500x tilts right sereverly on take off

[jmurray74]

Was flying fine and on the next flight it decided to tilt abruptly to the right on take off.
I did notice on the last flight a slight tilt to right( before that it would take off perfectly straight) but it flew fine.
Flying in sport mode on bx.
Any ideas.
Thanks Jim

Uncommanded roll to the right is the classic BeastX response to vibration. A good first step is to remove the main blades and spool the heli up, while watching the swash to see if it deviates to the right.

its called the RROD . right roll of death..its due to vibrations to the fbl unit..try different mounting tape under the fbl like 3m. then look for bad bearings or out of balance blades..its pretty common on the 500x. ground the boom to the motor mount too. the search feature here is pretty good too..

I have tried everything and still roll right. Could it be the bx.
This was a good flyer,but now is a piece of s???.

Tail was problem . Bent blade hub and out of balance blades.
Flies good now.

how did the hub get bent..glad you got it sorted out..

I guess in crash

you said it was flying fine. you didn't say you crashed and then It was flying tilted..

Nice to hear your up and running again: make sure you don't have any noise or fuzz (buzz) in your tail.
Also if you crashed you should change your feathering shift and probably your main shaft.
Good luck..

Sure you're running the servos at the right pulse/frequency so it could be a problem with the beastx unit. One that came on my 300cfx killed servos left and right with no rhyme or reason. Just a thought
