e pair of wheels  

       

 One pair of wheel pants

 Slide wheel cuffs onto the main gear. 

 Insert nylon spacer onto wheel axel, then wheel.  

    When putting collars on make sure the wheel can 

    rotate freely. We also recommend using lock-tite 

    on set screws to prevent collars from becoming  

    loose. 

 

 Insert wheel axel onto main gear, on the back size use supplied washer and nut. Only 

thread in the nut until wheel pant in slipped between the axel and main gear. Once 
wheel pant is properly aligned tighten down nut while holding axel. 

 

 Install landing gear on fuselage using the supplied 3mm screws and washers. 

 

 With the main gear on, it is time to set the landing gear cuffs.  First, cut a slit along the 

neoprene tubing and slide the tubing onto the top edge of the gear cuffs, where the 
cuffs will meet the fuselage.  

  

 Next, take some Goop glue and apply it to the landing gear where the bottom of the 

cuffs meet the gear.
