radio systems that lack a suitable channel for controlling the gyro gain.
Gain channel operation
The centre pulse value is set at the factory at 1.51ms. However the Quick-
setup routine will adjust the gyro centre value to accurately match that of
your particular radio system. This accommodates the different pulse length
standards adopted by different radio system manufacturers.

Preparing the helicopter mechanics
Attention to the tail control linkage is important to getting the best from this
gyro. You should aim for an easy-moving but slop-free linkage between the
tail servo and the tail blades. Inspect the bearings/thrust races in the tail hub
for smoothness of operation. Check the pitch slider and ball links for slop
and replace if needed. Some helicopters that have noticeable 'give' in the
tail linkage may benefit from the addition of a rear-mounted tail servo and
rigid pushrod. You should also fit a long servo arm (between 15 & 20mm)
to the tail servo.
Remember that during aerobatic manoeuvres the combination of a high
performance gyro and a fast tail servo can place very high loads on the tail
rotor drive train. While you have the helicopter on the bench to install the
