Flybarless Rotor Head Systems > V-Bar tail problem

I have the V-Bar and the tail will always go to one side. I reversed it and the tail will do the same just the opposite direction. Every thing is set up perfectly minus the tail.

I am having a bear setting up my tail on my Logo400. It worked perfectly the first two flights and now drifts/kicks out all over no matter what I do. This is my fourth Vbar heli setup and I have never had a problem like this.

I am using the 9257 tail servo and a DX7. The trims/subtrims are zeroed, and my control arms are at 90 when neutral. I used the factory presets as a starting point and my gain is already at 100 with continued poor tail control.

Any suggestions?

Thanks!

Ted

On which side of the frames is your tail servo fixed?

Remember that the preset has been made (see at the preset description) for full size tail servo.

If you use a midi servo, maybe you fixed it on the other side frame. So the tail pre torque compensation will go the wrong way now.
To fix, change direction of tail sensor, stick and servo (expert soft).

I was contemplating switching out to a 9254. I will look at the servo directions, etc. It is mounted on the same side as the bigger cutout (left frame).

Hopefully that will work.

Thanks guys.

Fixed it. Thanks to inkspot, I saw that my servo was not centered on the Vbar settings. Now I'm rock solid at 60% gain. Duh...
