2. Balance the propeller and spare propellers. Most .40-size
engines that will be used on this model run best with a 10 x 6
(10" diameter, 6" pitch) propeller, but refer to the manufacturer’s
recommendations that came with your engine. The Top Flite
Power Point Precision Magnetic Propeller Balancer (TOPQ5700)
is illustrated in the photo.

3. Mount the back plate of the spinner and the propeller to
the engine. Tighten the propeller nut “finger-tight,” then use the
appropriate-size wrench (10mm for most .40 engines) or a
crescent wrench to fully tighten the nut. 1/2-turn, plus 1/8 turn
should be sufficient. Note: Do not install the muffler until instructed
to do so.
❏
4. Prepare the fuel tank as shown in the photo, first by
inserting two aluminum tubes through the rubber stopper,
followed by the metal plates and the screw. Bend one of the
tubes upward so it will be near the top of the tank when the
stopper is inserted. This tube will be connected to the muffler
and serves both as an overflow line (to signify when the tank is
full) and as a pressure line to provide muffler pressure to the
tank. Connect the clunk to the other tube with the silicone tube
that came in the tank. Note that the silicone tube must be cut
to the correct length, so that when the tank is assembled, the
clunk does not contact the back of the tank. Otherwise, the
clunk could become stuck near the top of the tank, thus
discontinuing fuel flow.
❏
5. Insert the rubber stopper in the tank, then securely tighten
the screw. Shake the tank and listen for the clunk inside. If the
clunk stops making noise, the fuel line may be too long and the
clunk may have become stuck. Disassemble the tank and
shorten the fuel line as necessary.
❏
6. Install the fuel tank in the fuselage with the neck of the
tank protruding through the hole in the firewall. Make certain
you have installed the tank upright (with the pressure tube
inside the tank pointing upward).
❏
7. Test fit the 1/8" [3mm] plywood radio tray in the fuselage
over the four pre-glued mounting blocks. If necessary, use a
hobby knife to trim the notches in the battery tray so it will fit.
Note: The battery tray also keeps the fuel tank from shifting aft.
❏
8. Wrap the battery pack and receiver in 1/4" [6mm] R/C
foam rubber (if 1/4" R/C foam rubber is not available, 1/2"
[13mm] is suitable–it just takes up a little more space).
Securely mount the battery and receiver to the radio tray with
the Velcro strips included with the kit.
