it back to the field where it crashed into a fence (minor damage)...You might say its tail heavy but its balanced at 4 1/4 from the leading edge like the manual says...I even made it a bit nose heavy...The instuctor did increase the travel on the elevator throw by a hell of alot before the flight ( He said he likes alot of elevator, I don't)...I think he might have over controlled it , what do you guys think?
