4. Mix up a small batch of 5-minute epoxy and coat the
ignition tray tabs and the corresponding slots at the top of
the firewall. Install the tray. Use the two triangle stock pieces
to help secure the tray. Glue the triangle stock to the outside
of the tray between the tray and the firewall.

5. Use the template at the back of this manual to cut holes
in the fiberglass sub-cowl near the upper left corner (2 o’clock
position) for the ignition switch and the battery charge jack.
Position the template so that the rear cut line of the template lies
over the aft edge of the sub-cowl. This will allow enough room
for the switch on the back side. Note: Positioning the switch
here is important so that it is away from heat and gasoline.
Install the ignition switch and the charge jack. Connect the
ignition battery to the switch and the switch to the ignition unit.
Secure both of these connections with heat shrink tubing.
❏
6. Cut an access hole in the sub-cowl and pass the spark
plug lead through it. Connect the lead to the spark plug.
❏
7. Connect the remaining wires for the ignition unit.
Secure each connection with heat shrink tubing. Bundle the
wires together and secure them using small tie wraps.
FINAL ASSEMBLY
Radio Installation
To complete the radio installation, you will need three
Y-harnesses for the top and bottom wing aileron servos. If
you have a computer radio that has mixing functions, you can
use only two Y-harnesses and group the upper wing servos
on one channel and the lower wing servos on another.
