We recommend the use of an exhaust extension/diverter as shown, to direct exhaust away
form the airplane. Also note the vent line exiting the cowl, this is the crankcase vent for the
4-stroke engine, which can expel oil and needs to be vented outside as shown.
The cowl is mounted onto the fuselage with 4 wood screws. These screws go into the small plywood
squares on the front inside of the fuselage. The following procedure is helpful to be sure the wood
screws hit the plywood squares. Install the canopy hatch
(if the canopy hatch is not installed when
you fit the cowl, it may be impossible to fit the canopy hatch after the cowl is installed!).
Tape small pieces of paper over the plywood cowl-mounting tabs as shown below. Install the cowl and
align. Use the small pieces of paper as guides to make holes in the cowl and install the wood screws.
