The X9503 2.4 offers two different types of Gyro Gain
Sensitivity Adjustments: manual or automatic. This
feature gives the user the choice of selecting gyro
sensitivity through the rudder dual rate switch (AUX-2) or
automatically through the flight mode switch. The Gyro
Gain function allows you to have 2 different gyro gain
settings in Manual (RUDD D/R) mode, and 3 separate
gain settings in AUTO Mode.
If you select manual mode (RUDD D/R), you must use
the Rudder D/R switch to make gain changes.
If you select Auto mode, the Gyro gain is automatically
changed by linking directly to the Flight Mode switch.
If you do not intend to use this function, leave this
operation at the factory default position (OFF).
1. Turn the transmitter ON.
2. Press the LIST key to enter the Function mode.
3. Using the Selector, highlight the GYRO SENS function
then press to access.
4. Highlight INH with the Selector, and then press to
open the options box. Highlight the desired function
type Manual (RUDD D/R) or AUTO, then press the
Selector to select.
5. Highlight the function to be adjusted.
6. Press the Selector to select the gain position to be
adjusted, and then roll the Selector to increase or
decrease the gain values as needed.
7. If you select AUTO mode after setting the gain
values for positions 0, 1 and 2, move the Selector
to highlight the mode positions (NORM, ST-1, and
ST-2), and select the gain position (value) for each
mode.
8. To exit the Gyro Gain function, move the Selector to
highlight LIST, and press.
Connect the gain lead to the AUX2 channel of the receiver,
and the black connector to the rudder channel.
Note: This function is designed to be used only
with gyros that have in-flight proportional gain
adjustment capability. Single and dual rate gyros that
use a potentiometer to adjust the gain cannot utilize
this function.
The X9503 2.4’s Cyclic-to-Throttle function corrects any
under- or over-speeding of the main rotor resulting from
load changes placed upon the engine when an Aileron,
Elevator, or Rudder control is given.
Mixing – Cyclic-to-Throttle Mixing
The most common use for Cyclic-to-Throttle mixing is for
Stunt Modes 1-4, allowing the main rotor rpm to remain
consistent throughout aerobatic and 3D maneuvers. It is
not necessary to use Cyclic-to-Throttle mixing in Hover
(Normal) mode since control inputs are generally small
and much less aggressive.
Note: If using a Governor for rpm control, it is not
necessary to use the Cyclic-to-Throttle Mixing,
and all values should be left at the factory default
position (0%).
