35. Mount your muffl er of choice to the engine. We
used the SlimLine ™ Pitts style muffl er. This muffl er

36. Locate the plywood ignition module / battery tray.
Mount your ignition battery to the bottom of the tray
and the ignition module to the top of the tray. Place a
piece of foam between each of them. Secure them to
the tray with #64 rubber bands. Install the plastic sleeve
with the engine over the spark plug wire.
❏
37. Place the tray on the top of the fi rewall box. Drill
a 1/16" [1.6mm] hole through each of the mounting
tabs into the plywood box. Secure the tray with four #2

the screws vibrating loose you may wish to consider
applying some silicone on the bottom of the tray. Should
you need to remove the tray you can easily cut the
silicone, freeing the tray.

with the switch. Glue the switch mount to the fuselage
as shown in the picture in the next step.
