Governor
The Governor Screen supports adjustment of the engine
revolutions per minute (rpm) when using a Governor or throttle
limiter. Program governor values assigned to the flight mode
switch or another switch as desired. RPM values can be
adjusted in 0.5% increments. Make sure the governor and
receiver are connected. Assign a switch to governor control,
select the channel connected to the governor, then assign
values to available switch positions.
The governor and the gyro must use two different channels.
If the gyro function uses a channel, it will not appear in the
governor list. Values displayed on the screen are the corrected governor
values. 0% represents 1.500ms (or power off) with most
governors.
Flight Mode
The Flight Mode (F-Mode) Screen assigns switches for Flight
Mode and Hold. The Flight Mode default switch assignment
is Flight Mode–Flight Mode switch and Hold–Inhibited. Assign
Flight Mode and Hold to available switches as desired.
Swashplate
The Swashplate Screen supports adjustment of the amount and
direction of swashplate travel of the aileron, elevator and/or pitch
functions. Options vary with the Swash Type selected for a model
(see Swash Type). A value change on the Swashplate Screen
causes change to the overall travel of a function and not to
overall travel of only 1 servo or channel. For example, increasing
pitch values increase travel of all servos controlling pitch.
Swashplate values will vary among models.
You can use positive or negative Swashplate values as needed
for correct direction response of the helicopter.
1. Before making swashplate value adjustments in this screen,
make sure the servos move in response to controls in the
desired direction by “Reversing” in Servo Setup so that:
A. The aileron stick input tilts the swashplate to the right
and left.
B. The elevator stick input tilts the swashplate forward and
back.
C. The pitch/throttle stick input moves the whole
swashplate up and down.
2. Adjust each swashplate value (positive or negative) for cor-
rect overall swashplate travel.
3. Always enable Expo when using a standard rotating-arm
servo.
NOTICE: This Expo application delivers linear movement of
the swashplate from a standard rotary servo. When Expo is
inhibited, the standard servo’s arm moves on a curved path, with
decreased swashplate movement at the extremes of the servo
arm’s travel. Do not enable Expo when using a linear servo.
