2. Connect the rudder servos, elevator servos, and
throttle servo (if using a radio system that does not support
mixing, install Y-harnesses to the servos) to the receiver and
wrap it in 1/4" [6 mm] foam rubber. Also wrap the receiver
battery in foam rubber. Cut the included hook and loop
material into two equal lengths and use it to secure the
receiver and battery to the tray as shown (the same
instructions apply if using the optional aft receiver/battery
tray). Feed the receiver antenna through the plastic antenna
tube installed on the right side of the fuse.

3. At this point, the servo wires should be organized and
secured out of the way of the rudder pull-pull cables if using
the pull-pull system. One easy way to do this is to cut a few
#64 rubber bands into 3/4" to 1" [19 to 25 mm] long pieces
and use them as wire straps by gluing them to the side of
the fuselage with CA glue. For best adhesion, roughen the
area with sandpaper before applying CA.

1. Hold the cowl up to the firewall and mark where you will
be cutting out a cooling hole (exhaust exit hole). If installing
a glow engine, you will also want to mark the position for a
glow starter hole and a needle valve hole.
❏
2. Use a rotary cutting tool to cut the cooling hole and a
drill for the other holes you have marked. For a clean,
finished look, use a bar sander with 220-grit sandpaper to
clean up straight cuts, and sand the curved or round cuts by
hand. Test fit the cowl onto the fuselage and make any other
adjustments necessary to clear engine components.

3. Install the cowl with the long 3/32" [2.4 mm] allen key
using six 4-40 x 1/2" [13 mm] SHCS, six #4 flat washers, and
six #4 lock washers.
