 2. Without using any glue, test fi t the wing halves together 

with the plywood 

wing joiner

. Make sure the wings fi t  well 

with no gap. Make any adjustments necessary for a good fi t.

 3. Use 30-minute epoxy to glue the wings together with 

the joiner—be certain to coat 

all

 mating surfaces—inside 

the pockets where the joiner goes, 

all the way around

 the 

joiner and the ends of both wing halves. Use masking tape to 
hold the halves together and wipe away excess epoxy before 
it hardens. 

 4. After the epoxy has hardened, carefully peel off the 

masking tape. If necessary, use your covering iron to reattach 
any lifted covering back down to the balsa underneath.

MOUNT THE WHEELS AND LANDING GEAR

 1. Insert the right and left 

main landing gear wires

 into 

the wing so they will be angled forward.

3/32" [2mm]

3/32" [2mm]

 2. Holding a fl at landing gear strap over one of the gears 

in the wing, drill a 1/16" [1.6mm] hole into the bottom of 
the wing using the hole in the strap as a guide—note that 
the strap must be mounted at an angle so the holes will be 
no farther than 3/32" [2mm] from the wire. Otherwise, the 
screws will miss the hardwood rail inside. 

 3. Mount the strap to the wing with a 2 x 8mm Phillips 

wood screw. Holding the strap at an angle so the second 
hole will be no farther than 3/32” [2mm] from the front of the 
wire, drill the hole and install the second screw.

 4. Mount the other strap over the other gear the same way. 

Remove all the screws, add a drop of thin CA to each hole, 
allow to harden, and then reinstall the straps and screws.
