1. Locate the four hardwood landing gear
blocks . Place them on you work bench exactly as
shown in the picture. You will notice that the front of
the block is square and the back of the block is angled.
You will also notice that there are a number of router
cuts in the blocks. Examine the picture closely to be
sure the blocks are just as shown in the picture.

2. Install the blocks for the right wing panel into
the opening as shown. If you have the correct blocks,
the angled end of the block should match the angle
of the opening in the wing.

3. Install one of the aluminum/fi ber landing
gear mounts between the landing gear blocks.
Temporarily secure the landing gear block and the
landing gear mount with six 8-32 × 2-1/2" [64mm]
socket head cap screws.

4. Repeat steps 1-3 for the left wing panel.

5. Double-check both of the landing gear block
installations to be sure they are correct. When you are
satisfi ed with the installation remove the bolts from the
right wing panel. Mix a 1/2 ounce [4 drams] of 30-minute
epoxy. Use an epoxy brush to apply a fi lm of glue to
the bottom of the landing gear mounting blocks and
to the rails in the wing as well as the sides of the box
the mounts slide into. Be careful not to get glue into
the blind nuts. If you get glue into the threads of the
bolts or blind nuts, it will be very diffi cult to remove the
mounting bolts. As a precaution, you might consider
applying a small amount of petroleum jelly or lightweight
oil to the threads of the bolts before installing them.
Place the wood blocks in position on the rails. Place
the aluminum/fi ber landing gear block between the
mounts. Secure the components to the wing with six
8-32 × 2-1/2" [64mm] socket head cap screws, #8 fl at
washers and #8 lock washers.

6. Drill a 7/64" [2.8mm] hole through each of the
two rear mounting holes of the landing gear. Insert two
#6 × 1/2" screws, #6 lock washers and #6 fl at washers.

7. Insert the landing gear wire into the hole in
the landing gear block. The axle of the wire must be
