I'm getting slight tail wag with the following setup:
Goblin 700 gasser
BK BLS-8005HV tail servo
rudder delay 0
rudder gain 38
Overall gain multiplier 1.0

If tired reducing the gain with no success. The mechanical is 90 degrees on the servo horn. Any help would be appreciated

I should also mention this happens in hover at 1900rpm, 2000rpm, and 2100rpm. From what I noticed, I do not get a wag doing pitch pumps.

Hello,

please try to increase Pirouette Consistency to 180 while decreasing Gyro Gain little bit.
Also using a shorter servo arm could help.

Make sure the unit is mounted really hard and can't move in any direction, especially to yaw due to vibrations.

I need to rebuild the engine. After that, I will try those settings.

Thanks
