Throttle Curves
The mx-12 offers two (2) separate throttle curves with
five 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 two (2) position flight
mode switch.
The flight mode switch offers two selectable ranges:
Normal and Stunt. The Normal position should be used
as the hover throttle curve. The Stunt position should be
used for aerobatic maneuvers and forward flight.
Note:
The throttle trim and hovering throttle levers are
only operable when the flight mode switch is in
the normal position. Thus, in normal function it
will have no effect. Also, adjusting the hovering
throttle lever and throttle trim has no effect on
the input values of the throttle curve.
Each of the five points of the throttle curve are indepen-
dently adjustable from 0-100%. These five points corres-
pond to the position of the throttle stick. The illustration
below shows the normal throttle curve setting for the
dead slow position with throttle trim at default.

Accessing the Throttle Curve Function
1. Place the transmitter power switch in the ON positi-
on.
2. Press the
Down
and
Select
keys simultaneously
to enter the Function mode.
3. Press either the Up or Down key until THRO ap-
pears in the upper portion of LCD.
Note:
Use NORM for hover curves and STUNT for
aerobatics. We will concentrate on the hovering
curve during this example.
4. Press the
Select
key to select the point of the curve
you want to change.
5. Press either the (+) or (-) key to change the value of
the current curve point. The range of each point is
0-100% in 0,5% intervals.
Note:
In each curve, the factory setting indicates INH
for points 1 and 3. These values are 25% and
75% respectively if no value changes are made
to any other points. If any of the other points
have been changed while these points were
inhibited, the inhibited points will also change
to plot a smooth curve. If you want to keep this
from happening, press the
Select
key until the
display indicates P-1 or P-3 at the upper right
portion of the LCD. Press either the (+) or (-)
key to activate the points 1 (25%) or 3 (75%).
The values for each of these curves can then
be fully adjusted by pressing either the (+) or (-)
key.
6. To set curves for STUNT mode, press the
Select
to
highlight the NORM function, then press the (+) or (-)
key to select the STUNT function. Repeat Steps 4
and 5 to complete the procedure.

Throttle Time Settings
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 power when the
flight mode switch is in the Normal mode. The throttle
