THROTTLE CURVE
Throttle Curve/Hovering Throttle
The throttle (CH3) servo response curve is represented by a graphic display on the right side
of the THROTTLE CUR VE screen. The response curve is divided into 11 equal segments by
12 dots or "Points" on the graphic display. Each of the 12 Points can be adjusted up or
down on the display to refine the shape of the curve.
The HOV-TH (Hovering Throttle) function trims the throttle servo position when the T/C
stick is near the center (hover) position. High and Low throttle servo limits are not affected.
Initial adjustment of the hover position can be made using the computer display. Later,
field adjustments can be made with the Hovering Throttle Knob on the transmitter. Throw
(trim authority) of the knob is adjustable.
