Hey guys, just fix my Trex 500 from a crach day before yesterday, where I had to replace Tail boom, main blades, fly bar, main shaft and gears on two of my futaba servos. I started to hoover, check the trackin which seems to be fine, it seemed very well over all except tail is rocking up and down. It used to do this before when I was decelerating from high speed foward flight but it was a lite rocking motion but now it is very severe and cant figure out whats the matter. By the way my 450 is grounded because of the same problem.
Thanks for any help you can give me.
