10. Remove the cowl and install the muffler for your
engine. We used the Bisson Pitts muffler (BISG4116) for the
O.S. 160. Make the appropriate cut out in the cowl to

the cowl and install the prop and spinner.

1. Cut the 10" [254mm] piece of Velcro ® into two 5"
[127mm] lengths.
❏
2. Install the receiver and battery as shown. Install a
piece of foam under the battery and receiver. Use the Velcro
to hold them in place. Plug all of the servos into the proper
channel in the receiver. Install a switch and charge jack into
the fuselage. Plug the battery into the switch and secure the
connector with a piece of heat shrink tubing, tape or other
method of securing the connectors to prevent them from
accidentally separating.
❏
3. Drill a hole in the bottom of the fuselage approximately
3/4" [19mm] behind the wing. The hole should be slightly
under-sized from the outer dimension of the silicone you
choose to use. Install a 3/4" [19mm] length of silicone fuel
tubing (not included) into the hole.
❏
4. From a servo horn, make a strain relief as shown.
Install the receiver wire through the silicone tube you
installed in the fuselage. Secure the end of the antenna wire
around the tail wheel with a rubber band.
