Rudder-to-Throttle Mixing Aileron-to-Throttle and Elevator-to-Throttle Mixing
Setting the Desired Flight Modes for Cyclic-to-Throttle Mixing
H-30
H-31
During 540 stall turns and fast pirouettes, the tail rotor
absorbs power and the main rotor rpm decays. You can
compensate for this using the RUDDTHRO mix. By
adding a throttle value to this mix, when rudder is applied,
the throttle advances or reduces depending on the desired
change in rpm. A good starting value would be +15%
for R (right mixing) and -10% for L (left mixing). You
should perform final tuning during flight testing. A + value
increases throttle; a – value decreases throttle.
When doing a roll, flip, or anytime hard-over cyclic is
used, the main rotor’s rpm can decay due to increased
loads. You can compensate for this with the AILETHRO,
and ELEVTHRO mixing. By adding a throttle value
to these mixes, when Aileron or Elevator Cyclic control
is applied, the throttle advances 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. You should perform final tuning during flight
testing. A + value increases throttle; a – value decreases
throttle.
Accessing the Cyclic-to-Throttle Function
1. Turn the transmitter switch ON.
2. Press the LIST key to enter Function mode.
3. Move the Selector and highlight the MIX-THRO
function. Press the Selector to access.
4. Highlight the desired value to be adjusted, and then
press the Selector to adjust the value as needed.
The X9503 2.4 allows you to select the specific Flight
modes when the Cyclic-to-Throttle Mixing is 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 for Stunt (Flight) modes only, so
you need to select the Cyclic-to-Throttle Mixing for the
desired flight modes.
5. Highlight the SW SEL for each of the Cyclic-to-
Throttle Mixes to be used.
6. Press the 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 Selector to turn the mixing on or off for each of
the active flight modes.
7. To exit the Cyclic-to-Throttle function, highlight LIST,
and press to exit.
