Ok I had a good crash. I went in the dirt tail first. I had to replaced the boom, tailhousing (upgraded with copter x metal tail), main shaft and feather shaft, blades (325 pros), and new belt. Now the problem I am having is when at hover the whole heli will oscillate up and down from tail to nose. about a inch or so. It will go away in idle up. I have messed with the gain on the gyro (gy240) and the head seems to be balanced. on the ground it seems fine also. So has anyone ran into this befor. The only other things I can think of is the main head block or the main gear. Oh its a metal head on this bird also.

trex 450 sa
