REDWING RC 50CC EXTRA

•Prepare the rudder servo by installing the 

grommets and inserts. 

 

  

 

 

 

 

 

 

 

 

•Drop the servo into place and drill for the 

servo screws 

with a 1/16” 

drill bit.   

 

 

 

 

 

•Remove the 

servo and 

thread a 

servo screw in and out of each hole. Then apply 

2 drops of thin CA to each and allow the CA to 

soak in and fully cure.   

 

•Install the servo with the output to the front of 

the fuselage 

and center 

using the 

radio. 

  

 

 

 

 

 

 

•The pull-pull cables are pre-installed by the 

factory with the crimp sleeves left loose.  Install 

the ball links to the threaded pull-pull ends for 

both the servo and the control horn.  

NOTE:

 Make sure the ball link is threaded in the 

center of the adjustment range (about ¾ of the 

thread) to allow even adjustment. 

 

• Secure the servo end of the cables first and 

install to the servo horn to the servo.
