The aileron, elevator and rudder channel control surface angle can be switched in 2 steps

●The control surface angle is adjusted by each direction of the switch. The left and right (up and down) 

direction of each switch can be set individually.

This function makes operation more pleasant by changing the operating curve so that servo movement 

is sluggish or sensitive relative to stick operation near the aileron, elevator, throttle, and rudder neutral 

position. Adjustments can be made in 2 steps according to the control surface angle.

●The “-” side makes servo movement sluggish and the “+” side makes servo movement sensitive near 

the neutral position. Exponential is applied to entire throttle servo travel. When the “+” side is increased, 

the slow side becomes sluggish and the high side becomes sensitive.

●Setting corresponding to each rate of dual rate (D/R) is possible. (Except throttle) The direction of each 

switch and the left and right (up and down) direction of each channel can be set individually.

Switches A to H can be selected as the aileron channel, elevator channel, and rudder channel dual rate 

(exponential) switch.

●Default：Aileron：SwitchD ／ Elevator：SwitchA ／ Rudder：SwitchB
