The CA will “wick” into the wood and secure the 
hinge, only one drop is necessary

 
Use the same procedure for all the remaining 
control surfaces. Line up the edges carefully and 
apply one drop of thin CA to each side of the 
hinges. 

 

 

SERVOS / CONTROLS 

 
Install the servos in the servo tray following the 
radio manufactures instructions. Cut the throttle 
control casing 1/2-inch behind the fuel tank. 

 

Install two 6-inch pieces of fuel line on the tank 
carburetor and vent tubes. Install the motor using 
the four supplied screws washers and lock nuts. 
 
Make a “Z” bend at one end of the throttle control 
wire. Install the “Z” bend in the carburetor. Slide 
the other end of the throttle 

control wire through the outer casing and place the 
carburetor on the motor. 

Do not tighten

.  Bend the 

wire slightly till throttle operation is smooth and 
does not bind. 

 

Temporarily hook up the receiver and battery, 
power everything up and center all the servos. Pull 
the throttle trim to the off position and the throttle 
stick to idle. With the carburetor fully closed mark 
the location of the servo arm hole on the control 
wire.
