linear output is caused by the loop servo's rotation. The exponential function can
eliminate the cross plate interaction in extreme times.

Throttle Hold
The Throttle Hold function is used to practice autorotation and is often use as a
safety switch for electric helicopters, holding the throttle in the off position. When
the throttle hold switch is activated, the throttle hold function holds the throttle
servo/ ESC in a specific position (normally low or off throttle) while all other servos
function normally. The throttle hold switch is also selectable. Switch selection
options include rudd D/R, gear, AUX2, aileron D/R or elevator D/R.

Throttle Curve
The T7AH-2400 offers three (3) separate throttle curves with five (5) adjustable
points per curve. This function allows you to adust the throttle curve to optimize
engine rpm at a particular pitch setting. Once the throttle curves are established,
each can be activated in flight using the 3-position flight mode switch. The flight
mode switch offersthree (3) selectable curves: N=Normal, 1=Stunt 1, 2=Stunt 2.
The N, or Normal, position should be used for starting the engine and 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 lever 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 throttlestick.The transmitter is factory preset to the throttle
curve as indicated by the solid line in the figure below. Individual points can be
activated and increased/decreased to suit your specific needs.
