67. Insert two #2-56 blind mounting nuts into the holes in the laser-cut plywood wheel 

pant mounts. Press the nuts firmly into the plywood until their heads contact the 
wood. Use a little thick CA glue around their edges to keep them in place. As 
shown, the blind nut/plywood assembly will be glued to the inside surface of the 
inner wheel pant half. To correctly locate it's position, you must first drill the holes 
in the inner pant half for the #2-56 x1/2" mounting bolts. Slip one of the molded 
nylon landing gear mounts over the landing gear wire. Place the inner pant half 
over the landing gear axle, up against the upright part of the wire. Attach the same 
parts to the opposite axle. Use blocks or supports to prop up the fuselage on your 
work surface until it is level. The wheel pant halves should be resting flat on the 
work surface. With the airplane in this position, the location of the two holes 
required in each wheel pant half can now be made using a sharp pencil. Remove 
the pant halves and use a 3/32" dia. drill bit to drill the holes at the marks.

 

 
68.

 
Because the bolts are too long to allow free movement of the wheel within the 
wheel pant they must be cut to the right length. Simply insert the bolts through the 
nylon landing gear clip and through the wheel pant holes just drilled. Using a 
screwdriver, thread the bolts into the blind nuts, mounted in the plywood pant 
mount. Use a Dremel Tool with a carbide cut-off wheel to cut-off the exposed ends 
of the bolts, flush with the blind mounting nuts. Remove the bolts. Apply a little 5-
mInute epoxy to the inside face of the plywood pant mount but keep the glue away 
from the threads in the blind nuts.

Re-insert the bolts through the nylon landing gear mount and through the two holes in the inner wheel pant. Use your 
screwdriver to engage the blind nuts with the bolts, tightening the plywood pant mount in place against the inside surface of 
the wheel pant half. Let the glue cure before removing the bolts.

69a.

 
The outer pant halves can be glued in place to their corresponding inner halves. Apply thick CA glue around the edge of the 
inner pant half and carefully align and hold it in place to the outer half. Have a few small pieces of masking tape handy to 
help hold everything in position.

b.

 
Once the pant halves are joined, use a tapered sanding bit in your Dremel Tool to open up the bottom of the outer pant half, 
matching the wheel opening in the inner half. Apply thick CA glue to the wheel pant seams from the inside, going in through 
the wheel cut-outs. This seals and strengthens the pant seams.

c.

 
In order to properly support the wheel pants and keep them from twisting in flight, a hole must be drilled through the outer 
pant half for the axle. If you have access to a drill press, simply lay the pant flat and drill a 3/32" dia. hole through the outer 
pant half, using the hole in the inner pant half as a guide. Once the hole is drilled, mount the pants and wheels back onto 
the landing gear. The excess axle wire, protruding from the outer pant half, is now trimmed with your Dremel Tool and a cut-
off wheel, leaving about 1/32" or so exposed through the outer pant half. With the pants in place, test the fit and movement 
of the wheels. Make any necessary adjustments to create free movement and a good alignment.
 

 

 

 
70.

 
The wheel pants are now sanded for primer and painting. Before sanding, use a 
single edge razor blade to lightly scrape the pant seams. This quickly and 
uniformly smoothes the joint seams. Use 220 sandpaper to sand the wheel pants 
smooth, including the joint seams. The wheel pants are now complete.

 

 
71.

 
The 3/32" wire landing gear is now installed. The top part of the landing gear is 
inserted into the slots on each fuselage side, between the plywood landing gear 
supports. Test-fit the landing gear in place now. It should be a press-fit, with the 
wire snuggly in place between the landing gear supports.
