hey guys, i don`t know if i`m in the right forum but hopefully i can get some help. I put together a showtime50, and put a saito 91 in it, made sure the cg was right, it was just a hair nose heavy
a took it to the field this weekend for the first time, ok... here`s the problem..... when its at mid-throttle it flies strait and level, if i go to full throttle it goes nose up, i mean it could hover, someone at the field said the thrustline is off and to shime the motor down slightly, and this is normal for showtimes....... does this sound right???? any ideas???? thanks for your help.

My showtime was difficult to trim out too. I still don't have it at 100%. Mine pulls nose to the left when I go from level flight into a quick vertical. Im assuming it needs a washer or two for more right thrust. Does this sound right?
