Tail problems..

[sacko]

On the Beam, spec as follows;

Scoprion 60 amp commander
Scorpion motor
AR7000
401 + 9257

When I spool up and the skids just leave the floor, for 5-10 seconds the tail kicks around ( 4" in either direction, then maybe 2", I cant really see a pattern).

After that, it settles down and hovers fine but with constant rudder input to the right. Its setup using Gear and the Travel adjust. After 1-2mins of flying the 9257 is pretty warm too.

Anyone got any ideas?

Have you flown it after changing the screwed main shaft bearing? If so and it's still doing it then I'd take apart the tail grips an check all the bearings and re-grease the thrust races and also check the 9257 internally after your slight crash with the 450 the other day

Yup still the same after the new mainshaft bearing.

Its wierd that it only kicks around for 10 seconds then goes stable.
