It will also be necessary to set the correct idle speed of the
engine when the Th rottle Hold Function is activated.
This idle value is located within the Th rottle Hold Function. This
will allow the engine to remain at idle when practicing autoro t a t i o n s .
6. Revolution Mixing
It will be necessary to adjust the revolution mixing to pro p e r l y
compensate for the torque of the engine during all flight
conditions (except autorotation). Since there are many variables
that can alter the value of the revolution mixing (engine, blade
pitch, fuel, etc.), it will be necessary to fine tune this function
during test flights. The following values are shown only as a
s t a rting point toward achieving proper compensation:
7. Gyro Gain Adjustment
It will be necessary to adjust the “gain” or compensation of the
g y ro to create the correct amount of “holding power” necessary
for a solid neutral tail ro t o r. The intent of the gyro is to
compensate for abrupt movements, or wind direction changes,
working in conjunction with the Revolution Mixing Fu n c t i o n .
For hovering, it is recommended that you start with the gyro gain
at approximately 80°, and continue to increase slightly until the tail of
the helicopter “hunts,” then reduce the value slightly.
This same adjustment will also be necessary to achieve pro p e r
f o rw a rd flight. Generally, the gyro gain for forw a rd flight will be
a p p roximately 10%–20% less than that of the established hover gain
due to aerodynamic forces present in forw a rd flight.
If you’re using a dual rate gyro, adjust the gain so that you’re
using “higher” gain setting for hover and the “lower” gain setting for
f o rw a rd flight.
It will also be necessary to confirm the direction the gyro
compensates when the body of the helicopter is ro t a t e d .
To do this, turn the radio system on and suspend the helicopter
by the main rotor head. Next, move the rudder stick to the right and
watch the direction that the tail rotor servo arm travels. Now while
watching the tail rotor servo arm, rotate the body of the helicopter
c o u n t e rclockwise. The servo arm should move in the same dire c t i o n
as when the rudder stick was moved to the left. If the arm moves in
the opposite direction, reverse the gyro and re - t e s t .
