Neptune V2
44.
Snugly attach (but do not over-tighten) the wing-retainer screws in their blind nuts in the wing saddle mounting blocks inside
the fuselage. (NOTE: Some flying boat fans like to create an improved water seal at the wing-saddle by adding some
weather-stripping, such as M-D Building Products’ white ‘Rubber Weatherseal’ item #02576, available at many hardware
stores.)
45.
The included two pieces of triangular-shaped material may be used as strakes, but their installation is optional: If you do not
enjoy ‘drifting’ on the water during high-speed turns, use 5-minute epoxy to attach one strake at the center of the fuselage
immediately in front of the step, and attach the second strake immediately behind the step.
46.
Install the pod’s hatch (secured with rare-earth magnets), and add the supplied decorative stickers, if desired.
Congratulations! Assembly is finished!
SETUP AND ADJUSTMENTS
1.
The Neptune’s center of gravity (CG) must fall within 3¾-inches to 4½-inches (approx. 102 mm) back from the leading edge
of the wing. If necessary, move batteries and/or add weight to the nose or tail to ensure the CG is correct.
2.
Check the heat-shrink covering material’s joints and surfaces; if necessary, carefully use a dedicated covering-material iron
to secure the edges and to tighten any loosened areas. Recheck and retighten from time to time.
3.
Check/adjust servo centering, direction and end-point adjustments. When you pull the right stick toward you, the elevator
should deflect upwards; push the right stick to the right and the right aileron should deflect upwards and the left aileron
should deflect downwards; push the left stick left and the rudder should deflect to the left as viewed from the rear of the
fuselage. Review your radio’s instruction manual if you require assistance with any radio-related servo-adjustment questions.
4.
If you are using a Computer Radio: For initial flights set all linkages for near-max. possible deflections; then, soften the
aileron’s and elevator’s control throws by applying 60% exponential (use 30% exponential for the rudder).
Initial settings if you are using a Non-Computer Radio:
Low rates High
rates
Ailerons
..................................... +20 degrees (+3/8 inch) .......... +35 degrees (+1/2 inch)
Elevator ..................................... +25 degrees (+1/2 inch) .......... +30 degrees (+5/8 inch)
Rudder .................................... +25 degrees (+1 3/4 inches)
.... +30 degrees (+2 1/8 inches)
5.
Trim adjustments: The ailerons and rudder will probably require no adjustments (in all probability you will be able to leave
them centered, as assembled); however, be prepared to set the elevator trim depending on how slow or fast you fly. For
example, if you like flying low and slow around the lake, your Neptune’s elevator may require a bit of up-trim.
PREPARATION FOR TRANSPORT AND FIELD SETUP
1.
Unscrew and remove the two screws that secure the wing to the fuselage.
2.
Gently lift and slide the wing back, then lift it up and away from the fuselage.
3.
Disconnect the aileron’s Y-cable from each of the two aileron servos.
4.
To reattach the wings, reverse the above procedure. Be careful to firmly connect both aileron servos to the Y-cable (please
review the ‘safety clip’ note at the bottom of page 7), to align and slide both of the wing’s leading-edge pins into their
corresponding holes in the fuselage, and to snugly reattach (but not over-tighten) the wing-retainer screws into the blind nuts
in the wing saddle mounting blocks inside the fuselage.
PRE-FLIGHT CHECKS
1.
Double-check the security of the engine-pod, and make certain that all screws, clevises and other connections throughout the
air frame are secure.
2.
Double-check the control directions of the throttle, ailerons, elevator and rudder.
3.
As with all radio-controlled model airplanes, this model must pass the radio range ground check recommended by your radio’s
manufacturer, or you may not safely fly.
4.
Get into the habit of moving your transmitter’s throttle to minimum before turning ON your transmitter, and carefully break-in
and operate your engine or electric power system according to the manufacturer’s instructions.
