WING ASSEMBLY 

 
Start by removing aileron and flap from 
packaged wing. Remove hinges. 
 
Place 2 pins in each hinge as shown and reinsert 
the hinges into flap and aileron. 
  
Attach flap and aileron onto wing panel, 
ensuring that they are properly aligned and the 
end spaces are minimal and equal. 
 

 

 
 
CAREFULLY apply THIN CA glue to each of 
the hinges, ensuring that the flap and aileron 
surfaces are FLUSH with the wing. 
 
Apply THIN CA to the bottom side of the hinges.  
 
Cleanup and CA spills with CA de-bonder or 
Acetone. Work quickly and have plenty of paper 
towels available as well as lacquer thinner. 
Leaving Acetone will cause a white film. 
 
HINT:  
 
Refer to the following picture. I used a VERY 
FINE bulb dispenser for the CA glue. This helps 
prevent accidental splashes onto the covering. 
 

 

 
Install both the flap and aileron servos with the 
screws provided with the servos. 
 
Use the pull string to work the servo wires 
through the wing and out the exit hole in the root 
rib. 
 
HINT: - Temporarily hook up your Aileron and 
Flap servos to your receiver and turn on the radio. 
This will help you center the ailerons and 
confirm proper operation of ailerons and flaps at 
this point rather than at final assembly time. 
  
Install the aileron and flap control horns. 
 
The aluminum horns included with this kit only 
require you to locate the proper position, drill 
one hole for the bolt and assemble.  
 
I would suggest using a drop of blue lock tight 
on the horn bolt to prevent it from becoming 
loose. 
 
(Remember- the flaps work differently to 
ailerons, so the horns for them will be mounted 
on the same side of the servo vs. ailerons which 
are usually mounted to the wing tip side of the 
servo). 
 
 Fabricate the control rods and attach to servos 
and control horns. 
 
HINT:- Use a small clamp to keep ailerons in 
neutral position while hooking them up, then use 
the clamp to keep the flap and aileron in line.  
 
The kit includes 4 strips of Ultra coat covering 
which may be used to cover the aileron and flap
