3) Press either the MODE key OR the END key to scroll through the function menus. 

Continue pressing the MODE or END key until the normal throttle curve (N-TH) 
menu appears on screen.

4) The LCD screen will contain the throttle curve point indication (left side of screen), 

as well as the current throttle curve value, expressed as a percentage of travel, on the right side of the 
display. 

Note: Point 1 is shown initially which is throttle stick all the way downward (slow) position.  Point 5 is 
throttle stick all the way upward (hi) position.  

  Press the DATA INPUT lever upward to increase the percentage of servo travel for the respective point on 

the throttle curve.  Press the DATA INPUT lever downward to decrease the percentage of servo travel for 
the respective point on the throttle curve. 

5) Press the SELECT button one time to bring up the point two (2) throttle curve adjustments.  Again, use the 

DATA INPUT lever to adjust the values accordingly.

6) Repeat the previous steps to set the normal throttle curve point values for the remaining three (3) points. 

7) Press and hold the END button to exit the programming mode.

This curve is utilized to best match the blade collective pitch to the engine RPM for consistent load on the 
engine.  Pitch curve can be adjusted from 0-100% each point.  This normal pitch curve creates a basic curve 
for hovering.  Use this function together with the normal throttle curve to obtain the performance you desire.  

While each helicopter manufacturer will have specific recommendations for your flying style, generally 
speaking, the points should be adjusted as follows:

 

@ Point 1- the collective servo is at the desired lowest point with the throttle stick at the lowest (bottom) 

position.

 

@ Point 2- the collective servo is at the desired point with the throttle stick is advanced ¼ of the way.

 

@ Point 3- the collective servo is at the desired point with the throttle stick advanced ½ way.

 

@ Point 4- the collective servo is at the desired point with the throttle stick advanced ¾ of the way.

 

@ Point 5- the collective servo is at the desired point with the throttle servo fully advanced.
