Gas Engine Installation - Horizon Hobby Hangar 9 Ki-43 Oscar 60cc Manuel D'utilisation

GAS ENGINE INSTALLATION

 As with many scale warbirds, the Ki-43 Oscar has a short nose
moment. It maybe necessary to add nose weight depending on what
power system is used. Be aware of this when assembling and try
to keep all components as far forward in the fuselage as possible.
1. Place the mounting template on the fi rewall. Use low-tack tape to
hold the template in position. Use a drill and 1/4-inch (6mm) drill bit
to drill the four holes in the fi rewall to attach the motor.
 When using power systems other than the recommended
choices, we advise using the mounting template as a test
to ensure hole alignment before drilling the firewall.
2. Use the screws and standoffs to draw the blind nuts into the fi rewall
from inside the fuselage.
3. Use a drill and 9/64-inch (3.5mm) drill bit to drill the hole for the
throttle pushrod.
 The location shown is for the Evolution 62GX. Make sure to
properly locate the throttle tube when using other engines.

4. Secure the batteries for the radio system and ignition in the lower
section of the fuselage. Use hook and loop tape and hook and loop
straps to keep the batteries secure.
5. Use medium grit sandpaper to lightly sand the pushrod tube.
Remove any oils or debris from the tube using a paper towel and
isopropyl alcohol.
6. Slide the tube into the hole in the fi rewall. Leave 1/4 inch (6mm) of
the tube protruding from the fi rewall. Use medium CA to glue the
tube in place.
7. Use side cutters to trim the pushrod tube 3/16 inch (5mm) behind
the edge of the inner fuselage side.
8. Use a drill and 9/64-inch (3.5mm) drill bit to drill a hole in a mixing
stick. Cut the stick to a length of 1
rear support for the throttle pushrod tube.
