Aileron-to-Throttle and Elevator-to-Throttle Mixing
Setting the Desired Flight Modes for Cyclic-to-Throttle Mixing
H-31
When doing a roll, flip, or anytime hard-over cyclic is
used, the main rotor’s rpm can decay due to increased
loads. This can be compensated for through the use of
the AILETHRO, and ELEVTHRO mixing. By adding
a throttle value to these mixes, when Aileron or Elevator
Cyclic control is applied, the throttle is advanced to
compensate for the increase in loading to the engine.
A good starting value is between 10%–30 % in both
directions for both Aileron and Elevator. Final tuning
needs to be performed during flight-testing. A + value
increases throttle; a – value decreases throttle.
Accessing the Cyclic-to-Throttle Function
1. Place the transmitter switch in the ON position.
2. Press the LIST key to enter the Function mode.
3. Move the Rolling Selector and highlight the MIX-
THRO function. Press the Rolling Selector to access.
4. Highlight the desired value to be adjusted with
the Rolling Selector, and then press to open the
options box. Roll the Rolling Selector to adjust
the value as needed.
The X9303 2.4 allows you to select the specific Flight
modes when the Cyclic-to-Throttle Mixing will be active.
The factory default position is ON for all Flight modes,
which is not ideal in most cases. As mentioned above, the
Cyclic-to-Throttle mix is generally used for Stunt (Flight)
modes only, so it will be necessary to select the Cyclic-to-
Throttle Mixing for the desired flight modes.
5. Move the Rolling Selector to highlight the SW SEL
for each of the Cyclic-to-Throttle Mixes to be used.
6. Press the Rolling Selector to open the Flight Mode
options box. Highlight the desired flight mode to be
set (NRM, ST1, ST2, ST3, ST4, GER), then press
the Rolling Selector to turn the mixing on or off for
each of the active flight modes.
7. To exit the Cyclic-to-Throttle function, move the
Rolling Selector to highlight LIST, and press to exit.
