Install the Engines

:

❏ ❏

5. Place the engine on the mount, and secure it

using four 3mm x 18mm self-tapping screws.

Install the Mufflers:

❏ ❏

6. Install the muffler onto the engine using the

screws that were provided with your engine. It may be
necessary to slightly trim the engine nacelle to provide
a 1/4" (6mm) gap between the muffler and the engine
nacelle side. 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 need to shorten the fuel lines for a more direct
routing. Make sure that the lines are not kinked during
the routing, as this will restrict fuel flow and will reduce
engine performance significantly.

Attach the Propellers:

❏ ❏

7. If necessary, enlarge the hole in the spinner

backplate to fit onto your particular engine. It is best to

use a prop reamer for this procedure. Install the spinner
backplate, propeller, propeller washer and propeller nut
onto the engine. Position the propeller so it is horizontal
when the engine is against compression (the point at
which resistance is felt as the engine is rotated counter-
clockwise). This is a good practice to follow, because if
the engine were to stop running during flight, the
propeller will stop in this position, and the chances of
propeller breakage during landing will be greatly
reduced. The spinner backplate is properly positioned
when the propeller is almost touching the alignment
tabs on the spinner backplate. Use an adjustable
wrench (not a pliers) to fully tighten the propeller nut.

Install the Spinners:

❏ ❏

8. Test fit the spinner cone onto the spinner

backplate. Check to make sure that there is at least a
1/16" (1.5mm) gap between the openings for the
propeller in the spinner cone and the propeller. If not, trim
the spinner to provide the 1/16" (1.5mm) clearance
necessary. Once satisfied with the fit of the spinner
cone, attach the cone using the 2.5mm x 12mm self-
tapping screws provided with the spinner. Be careful not
to over-tighten these screws. They are threaded into
plastic which can strip out if they are over-tightened.
Repeat steps 4-8 for the other engine.

Install the Servo Tray:

❏

1. Locate the 1/8" (3mm) plywood servo tray. Test fit

the tray into position in the fuselage. Make sure it rests
