The unique open-stick assembly 

provides fully adjustable stick tension 
"feel". Turning the tension adjustment 
screw clockwise will soften ( decrease 
the tension ) the feel of the control stick,
(fig 4).

CP-variable resistors improve 

the neutral characteristics and 
resolution of the servo positioning.

All of the molded parts are 

fabricated from high-grade
polycarbonate that is unaffected by 
temperature and humidity.

Turn with a Phillips
screwdriver
The spring becomes

5. Operation & adjustment

A. Control stick length & tension & trim lever adjustments

The length of the nonslip control sticks can be adjusted to suit the requirements of the 

operator. (fig-5)

The trim lever on each control stick is used to correct ( trim out ) flight 

characteristics. After the initial test flight note the positions of the control surfaces that 
required trim. Next center trim levers, turn off the receiver radio. Now adjust the control 
devices of the surfaces that required trim so that the surfaces are in the same position before 
the trim levers were re-centered. Turn on the receiver radio and recheck the control surface to 
ensure that all the corrections were applied in the correct direction.
