Chapter 3 

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: 

 

Main gear 

 

One pair of 4.5” inch wheels 

 

One pair of wheel pants 

 

One pair of wheel pant cuffs 

 

One pair of Dubro axles  

 

Four wheel collars 

 

Hardware pack marked “wheels” 

 

Fuselage 

 

Rudder 

 

Tail wheel assembly 

Not Provided:

 

 

½” and a 9/16” inch wrench  

 

Blue loc-tite  

 

Allen wrench for wheel collars  

 

White wood glue such as Elmer’s or Epoxy  

 

 

 

 

Slide the wheel cuffs partway onto the  

 m

ain gear. 

 

 

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 strongly 

recommend the use of loc-tite on the setscrews 

of the wheel collars to prevent them from 

vibrating loose.
