Landing Gear and Tail Wheel Assemblies 

 

 
Now that we’re ready for assembly, we are going to start with the main landing gear first.  You will need to 
locate the following parts to begin assembly. 

 

 

Place an “

” to ensure task completion: 

 

 

What you will need in this chapter for the main gear: 

 

Carbon Fiber main gear 

 

One pair of 4 inch wheels 

 

One pair of wheel pants 

 

One pair of Cuffs 

 

Black neoprene fuel tubing 2’ 

 

One pair of Dubro axles  

 

Four wheel collars 

 

Hardware pack marked “wheels” 

 

Fuselage 

 

Rudder 

 

Tail wheel assembly 

Not Provided:

 

 

½” Black neoprene fuel tubing  

 

½” and a 9/16” inch wrench  

 

Blue loc-tite  

 

Allen wrench for wheel collars  

 

White wood glue such as Elmer’s or 
Epoxy  

 
 

 

Prep the cuffs: slice the supplied black 
neoprene tubing lengthwise. Install on the 
cuffs around the edge of the large opening 
with the seam on the belly side. Glue from 
inside the cuff with thin CA. 

 

Temporarily slide the cuffs on the main 
gear, and then fasten the axles to the main 
landing gear with the lock nuts.  

 

Using your four wheel collars and wheels, 
center you wheels on the axles.  Place the 
collars as close to the wheels as possible but 
ensure the wheels still rotate freely.  Again, 
we don’t want the wheel to move from side 
to side and contact the wheel pants.  Also, 
we recommend the use of loc-tite on the setscrews of the wheel collars to prevent them from vibrating 
loose.
