Mount the engine
❏
48. Slide the throttle pushrod wire into the guide
tube and position the engine on the mount. Fasten
the engine to the mount using the four 3 x 15mm self
tapping screws.
Install the needle valve
❏
49. Line up the needle valve with the engine. Trim
away part of the fuselage side so that there will be
plenty of clearance to grip the valve with your fingers.
Coat the exposed wood with epoxy to seal it from fuel.
Install the needle valve into the carburetor.
Install the muffler
❏
50. Install the muffler onto the engine using the
screws that came with the engine. Attach the fuel
tubing from the “vent” in the fuel tank to the muffler
pressure tap. Attach the tubing from the “clunk” in
the fuel tank to the carburetor.
NOTE:
You may wish
to shorten the fuel lines for a more direct routing.
Make sure that the lines do not get any kinks which
could restrict fuel flow.
Attach the propeller to the engine
❏
51. Ream out the spinner backplate to fit on the
engine. Install the spinner backplate, prop, prop
washer, and the prop nut onto the engine. Position
the prop so it is horizontal when the engine is against
its compression (the point at which you feel
resistance when you turn the crankshaft counter-
clockwise). This is a good habit to get into when
installing props onto model airplanes. If the engine
quits during flight, the prop will stop horizontally,
therefore reducing the chance of prop breakage if you
are forced to land on rough terrain. Use an adjustable
wrench (not a pliers) to fully tighten the prop nut.
Install the spinner
❏
52. Trim the spinner cone slots so that there is at
least a 1/16” gap between the cone and the prop.
Once satisfied with the fit, attach the cone with the
screws provided. Be careful not to over-tighten these
screws. They are threaded into plastic which can strip
out easily if they are over–tightened.
Prepare the servos
❏
53. Install the rubber grommets and bushings,
included with your radio system, onto the four servos.
Refer to your radio manual for proper installation of
these items.
