To set points on the curve, start at the minimum throttle position which will be noted as point “L”. A point for 

“L” is not marked on the graph, but is the left-most end of the curve line. The vertical position of this point 

can be adjusted by moving the cursor to the RATE percentage, press 

ENTER

 then 

 or 

 as desired. 

Press 

ENTER

 when fi nished.

To set point 1 on the graph, advance the throttle stick until 

*

 shows next to “Point”. Find the desired throttle 

stick position and press 

ENTER

. A 

+

 symbol will be placed on the curve to mark this point.

Pressing 

 or 

 will adjust the vertical position of curve at this exact point. Adjust as desired.

Repeat these steps to set additional points on the graph as desired. A point for “H” is not marked on the graph, 

but is the right-most end of the curve line. The vertical position of this point can be adjusted by moving the 
cursor to the RATE percentage, pressing 

ENTER

, then 

 or 

 buttons. Press 

ENTER

 when fi nished.

To clear any point on the graph, place the cursor on the RATE percent, move the throttle stick until the 

graph’s vertical line intersects the point, press 

ENTER

 and then 

CLEAR

.

A switch can be assigned to toggle between the linear curve (for starting the engine, etc.) and the user-

defi ned curve (for forward fl ight, stunts, etc.). Select the switch on the CTRL line.

The exponential control of the user-defi ned throttle curve (but not the linear curve) can be active or inhibited. 
This will soften or make the transition of the throttle curve more smooth. Move the cursor next to the EXPO 

line and toggle between “ACT” and “INH”. Press 

ENTER

 when fi nished.

THROTTLE CUT

Allows the throttle channel’s output to be quickly moved to a user-defi ned position by fl ipping a switch. This 

is to reduce engine / motor power for safety reasons. Default setting is -100% (idle).

When setting up the model mechanically, make sure the carburetor is at full-open when the throttle stick 

is at full position. Use the trim to adjust the engine idle position. Move the throttle stick to idle position and 
turn the assigned throttle hold switch on and off repeatedly while changing the offset value until the servo 
stops moving.

Select a switch to control the throttle cut function on the CTRL line. Press 

ESC

.

The throttle cut function will only work when the throttle stick position is below the trig point. To set this point, 

move the cursor next to TRIG but do not press 

ENTER

. Move the throttle stick to the desired position that 

will trigger the throttle channel to move to the cutoff position. The graph will move accordingly as will the 
percent shown on the THRO line at bottom. Press 

ENTER

. The arrow on the left will now move and mark 

this selected trigger position.

Move the cursor to the CUT percentage, press 

ENTER

 and adjust this cutoff value by pressing 

 or 

 

to the desired position for the throttle channel’s output to move to when the throttle cut function is activated. 

This position will be marked by the arrow on the right. Press 

ENTER

 to confi rm this mark.

When the throttle cut switch is in the ON position and the throttle stick is positioned 

above

 the trigger mark, 

reducing the throttle stick to the trigger mark will automatically drop the throttle channel to the throttle cutoff 
mark. The throttle channel will remain in this position. To regain full control of the throttle channel, move 
the control switch to the OFF position.

NOTE:

 The method for setting the various following mixer screens is the same for each mixer. Refer to the 

instructions for the DIFFERENTIAL mixer screen for adjustment of all other mixer screens. Any difference in 
any one mixer screen will be noted accordingly. Normal wing mixing is the factory default setting. Depending 
on the mixes used and setup of the aircraft, it might be necessary to change the setting of the aileron, 
elevator, or rudder reversing settings to achieve the proper throw directions for the model.
