of oil to the pivot point on the hinges. This will prevent
the epoxy from adhering to the pivot point. Make sure
oil does not get on the gluing surface of the hinge.
If it does, clean the oil off with a paper towel square
dampened with denatured alcohol.

6. Mix up approximately 1/4 oz. [7.4cc] of 30-minute
epoxy. Use a toothpick to thoroughly apply the epoxy in
the holes in the fi n and rudder. Use the toothpick to get
the epoxy out of the opening of the holes in the rudder
and fi n so it doesn’t get into the hinge pin. Wipe away
any excess epoxy around the outside of the holes with
a couple of the small paper towel squares dampened
with denatured alcohol.
❏
7. Use the toothpick to apply epoxy to the ends
of the rudder hinges that go into the fi n. Insert each
hinge into the fi n and wipe away any excess epoxy
that squeezes out of the hole.
❏
8. Apply epoxy to the other end of the hinges. Join
the rudder to the fi n, pushing the hinges only about
3/4 of the way into the rudder. Use a toothpick to wipe
away any epoxy that squeezes out. Then push the
rudder the rest of the way in.
❏
9. Move the rudder left and right to align the hinges.
If needed, use a length of masking tape to hold the
rudder to the fi n. Allow the glue to fully cure.
INSTALL THE TAIL GEAR ASSEMBLY
We have provided instructions for the installation of the
fi xed tail gear assembly and the Robart retractable tail
gear. The two tail gears are interchangeable; you can
install the fi xed gear and upgrade to the retractable
gear later if you wish. Proceed to "Mount the Fixed
Tail Gear" or if you will be installing the retractable tail
gear skip ahead to, “Mount the Retractable Tail Gear”.
MOUNT THE FIXED TAIL GEAR
❏
1. Slide a 3.5mm wheel collar on the tail gear wire.
Insert the tail gear wire in the tail gear mount . Install
a second wheel collar followed by the steering arm
on the tail gear wire. Apply a drop of threadlocker on
three 3mm × 6mm machine screws. Secure the two
wheel collars and the steering arm to the tail gear wire
with the three 3mm × 6mm machine screws. Adjust
the location of the steering arm so that it is fl ush with
the top of the tail gear wire and perpendicular to the
tail wheel. Also, remove the two nuts from the top of
the tail gear, apply threadlocker and reinstall the nuts.
❏
2. Enlarge the holes in the steering arm with a 5/64"
[2mm] drill bit. Mount a 2-56 ball link ball to each arm
with a 2-56 nut and a drop of threadlocker.

3. Skip to step 6 in “Mount the Retractable Tail
Gear” and follow the steps for installing the pull-
pull cable.
MOUNT THE RETRACTABLE TAIL GEAR
