RUDRSTOP - Rudder Right Piro Stop Gain 

Menu items 

Description 

60 - 180 

(Default 100) 

The sensitivity of hovering and clockwise spin. The stop speed used for preventing the side wind, 
hovering shift and clockwise rotation. 

Suggestion 

The sensitivity is RUDRSTOP*TAILGAIN when the hovering and clockwise rotation stop. If the 
ability to prevent side wind is poor, hovering drifts rightward, or slow clockwise tail rotation 
stopping speed, increase the RUDRSTOP value. If the tail rebounds when stopping, on clockwise 
tail rotation, decrease the RUDRSTOP value. This value should not be varied greatly in any one 
instance. 

 

RUDD-ACC - Rudder Accelerate Delay 

Menu items 

Description 

0 - 15 

(Default 0) 

The higher the value, the longer it takes to reach the required Piro speed from stationary. 

Suggestion 

Increase RUDD-ACC on lag tail. 

 

RUDD-DEC - Rudder Decelerate Delay 

Menu items 

Description 

0 ~ 15 

(Default 0) 

The higher the value, the longer it takes for the tail to slow down. Used to smooth the deceleration 
of a piro when coming to a stop. 

Suggestion 

Increase RUDD-DEC on rebounded tail. 

 

RUDD-EXP - Rudder Stick Expo Curve 

Menu items 

Description 

-100 - +100 

(Default 0) 

Rudder expo curve relative to stick input.  

 

RUD-SENS - Rudder Stick sensitive 

Menu items 

Description 

50 - 150 

(Default 100) 

Fine tune the stick response to the actual piro rate. The higher the setting, the more sensitive the 
stick movement. 

9: TAIL TORQUE COMP 

Submenu Configuration Steps

 

PIT-COMP - Compensation of Collective Pitch to Tail Rotor 

Item 

Description 

-100 - +100 

(Default 0) 

A change in collective pitch will cause a change in the head speed of the main rotor, as well as 
causing a tail deviation. Adjust the 

PIT-COMP

 value until this torque change can be offset 

completely. If the torque change causes tail deviation counter-clockwise, compensate with 
rightward rudder direction input, i.e. compensate reversely rudder direction input. 

Identification of 

Compensation 

Direction 

Turn off brushless motor power or engine throttle, push the collective pitch stick, adjust PIT-
COMP value, check if the compensation direction of collective pitch to tail rotor is correct.
