Great Planes Shoestring 60 ARF - GPMA1325 - Manual (Page 17)

10. Mount the muffler to the engine. A Bisson Custom
Mufflers #04061 Pitts muffler (BISG4061) was selected for the
O.S. .61 FX used on the model shown in this manual (the
muffler can be seen in the following photo). The muffler
supplied with the engine could be used, but this would require
trimming a significant amount of material from the cowl,
detracting from its appearance. Note: Approximately 1/16" of
the engine mount must be ground away to accommodate the
Bisson muffler. This poses no problem as long as the corners
are round as illustrated in the sketch.

11. Use the filler valve mount from a Great Planes
Handy Mounts set (GPMQ6000), or fashion a mount from
1/8" plywood (not included) for the fuel filler valve. A Great
Planes Easy-Fueler for glow fuel was used on this model
(GPMQ4160, not included with this kit). Use epoxy to
securely glue the filler valve mount to the firewall in a
location where the filler valve will be accessible outside the
cowl when it's time to fuel the engine.
❏
12. Use epoxy or fuelproof paint to coat the cowl
mounting blocks and the fuel filler mount.
❏
13. Cut holes in the cowl where necessary for the engine
exhaust, needle valve, glow plug igniter (or remote glow plug
hook up if used) and fuel filler valve.

1. Make the elevator and rudder pushrods by threading
two nylon clevises approximately 20 full turns onto the end
of two 36" pushrods. Connect each clevis to a large nylon
control horn.
❏
2. Slide the pushrods into the guide tubes through the aft
end of the fuse. Bend the pushrods as necessary so the
control horns will fit on the rudder and elevator. Drill 3/32"
holes through the rudder and elevator and mount the horns
with 2-56 x 5/8" screws and the nylon mounting plates on
the other side of the control horn.
