Default Can you adjust gyro gain on a Heli-max CPV3?

Anyone done this or know how? My tail constantly turns side to side, forcing me to chase the tail constantly, even in a hover!

I think I figured it out. I wanted to post this, in case others might need to know.

Pictured below, you can see the circuit board that sits on the left hand side. There are three tiny adjustment pots, arranged vertically, on the very front of the board.

On the CPv3, the bottom one is marked "SEN", so I started there, to adjust the trim centering. The red arrow is pointing to the bottom pot in the pic.

The middle pot is the gyro gain. + or - .

The top pot is the left/right bias, meaning if your heli spins one way noticeably faster than the other, you may need to adjust this.


Remember, make adjustments at your own risk. A little seems to go a long way, and be sure to mark original positions if you try to adjust them. Do this at your own risk!

***EDIT*** since posting this, I actually read the freakin' manual, and made some inportant corrections to this post!
