Throttle Trim Lever Function

Hovering Throttle Lever

Throttle Curve Exponential

H-24

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 power when the flight

mode switch is in the Normal mode. The throttle trim lever

has no effect on flight modes 1, 2, 3, 4, or in throttle hold.

Note

: Making changes to the throttle trim lever does

not change the input values for any of the points on

the throttle curve; it merely makes adjustments to the

engine idle speed position.

The Hovering Throttle lever increases or decreases the

engine output power for the middle three points set for

the throttle curve. As shown in the figure below, use of

the hovering throttle lever shifts the curve upward or

downward parallel with the original curve. Therefore,

operation of the hovering throttle knob does not cause

any change to the original settings of the throttle curve.

The throttle trim range will affect the throttle curve as

shown. The adjustable range of output using the hovering

throttle lever is approxi/-15 points as shown in

the diagram below.

Note

: The Hovering Throttle has no effect on flight

mode switch positions 1 and 2.

With the X9303 2.4 system, individual throttle curves

are selectable to be either straight (linear) or curved

(exponential) setting. With the exponential function on,

you will notice that any sharp angles of the throttle

curve will become more “rounded” or “smooth”,

creating more equal throttle servo movement during

the entire curve range.

Accessing the Throttle Curve Exponential
