Hi, first-time setting up the unit. Need help with the tail movement please ?

The servo acts correctly against the transmitter input - moves in the opposite direction. However, when the heli is powered and I rotate the heli horizontally, the servo follows the movement, instead of counteracting it.

I cannot find a parameter to reverse the tail / rudder ? something, or somewhere else that needs to be set and corrected ?

Hi,

this parameter is in setup Wizard in our software and also in the Sensor tab, Z - Yaw.

Thanks ! !!!!

Fixed Maiden for the unit in the morning ,

You are welcome.
Make sure that Piro Optimization parameter is configured after configuring Sensor compensation direction.

Hi, the heli and my nerves survived the maiden session !!!

You were right : the piro needed to be reversed. whether it was wrong before doesn't matter, your comment made me look and all is well in this regard.

I'm using throttle curves at the moment and no stabi. I spend time to find the gyro settings. Very windy for the little 450x.

I have one problem that I need some help and directions on please ?

Tail holds and stops well. It is quiet in fast-forward flight, but at high headspeed (85%), it wags violently when I pull up at the end - really violently. To get rid of this, I need to drop the gain way down so the tail wags slowly and doesn't hold well.

how to address this, so I can use the right gain level please ?

Great,

most probably you will need to configure Piro Consistency parameter. If it is too low, rudder will not hold even with too high gain.
What is your current value?

Thank you for the super-quick response and the efforts !!!!

It is set at 160. (default ?)

You can try for example 165 - 170.
