RADIO INSTALLATION
RADIO INSTALLATION
Because of the small size of this plane and
the fact that the radio is imbedded in the wing,
installation is the most tedious part of the V-Bat.
We suggest that the radio be installed
before the wing halves are joined. This makes
it easier to get the wires routed.
❏
Begin by cutting the covering material from
the servo hatch area in the bottom of each wing
half. Cut the material in an “X” fashion from cor-
ner to corner. Then use a heat iron to seal the
material to the inner edges of the hatch area.
Trim away excess material.
❏
Next, use epoxy to laminate the two dihedral
braces together, keeping the holes lined up.
Clamp together as the glue sets. Wipe off
excess glue with a paper towel wetted with rub-
bing alcohol.
❏
Prepare your servos as shown, using your
longest servo arm and the “EZ” connectors fur-
nished.
❏
Install your receiver in the left wing.
There is a tube in the interior of the wing
which you may use for an antenna tube. In the
prototype, since our antenna was too long, we
simple taped the antenna to the trailing edge of
the wing and let the excess trail out the tip.
❏
Install the servo next. Notice there is a rec-
tangular hole in the root of the wing for the
cables to pass through. You may need to open
this hole up to get the connectors to clear.
❏
The servo is held in place with the furnished
plastic strap and two wood screws. You will
have to drill holes accordingly.
❏
Linkage to the elevon is with a threaded rod,
nylon clevis, and control horn.
❏
We chose to mount the switch in the rear
area of the opening. To gain clearance, we
have to remove the bottom switch cover.
❏
Once you are all done, the hatch is held in
place with a few pieces of clear tape or the
screws furnished. We had to do some trimming
on the prototype to clear the servo linkage and
the cables going into the receiver.
❏
Now, in the same fashion, install the servo,
its linkage, and the on-board mixer (if used) in
the right wing.
❏
Trial fit the dihedral brace in the wing. Trim if
needed.
❏
Epoxy the dihedral brace in the left wing half,
making sure the hole in the brace lines up with
the hole in the wing’s interior. Wipe away any
excess epoxy on the root of the wing.
❏
Route the battery pack cable next. It goes
from the battery compartment through the dihe-
dral brace and into the servo compartment in
the left wing half. Some trimming of material
may be necessary for clearance. You will need
a piece of 1/16” or smaller music wire to “fish”
the wire through the holes. Poke the wire
through from the servo compartment to the bat-
tery compartment, tape the battery connector to
the wire, and pull the music wire back into the
servo compartment. Hold your tongue right and
it will work!
