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, , Stunt 1 or Stunt , or
throttle hold.
The hovering throttle rocker increases or decreases the
engine output power for either the center point only (point
#), 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 affect the hovering rpm.

Exponential Throttle Curve Function
With the XP70 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 more
equal throttle servo movement during the entire throttle
curve range.
Idle Up
Normally, flight mode 1 and are used to increase
engine rpm below half stick for forward flight 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.
