STICK TENSION: Silver screws on the
back of each gimbal are used to adjust the
stick tension. Turn the screw clockwise to
make stick tension more fi rm. Turn the
screw counter-clockwise to make stick
tension more light.
THROTTLE RATCHET: A silver ratchet
bar is mounted across the throttle gimbal.
For smooth throttle feel for helicopter use,
you may wish to remove this bar. Remove
both screws which hold the ratchet bar then
remove the bar.
DIGITAL STICK TRIMS
The trim controls for the four main
channels are digital. Holding the trim
lever will cause the servo output to move
repeatedly. Trim positions are visible
on the LCD’s home screen, and stored
into that respective memory. Changing
the model memory will also cause trim
settings to change accordingly.
For aircraft with glow engines, the precise
position of the trim lever is helpful when determining the engine’s preferred idle point. When the throttle
stick is above 50% full throttle it will not be possible to trim the throttle servo – even though the indicator
on the LCD will move.
The amount of servo movement for each increment of a digital trim can be adjusted as desired, as explained
in the TRIM STEP SETTING section on page 12.
