CAUTION - This switch should be kept in the OFF
position until ready to run the motor. If you are not using
a throttle control, this switch alone will turn on the prop.
DO NOT PLUG THE BATTERY INTO THE SWITCH
HARNESS UNLESS YOU ARE PREPARED TO RUN
THE MOTOR. THE PROP IS CAPABLE OF SERIOUS
INJURY AND SHOULD BE TREATED WITH THE
UTMOST RESPECT!
D 10. Screw
a Nylon
Clevis (NYLON17) onto the
threaded portion of each
pushrod. Slide the pushrods
into the fuselage. The rudder
pushrod exits the top of the fuselage just in front and to the left
of the fin. The elevator pushrod exits the hole in the rear of
the fuselage. Snap the nylon clevises into the outermost hole
in the servo horns. The rudder pushrod goes to the left servo
and the elevator pushrod goes to the right servo. With the
control surfaces in their neutral position, use a felt tip
marker to make a small mark on each pushrod wire where
they cross the holes in the control horns. Remove the
pushrods from the fuselage and make a Z-bend in each wire
with the first bend starting where the marks are.
D 11. Cut any excess wire off 1/4" past the Z-bend and
reinsert the pushrods into the fuselage. Remove the nylon
control horns from the elevator and rudder and install the
horns onto the pushrods. Both pushrods should connect to the
control horns through the second hole from the inside. Rein-
stall the control horns to the elevator and rudder. Adjust the
nylon clevises until the control surfaces are at neutral when
the servo horn is perpendicular to the centerline of the
fuselage.
D 12. Pack the receiver in at least 1/4" of foam and install
it in between formers F2 and F3. The receiver antenna can run
down through the fuselage but try to route it as far away from
the servos and servo wires as possible. Allow the excess
antenna to trail from the fuselage. DO NOT CUT THE
ANTENNA!
D 13. The receiver switch can be taped to the top of the
Nylon Clevis
receiver or side of the throttle servo with double sided foam
tape. Because the canopy is so easy to remove, there is no
need for the switch to be accessible from the outside (this
helps cut down on aerodynamic drag and accidental shut-offs
during launching as well).
D 14. Soak the fuse bottom behind former F3 (about 2"
back) with CA. Allow the glue to cure while you cut the
"hooks" piece of Velcro (from VLCRSH02) in half length-
wise to make two pieces 3/8" x 1-1/2". Stick the two pieces
to the fuselage bottom as shown in the photo. Stick the
"loops" half of the Velcro to the forward portion of your 6 or
7 cell battery. See the fuse plan side view.
D 15. Prepare the 1/8" x 2" x 2" Balsa Battery Tray
(SPECF16) by soaking one side with CA. Allow the glue to
fully cure and then install it in its slot by first putting it down
into the fuselage in one slot and then carefully pulling it up
into the other slot. The surface with the CA coating should
be facing up. DO NOT GLUE YET - we won't glue this tray
in position until after we have balanced the airplane. Use the
remaining pieces of Double Sided Foam Tape to slick the
Receiver Battery to the tray. If you are using a larger (500
mah) battery that won't fit on the tray, you can skip this step
and just stick the Rx battery to the 6 or 7 cell battery with
double sided tape or velcro. The only drawback to this is you
will probably have to remove the wing to change flight
batteries.
D 16. Hook up your radio system and test the operation of
all controls. The controls should move smoothly without any
binding or looseness.
