If you encountered oscillation on any axis during the initial flight, turn down the gain a little
for that axis. Then go through the following steps:
Increase the Rudder pot setting by about an “hour” (15°).
Take off with stabilization OFF. Turn ON at a safe height with the model in level flight.
Watch for oscillation on the yaw axis (“tail wag”). Do a shallow dive to pick up speed
and again watch for oscillation.
Land and adjust the rudder pot as required. If there was no oscillation, even when
diving, turn the pot up another “hour” or so. If there was oscillation, turn the pot
down roughly “half an hour”.
Take off and retest. You’re aiming to set the pot fairly close to the gain that just
produces oscillation in normal flying.
When satisfied, go through the same procedure for the elevator pot.
Finally follow the same procedure to set the aileron gain pot.
Many people find that on typical models the rudder gain can be quite high, while aileron
and elevator end up in the range of 9 o’clock to 2 o’clock. However, the settings vary with
factors such as model design, flight speed and control setup.
Note: It’s best to do the initial setup and tuning in fairly calm conditions to avoid
confusing stabilizer-induced oscillation with buffeting caused by turbulence.
Once you have things adjusted, test the effectiveness of stabilization by flying in
windier weather, turning stabilization on and off. You should see a noticeable
improvement in smoothness with stabilization turned on.
Note: If you have an eight or more channel transmitter you can use Master Gain to help
speed up the process of adjusting the individual gains.
A More Detailed Look at the Stabilized Receiver and its Use
What a Rate Stabilizer Does.
A rate-gyro stabilizer compensates for external disturbances on all three flight axes: pitch,
roll and yaw. If your plane is disturbed by an external force (such as a thermal or wind
gust) then the gyro sends out a “shot” of opposite control on the appropriate axis using
ailerons, elevator or rudder (or elevons or V-tail if used). This will “even out” the flight path
and make flying in turbulent conditions much easier. The 7-channel stabilizer is designed
to stabilize while keeping interference with normal control to a minimum. To achieve this,
the amount of correction is automatically reduced for large Stick excursions. However, the
balance between on-board stabilization and transmitter control is a compromise. There is
always some stabilizing effect whenever the stabilizer is active. Consequently, if you need
maximum airborne response to stick inputs, the stabilizer should be turned off using the
Gear (stabilization) switch. It’s important to understand that the 7-channel Hyperion
stabilizer, unlike some more complex and costly units, does not contain any accelerometers
or other sensors to establish an absolute level or direction. The Hyperion does just what
most people need – smoothing out flight while leaving the pilot fully in control.
Number of Transmitter Channels
The minimum number of transmitted channels required to use the stabilizer with a
conventionally configured, electric-powered, three-axis plane is five. That covers the four
flight channels: Throttle (channel 1), Aileron (channel 2), Elevator (channel 3) and Rudder
