Position Hold

[GHIDI]

When I activate "Position Hold" the tail of my Goblin 570 has small vertical oscillations. What could be the problem? The gyro is set to 70%.

Hello,

you can try to decrease Horizontal Correction parameter in the GeoLink window. This should help.
If the problem is appearing also in a different modes, then the problem is rather different.

It could be low head speed, too tight blade holders, too high Elevator Filter or bent main shaft or some assymetry in the rotor head.
