4.8 Throttle Curve (Function Mode), cont.
Throttle Trim Setting
The throttle trim lever is only active when the flight mode switch
is in the normal position. The throttle trim is used to increase or
decrease the engine RPM to achieve a reliable idle when in the
Normal Mode. The throttle trim lever has no effect at position 1,
2, Stunt 1 or Stunt 2, or throttle hold.
Hovering Throttle Knob Setting
The hovering throttle knob increases or decreases the engine
output power for either the center point only (point #2), or
middle three (3) points, if activated, of the throttle curve. As
shown in the figures below, use of the hovering throttle knob
shifts the middle curve upward or downward. Therefore,
operation of the hovering throttle knob does not cause any
change to the high point and low point of the throttle curve.
