WING ASSEMBLY 

 
Remove the tape from the servo wire pull string at 
the center of the wing. Work the string through the 
exit hole in the wing bottom and secure. 

 

Measure the dihedral brace, locate and mark its 
center. 

 

 
Trial fit the dihedral brace in its box in both wing 

panels. The “V” shape of the brace points down to 
produce positive dihedral. The brace should have 
a snug fit, sand lightly if necessary.  

 

The following steps must be done quickly before 
the epoxy has time to set up. Read the procedure 
and gather the materials before starting. 
 

Mix a small amount of 30-minute epoxy. Spread 
the epoxy in the dihedral box top, bottom, and 
sides about 1 inch in on both wing panels. The 
snug fit of the brace will push it down the box.  

 

Apply epoxy to one half of the wing spar and slide 
it into position. Spread the epoxy that oozes out 
over the wing mating surface as well as the other 
half of the wing spar. Slide the other wing panel in 
place, wipe off the excess epoxy with a paper 
towel moistened with alcohol.  

 

Stretch masking tape across the joint in such a 
way as to apply pressure to the joint. 

DO NOT 

DISTURB THE WING UNTILL THE EPOXY HAS 
FULLEY CURED.
