18. Use a hobby knife and #11 blade to remove the
covering for the ignition switch. Mount the switch
using the hardware provided with the switch. Route
the leads from the switch to the front of the fuselage.
19. Use a hook and loop strap to secure the ignition
battery to the top of the engine box. Connect the
leads from the switch to the battery and ignition
module. Secure the leads using tie-wraps so they
don’t interfere with the operation of the engine.
Note: The suggested muffler includes an option for a
smoke system. The installation of the components for a
smoke system is up to the discretion of the modeler and is
not covered in this manual.
Note: Use the 4-pin balance connection (THP4P10E) on the
ignition Li-Po battery to make it easier to hook up a charger.
The extension can be left in place for accessibility. Use wire
ties to route the extension into the radio compartment near
the ignition switch.
20. Attach the muffler to the engine following the
manufacturer’s instructions.
21. (Optional: Manual choke) Slide a plywood choke
pushrod brace over the choke pushrod and glue
the brace to the fuselage using medium CA. Make
a 90-degree bend in the pushrod so it can be easily
operated from underneath the fuselage.
22. Use a 5/64-inch hex wrench to remove the four
cowl mounting screws with the preinstalled painted
washers and silicone tubing from their locations on
the fuselage. Attach the cowling to the fuselage. Use
a 5/64-inch hex wrench to tighten the screws that
secure the cowl to the fuselage. Use a tapered reamer
to make a 1/4-inch (6mm) hole in the side of the cowl
to access the mixture screws on the carburetor.
Note: The distance from the firewall to the front face of the
propeller drive washer is 6
1
/
2
-inch (165mm).
23. It will be necessary to remove the material from the
cowling to clear the exhaust system and to provide
cooling air to pass over the engine. Use hobby
scissors and a rotary tool with a sanding drum to
trim the cowling. Check the fit of the cowl over the
engine while making small adjustments to the fit of
the cowling.
Note: A small of canopy glue on the threads of the cowl
mounting screws will allow for easy removal, but help
prevent the screws from vibrating loose in flight.
