INSTALL THE RETRACTABLE
LANDING GEAR
IMPORTANT! The fi rst step in the installation of the
landing gear is to identify which blocks go into each
wing half. This is the most critical part of the landing
gear installation. If these blocks are not installed
properly the landing gear will not fi t properly into all
of the cut-outs in the blocks. Follow these instructions
exactly to insure the landing gear will fi t properly.
❏ ❏
1. Locate the four hardwood landing gear
blocks . Place them on your 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 the right side landing gear between
the mounting blocks. The landing gear fi ts between
the blocks best if you install it with the gear retracted.
Mount the landing gear and the blocks with six 8-32 ×
2-1/2 [64mm] socket head cap screws, #8 fl at washers
and #8 lock washers.
❏
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. Make sure
that the landing gear move smoothly in and out of
the wing. When you are satisfi ed with the installation
remove the bolts and the landing gear 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
blocks in position on the rails. Place the landing gear
between the mounts. Secure the components to the
wing with six 8-32 × 2-1/2" [64mm] socket head caps
screws, #8 fl at washers and #8 lock washers.

6. Repeat step fi ve for the left wing. Set the wings
aside and allow the glue to cure. Move onto the next
step after the glue has completely cured.
