First, Here's my setup:
New Align T-rex built from kit;
Walkera 3200Kv brushless with 12t pinion;
E-flite 20A ESC;
2S3P 2600mah lipo;
TowerPro 9g servos on Ail, Elev, Pitch;
Esky 6g servo on Rudder;
Align HH Gyro.

The gyro is mounted vertically on the left side of the tail boom mount. The tail pitch motion is smooth (with the servo plugged into the Rx aileron, the motion is smooth, crisp and at the full speed of the servo). Gyro wiring is down the left frame to the rear mounted receiver. Front servo wiring is along the bottom of the right frame. A Deans whip antenna is mounted beneath the right front skid brace, pointed rearward

I am using the on board gain adjustment on the gyro. The lower 1/4 of the pot gives rate, the upper 3/4 gives heading hold.

The problem:
With no motor (throttle hold), and the gyro in HH mode - the tail servo moves to one extreme as it should. But, in rate mode, the servo motion is very slow and delayed has it attempts to follow the rudder stick.

With the motor, the gyro in HH mode, and the heli getting light on the skids - the heli yaws in one direction and is very delayed in responding to opposite stick. When it does respond, it goes full tilt in the opposite direction, even though the rudder stick is released at the direction change. In rate mode, the rudder seems to respond correctly, but very sluggishly.


Any thoughts? ? ?

Thanks!
