shrimok 90 problem

[loopking]

ive had a minor crash with my shrimok and now when im inverted it pulls to the left in a hover but it is perfect the right way up if i trim it up when inverted the trim is then out when the right way up have replaced the swash and new ds610 and washout arms apart from this it flys perfect
can anyone shed some light on this as am at the end or my tether
regards

If its not something thats radio related or can be dialed out that way i guess its a case of very close inspection, sounds like something is bent or off centre, maybe triming out on the radio might help track it back t the problem? All the servo's good? i had a similar thing once it was a single tooth on a servo gear that i faile to notice durring the rebuild, what about all link rods? they can sometime sneak in and cause this

I dont have one of these but have seen one close up . I believe the cyclic servos drive the swashplate indirectly via metal torque tubes -could one of these be bent slightly ?

[Edders]

does it climb straight inverted and right way up?

[loopking]

it climes out perfect inverted and right way up when trimmed in also have replaced all the cyclic servos wth new ones

Could there be someting bent or out of alignment causing some phasing? just a thought.

Its a slightly bent flybar from his minor crash.
