Throttle Curve (continued)
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 in flight modes 1 or 2 (Stunt 1 or Stunt 2), or throttle hold.
Hovering Throttle Rocker Setting
The hovering throttle rocker increases or decreases the engine throttle position for the center point only (point
#2) of the throttle curve. Use of the hovering throttle rocker shifts the middle curve upward or downward.
Therefore, operation of the hovering throttle rocker does not cause any change to the high point and low point of
the throttle curve but only affects the hovering rpm. The hovering throttle rocker only affects the throttle curve in
normal mode and has no effect on the curve in Stunt 1 or Stunt 2.
Exponential Throttle Curve Function
With the DX7 system, individual throttle curves are selectable to be either straight (linear) or curved
(exponential). To select an exponential curve, press the select key until EXP OFF appears on the throttle curve
screen. Next press either the increase or decrease key to activate the exponential feature (an “on” will replace
the “off” on the screen). With the exponential function ON, you will notice that any “sharp” angles of the throttle
curve will become more “rounded” or “smooth,” creating a smooth throttle servo movement during the entire
throttle curve range.
Idle Up
Normally, flight mode 1 and 2 are used to increase engine rpm below half stick for forward flight and
aerobatic maneuvers (idle up), and at this time any other trims are not active as the throttle will only
operate/follow the current throttle curve values.
Stunt 1 and Stunt 2
Note: Throttle curves are adjusted independent of the normal throttle curve. Simply select the
desired throttle curve by using the up or down keys.
