Rudder and Throttle, Servo Adjustments
1. Checking the servo rotation: With the radio transmitter
and receiver switched on, move the
rudder and throttle sticks checking that each servo moves in
the correct direction. If either
Servo moves in the wrong direction, reset the servo using the
appropriate reversing function on your transmitter.
2. Travel Adjust: Travel adjust settings are changed in
conjunction with the settings in the
Flybarless system settings.
NOTE: Try to get the mechanical set up as close as possible
to the values given in this manual and you will find that final
trimming will be much easier. Using the transmitter to correct a
poor mechanical set up will result in a model that is very
difficult to trim and fly.
3. Sub Trim Function. When the rudder stick and trim are in
their mid-position, make sure that the servo horn and tail
control rod are at 90°. If you cannot achieve the desired servo
arm position, use the sub trim function to make minor
adjustments.
NOTE: It is necessary to keep the sub trim values as close to
zero as possible to make final setting up simple.
Now that the radio system is fully installed the following
items require precise adjustment to achieve the best
results.
1. Dual Rates: If dual rates are available for the aileron,
elevator and rudder channels, then ensure they are all set to
the same position for high and low i.e. all up or all down. Either
switch position may be selected as low or high rate. Please
see your radio manual for further information.
2. Exponential settings: We suggest the exponential rate
settings for the elevator and aileron to remain at zero during
the initial test flights. When the model has been properly
trimmed, adjust exponential values to achieve the control feel
to suit you. When using a fast response gyro on the rudder,
the exponential value should be adjusted to approximately
40% to 60% to improve control response.
3. Sub Trim: We suggest that the correct settings be achieved
with the minimum use of this function. If the sub trim is used
for the final adjustments, the values should not vary by more
than +/- 10 from the neutral point. If the values need to be
greater than the neutral point , then reset the sub trim to zero
and recheck and/or re-adjust the control linkages.
4. Throttle hold function: When this switch is activated, the
throttle channel is set to stop while still leaving the control of
the collective pitch active. This is very useful when practicing
autorotation landings.
5. Flybarless system adjustment: ensure the Flybarless
system is setup per manual instructions. Incorrect setup can
cause serious damage to your helicopter and to you. If you
