ASSEMBLY

I. IF YOU HAVE A SUPER COMBO:
Skip to Section IV: ASSEMBLY on page 9.
II. IF YOU HAVE A COMBO PLUS:
Before performing the final assembly steps, it is necessary to
install your receiver and battery pack in the airplane, following your
radio system's instructions.
The connectors on the servos and switch harness are compatible
with Futaba "J" style radios. If you are using a different type radio, you
will need to either modify the connectors or obtain adapters. The
small polarizing ear on the servo and switch harness connectors can
be carefully trimmed off with an Xacto knife to allow it to be plugged
into JR, Hitec, and Airtronics (Sanwa) "Z"receivers. If you have an older
style Airtronics (Sanwa) radio, you MUST obtain adapters because the
polarity is opposite all other brand radios.
Remember to wrap the receiver and battery pack in at least 1/4"
thick foam. Route the receiver antenna out the rear of the wing open-
ing; if you wish, drill a 1/16" hole in the rear window for an antenna
exit. MAKE SURE you don't put any strain on the antenna wire com-
ing out of the receiver; have some sort of strain relief. Also, make sure
you don't lengthen or shorten the antenna; performance will be
affected. Continue the antenna wire to the top of the fin and hook
with a straight pin and a small rubber band. Any excess can just trail
out the back of the plane.

III. IF YOU HAVE THE TRTF VERSION:
A. Install the Main Gear
Referring to Sec. IV, Step A, secure the Main Gear in place. It will
help stabilize the fuselage as you work on it.
B. Engine/Cowl Installation
1. Test fit the two halves of the injection molded cowl together.
Trim away any molding "flash" that prevents a good fit. With the two
halves pressed tightly together, sparingly apply thin CyA glue along the
joint. Prevent runs by applying most of the glue from the inside.
2. Locate the three black nylon engine mount parts and the four
3X16 mm bolts. Position the engine mount plate on the firewall by
threading the fuel line coming from the fuel tank through the large
hole in the middle of the plate. Next, slip the bottom bracket on the
plate over the top of the nose gear assembly. You should now be able
to position the plate against the firewall and lined up with the four
mounting holes.
3. Place the left and right engine mount beams in position and
loosely hold in place with the four 3X16 mm bolts. The reinforcing
'web' on both beams should face upward and outward as shown.
4. Set your engine in place and adjust the engine mount beams so
they are centered on the plate and almost touching both sides of the
engine crankcase. Securely tighten the four bolts.
