Install The Radio - GREAT PLANES ZERO Instruction Manual

2. Cut the muffl er cutout template for the Bisson muffl er
from the back of the manual and tape it into position as shown.
Mark the exhaust tube holes on the cowl, remove the cowl
and cut the holes.
3. Use a reinforced cutoff wheel (or other suitable tool
for cutting aluminum) to cut the exhaust tubes to a length
of 1-3/4" [45mm]. This length will allow the exhaust tubes
to protrude from the cowl far enough to direct most of the
exhaust away from the bottom of the model, but still allow
the cowl to fi t over the tubes. Deburr the ends of the tube
with a metal fi le or sandpaper and a hobby knife.
4. Use compressed air or warm, soapy water to thoroughly
clean all metal fi lings from the muffl er. Mount the muffl er to
the engine and mount the cowl to the fuselage enlarging the
exhaust cutouts as necessary to install the cowl over the
muffl er tubes.
5. Cut any more holes in the cowl necessary for the needle
valve, fueling line, glow plug igniter, etc.
6. Once all the holes are cut in the cowl, smooth any
rough edges and remove loose fi bers with 320-grit, then
400-grit sandpaper.
