unstable helicopter rotors animation (rotation in transform node)

[Coz_y_not]

The body in grey is moving. The main rotor in orange and tail rotor in red are rotating based on $CEX $CEY $CEZ, and are supposed to follow the motion of the body, but it's jittery and keeps moving from it's place.

Am i doing it wrong? is it doable with transform or do I have to use APEX for this kind of animations?

main Rotor animation transform

tail transform node

you need to check pivot point position. looks like it not in the rotation center

Although I have changed the pivot

it still has that jitter

You need to place it manualy, you object not symmetric

it's a long animation, I can't place it manually for every frame, and the body is moving. it is symmetric 3.3313 x 3.33132
