 Step 12

Center the tail wheel. Use a 3mm x 6mm screw to secure 

the brass connector to the rudder wire.

 Step 13

Attach the tail wheel cover to the fuselage using three  

#2 x 1/2" screws.

 Step 14

Center the throttle stick and trim with both the receiver 

and transmitter on. Install the throttle servo arm in  

the neutral position as shown. Attach the clevis to the 

throttle servo arm.

 Step 15

Move the throttle stick and trim to low. Check to make 

sure the carburetor will move to the low position when 

operating the servo. Install a 3mm x 6mm screw to secure 

the easy connector to the throttle pushrod. Check the 

movement of the throttle to verify there is no binding at 

either low or high throttle. If there is, make the necessary 

adjustment to eliminate any binding. Install the throttle 

servo arm screw when complete.
