yes, i had a 130x which did this, i reckon there are loads of 130x out there with this problem, and it is a problem. My tail drifted and the swash tilted, after sub trimming it out the heli flew 100% better.

just done mine, WOW what a diff in take off and hover only put 8 ail and 3 rud but now after roll left (as standard) once corrected it just sits there, hovered in one spot for close to a minute in the living room whereas before i would of had to drop it because of over corrections .... dont know about flying outside yet but deff improvement so far......

My orig 130x did this. I sent it back to HH and got it replaced. The new one worked perfectly without subtrim ..
