INSTALLING THE SPINNER.

    Install the spinner backplate, propeller and 

spinner cone.

            The propeller should not touch any part 

of the spinner cone. If it does, use a sharp 

modeling knife and carefully trim away the 

spinner cone where the propeller comes in 

contact with it.

5) Attach the speed control to the side 

of the motor box using two-sided tape 

and tie wraps. Connect the appropriate 

leads from the speed control to the mo-

tor. Make sure the leads will not interfere 

with the operation of the motor.

Speed control.

INSTALLING THE AILERON - FLAP 

SERVOS.

Servos.

Small weight.

Thread.

           

Because the size of servos differ, you may 

need to adjust the size of the precut opening in 

the mount. The notch in the sides of the mount 

allow the servo lead to pass through.

1) Using a small weight (Weighted fuel pick-

up works well) and string, feed the string 

through the wing as indicated.
