Rudder Throttle Mixing
Rudder Throttle (R->T) mixing is used to maintain rotor
speed
so that altitude is kept constant when the rudder stick is
operated
in hover. The reason for this mixing is that when
rudder
is commanded, the tail rotor consumes a little more
power,
which reduces the power at the main rotor and the
helicopter
drops or climbs. For helicopters with normal rotor
rotation,
commanding right rudder (which requires more power)
should
also increase throttle slightly, while using left rudder
(requires less power) should decrease the throttle slightly.
R->T mixing is handy for hovering but may also be used in
540 ° stall turns, hovering eights, nose-in circles, Top Hats,
Pirouettes,
and other aerobatics. This function only operates
when
the NOR menu is selected.

Setting Up Rudder->Throttle Mixing

the
R->T window. To begin with, the function is already
activated,
but it's set to 0% on both sides so there is no
differential.

PMX1, PMX2 - Programmable Mixing
See ACGL PMX instructions on page 38. These instructions are
the
same for the two programmable mixers in the helicopter
menus.
2. To set the mixing amount for the left rudder, hold the rudde
r
stick to the left side (display shows L/U ), and press the Dat
a
Decrease key. Continue reducing the percentage until yo
u
reach about 10%. If for some reason you want a 0% setting
,
press the Active/Inhibit (Clear) key.
3. Input the mixing amount for right rudder by moving the
rudder
stick to the right (display shows R/D ), and press the
Data Increase or Decrease key to reach about 10% .
4. After you try these settings out, you can adjust them higher
or
lower to suit your machine. The signs shown here may
need
reversing depending on the way the servo is mounted.
5.
You may select which ON-OFF switch turns this function on.
See
the Switch Select instructions on P. 53 for information
on
how to select the ON-OFF switch.
6. Note that R->T mixing may only be set up, and only
operates,
in the NOR menu.
