Helicopter Flight Trimming Chart
This procedure assumes helicopter is trimmed for hovering. Trimming must be done in near-calm conditions.
Repeat tests several times before making adjustments. If any changes are made,
go back over the previous steps and verify, or further adjust as necessary.
To test for...
1. RVMX mixing
- Up settings
(Part 1)
Fly the model straight and
level into the wind at 100 ft
altitude, lower pitch to 0°
Observe rotation as helicopter descends
A. No rotation
B. Model rotates counterclockwise
C. Model rotates clockwise
A. None
B. Add right rudder trim
C. Add left rudder trim
A. None
B. Increase UP RVMX mix
C. Decrease UP RVMX mix
A. No adjustment
B. Increase Down RVMX mix
C. Decrease Down RVMX mix
Observe rotation as helicopter
ascends
A. No rotation
B. Model rotates counter-
clockwise
C. Model rotates clockwise
Observe rotation as helicopter
ascends
A. No rotation
B. Model rotates clockwise
C. Model rotates counterclockwise
Bring the helicopter into
hover,
add full pitch and ascend
75 ft
Begin Down RVMX mixing
with same number as UP
mix. From inverted flight
(top of loop, or mid-point of
roll, or inverted part of split-S),
add full negative pitch
2. RVMX mixing
- Up settings
(Part 2)
3. RVMX Down

Setting Up The Revolution
1. Call up the revolution mixing screen by repeatedly pressing
one of the Up Down Edit buttons until the RVMX window
appears. The function is active with 0% mixing turned on.
Put the throttle stick to its idle position.
2. Now press the Data +In-
crease key. This will increase
the percentage of RVMX mixing
for the low side of throttle.
You may set a value of 0% to
100% for this side. If you wish
to return the mixing percentage to the default 0% value, press
the Active/Inhibit (Clear) key.
3. Move the throttle stick to a position above half-throttle, and
change the percentage number to suit.
4. Now verify that the rudder responds both the correct
direction and amount for travel on both sides when throttle is
commanded.
5. Set up the RVMX values for the other flight conditions (ST1,
ST2) by flipping the Flt. Mode (SW-3) switch and repeating
these procedures
to get to the aileron setting menu (the numeral 1 will be flash-
ing). Reverse the sign in front of the percentage with the Data
-Decrease key.
Now the swash should properly respond to aileron.
7. If all the servos tilt the swash
aft with up elevator stick, go to
the next step. If they tilt the
swash forwards, press the
Cursor Right key once to get to
the elevator setting menu
(the numeral 2 will be flashing). Now press the
Data -Decrease key until the sign is reversed in front of the
percentage value. Now the swash should properly respond
to elevator.
8. Double check that all three functions, collective, aileron, and
elevator, produce the desired result on the swashplate. Do
not set any SWAH values to 0% or you will disable the
response to that control!
