18: Throttle Curves

The 12X offers up to five (5) separate throttle curves with up to 

eight adjustable points per curve. This function allows you to 

customize the throttle curve to maximize engine performance 

at any particular pitch setting. Once the throttle curves are 

established, each can be activated in flight using the 3-position 

flight mode switch. If the additional 2 flight modes (numbers 3 

and 4) have been activated in the Device Select portion of the 

system mode, an additional switch will be used to activate these 

modes and two additional throttle curves will be available.

The flight mode switch offers three selectable positions:

•  N=Normal 
•  1=Stunt 1 
•  2=Stunt 2
•  Extra flight modes
•  3=Stunt 3 (optional)
•  4=Stunt 4 (optional)

Note

: The N (Normal) position is used as the hover 

throttle curve.

Positions 1 and 2 (Stunt 1 and Stunt 2) are typically used for 

forward flight and 3D maneuvers. Optional flight modes 3 and 4 

are also designed for use with aerobatic maneuvers and forward 

flight.

Note

: The throttle trim and hovering throttle trimmer 

are only operable when the flight mode switch is in the 

normal position. In the 1, 2, 3, 4 or hold positions, these 

two functions have no effect. Also, adjusting the hovering 

throttle trimmer and throttle trim has no effect on the input 

values of the throttle curve. Each of the eight points of the 

throttle curve is independently adjustable from 0–100%.

1.  In function mode use the Rolling Selector to highlight the 

THRO CURV function, then press to access. ALL SERVOS 

HOLD ? will be displayed. Press YES or NO to access the 

throttle curve screen.

2.  Moving the flight mode switch to the desired position 

will select the flight mode that will be programmed. The 

flight mode will be displayed in the upper left corner of the 

screen. 

3.  Move the Rolling Selector and highlight the desired throttle 

point to be adjusted. Press the Rolling Selector to access 

the point value, then roll the Rolling Selector to increase 

and decrease the point value.

4.  To set throttle curves for flight modes switch the flight mode 

to the desired position and the screen will change to that 

flight mode.

5.  Highlight the desired pitch point that you would like to 

adjust and press the roller. Rotate the roller to adjust that 

point on the pitch curve.

6.  To add a point move throttle stick to the desired position 

until STR appears on the left bottom of the screen. Pressing 

STOR will store a new point at that position.

Note

: To eliminate a point, press ERAS (bottom left of the 

screen) when the point is highlighted. 

7.  To exit the Throttle Curve function, highlight the LIST with 

the Selector and press.
