Neptune V2
ENGINE (
OR
MOTOR) POD:
34.
Test fit the engine pod’s carbon fiber tube into the round opening in the fuselage.
Pull all necessary wires (such as throttle servo’s lead and any optional onboard
glow plug driver) down through the carbon fiber tube and into the fuselage.
Then, with the engine pod and all related wires in position, insert the supplied
nylon bolt from inside the fuselage, through the carbon fiber rod
and snugly secure the bolt into the pre-installed blind nut inside the fuselage.
35.
Decide on your engine’s mounting position. (NOTE: When a glow engine is
mounted inverted or on its right side, with its muffler above the engine,
problems such as ‘hydro lock’ and ‘fouling of the glow plug’ are sometimes the
result. Therefore, we advise mounting your engine with its cylinder on the right
side, with the muffler below the engine, or with its cylinder straight up.)
36.
Once you have decided on your engine’s mounting position, mark and drill the
holes needed in the pod’s firewall, use the supplied bolts and blind nuts to
securely attach the engine mount to the firewall, mount your throttle servo, and
install and connect the throttle-control linkage. Decide where the fuel-tank’s
clunk and pressure lines need to be routed. Or, if you are using electric power,
use the mounting hardware supplied with your motor to solidly attach the motor
to the pod’s firewall. Mount your propeller onto the engine or motor.
37.
If necessary, fine-tune the engine pod’s angle to set the propeller at zero-degrees
left/right offset by gently twisting the carbon fiber tube in its mounting hole.
When you are content with the propeller’s angle, secure the pod into the fuselage by applying some
5-minute epoxy where the base of the carbon fiber tube meets the fuselage. (NOTE: We also recom-
mend you waterproof the opening at the top of the fuselage for the pod’s carbon fiber tube by filling
this gap with 5-minute epoxy, Shoe Goo or ZAP A-DAP-A GOO II.)
38.
If you are using a glow engine, maximize the supplied fuel tank’s usable capacity
by installing its vent line as near as possible to the top-center of the tank,
then install the fuel tank inside the engine mounting pod. (NOTE: The almost 11-
ounce fuel tank must be positioned on its side to fit
inside the pod’s fuel tank compartment; it may be
necessary to remove some wood
so the tank can fully fit down inside the pod’s
allotted fuel tank space, and to ensure the pod’s
hatch is able to fully close.)
39.
Connect the tank’s ‘clunk’ line to the carburetor
and the ‘vent’ line to the muffler. If you set up your Neptune for electric power, your power system’s battery and ESC may be able
to fit into the cutout for the fuel tank; if not, then mount both the battery and the ESC down inside the fuselage.
(NOTE: A power system that needs longer wires MUST gain that additional length by extending the three wire between the ESC
and motor; NEVER lengthen the wires between your battery and your ESC.)
40.
Mark and then carefully cut any necessary openings in the cowl for the engine’s cylinder head, exhaust, fuel tank vent line,
and/or cooling. Attach the cowl with the supplied wood screws.
CONTROLS & FINAL PREPARATIONS:
41.
To install an onboard glow plug driver and battery in your Neptune, you may need to slightly enlarge the opening in the base of
the pod’s carbon fiber mounting tube to accommodate the additional wiring between the fuselage and your engine.
42.
Install your radio receiver, connect the servos, and make any necessary adjustments to the servo directions and control throws.
43.
Position the wing over the fuselage and connect both aileron servos to the Y-cable and align and slide both of the wing’s
leading-edge pins into their corresponding holes in the fuselage. (NOTE: To help ensure the security of your servo wire to
Y-cable connections, we recommend that during flight you use an optional “servo extension safety clip” at each of the servo
wire to Y-cable connections.)
