HELI 78
4.8 Throttle Curve (Function Mode)
The XP8103 offers three (3) separate throttle curves with five (5)
adjustable points per curve. This function allows you to
customize the throttle curve and pitch curve together to maximize
engine performance at a particular pitch setting. Once the
throttle curves are established, each can be activated in flight
using the three (3) position flight mode switch. The flight switch
offers three (3) selectable curves. N=Normal, 1=Stunt 1,
2=Stunt 2
The N, or Normal, position should be used for hovering.
Positions 1 and 2, or Stunt 1 and Stunt 2, should be used for
aerobatic maneuvers and forward flight.
Note: The throttle trim and hovering throttle knobs are only
operable when the flight mode switch is in the Normal position.
Thus, in the 1 or 2 positions, these two functions have no effect.
Each of the five (5) positions of the throttle curve are
independently adjustable from 0-100%. These five (5) positions
correspond to the position of the throttle stick.
The transmitter is factory preset to the throttle curve as indicated
by the solid line in the figure below. Individual middle points can
be activated and increased/decreased to suit your specific
needs.
