5.

 

Note that you do not attach the wheel until the rudder is installed to the fuselage.  

This happens after the rudder is covered.   

6.

 

Press the tailwheel wire into the front of the rudder ½” from the bottom.  Wrap Tyvek 

(the white fiber paper) around the wire and secure with thin CA. 

  

 

Assembling the Wheel Pants and Landing Gear 

1. 

You will need to glue the wheel pants pieces together.  Below is a photo of all the 

pieces in the order that they are assembled. One side is assembled right to left, the 

other side is assembled left to right.  The 1/16” ply is inserted into the second 1/16” 

balsa sheet. 

 

2. 

The parts can be glued with thick CA or wood glue. Try to get them reasonably well 

aligned.
