Maxford USA Neptune V2 Instruction Manual

GLOW/ELECTRIC 60-INCH WINGSPAN

NEPTUNE — VERSION 2

INSTRUCTION MANUAL

Congratulations on your acquisition of Maxford USA’s Neptune Version 2 boat plane!

This Neptune V2 ARF boat plane is the improved version of our previous Neptune. Its new color scheme is
much brighter and more visible in the air and the wingtip floats are now a bright red color. The engine pod now
sits atop a carbon-fiber tube, and all the wiring that needs to go between the engine pod and fuselage now easily
fits through this tube. The engine pod is redesigned and now consists of three pieces: the cowl, the bottom piece
(to hold the supplied fuel tank and your throttle servo), and the pod’s magnetic hatch/top cover.

The V2 wing has a carbon-fiber wing rod in place of the V1’s wooden wing joiner. The V2’s two aileron
servos are now located safely inside the fuselage (mounted near the center of the wing). A special new
compartment with an optional hatch has been added to the nose. The hatch arrives out-of-the-box covered-over.
To access the compartment, simply cut the covering material around the edges of the hatch. This makes it easy to
use this compartment for your radio’s battery or to add any necessary weight to adjust your Neptune’s CG. It is
also the perfect location if you plan to install an onboard glow plug driver and battery in your Neptune.

These improvements contribute to the V2’s lighter weight (the ARF-weight of the V1 was 6 lbs 8 oz,
whereas the dry flying weight of the complete new V2 is only 6 lbs 2 oz).

We invite you to enjoy the pride of ownership and the joy of flying this high
quality balsa, carbon-fiber, fiberglass and light-ply almost-ready-to-fly aircraft.

IMPORTANT SAFETY PRECAUTIONS

TO PROTECT YOUR MODEL, YOURSELF & OTHERS

1. This product should not be considered a toy, but rather a sophisticated, working model that functions much like a full-scale

airplane. Because of its performance capabilities, this product, if not assembled and operated correctly, could cause injury to you
or spectators and damage to property. Maxford USA provides you with a high-quality, thoroughly tested model airplane kit with
assembly instructions. However, the quality and capabilities of your finished model airplane depend on how you build it, and your
safety depends on how you use and fly it. Any testing or flying of this model airplane is done entirely at your own risk.

2. Assemble the model airplane according to these instructions. We recommend that you do not alter or modify the model, as doing

so may result in an unsafe or unworkable model. In a few cases the instructions may differ slightly from the photos; in those
instances the written instructions should be considered as correct. If you have any question or concern about these instructions,
before you proceed with assembly of this product, contact us at [phone], Monday through Friday, except national holidays,
between 8:30 AM to 5 PM Pacific time.

3. It is your responsibility to install the R/C system and other components in such a way that this model airplane passes all applicable

safety/range tests and that the power system and controls operate smoothly and correctly.

4. Recheck the operation of this model airplane before every flight to ensure that all equipment is still operating correctly and that

the model has remained structurally sound. Also, before every flight check all clevises and other connectors; do not fly without
replacing any that you find damaged or defective.

5. If you are not an experienced R/C pilot or have not flown this type of model before, we recommend that you get the assistance of

an experienced R/C pilo t.

6. Throughout the lifetime of this model, use only the Maxford USA-recommended or same-sized engine or equivalent electric

power system and a new or well-maintained R/C radio system and batteries recommended by the maker of the engine (or motor)
and radio system.

7. LITHIUM BATTERY HANDLING & USAGE: WARNING!!

on-line information. Failure to follow all instructions could result in permanent damage to the battery, its surroundings, and bodily
harm! If you crash this model airplane, check for battery damage. Do NOT use or charge a damaged Li-Po battery.

ONLY use a Li-Po approved charger.

(NEVER use a NiCd/NiMH charger!)

ALWAYS set the charger’s output to match the battery’s

voltage and mAh ratings.

ALWAYS charge through the battery’s “charge” connector.

(NEVER charge through the “discharge” leads.)
ALWAYS charge in a fireproof location.
NEVER place on combustible materials or leave unattended

during charge or dischar ge.

8. While this kit has been flight-tested to meet or exceed our rigid performance and reliability standards in normal use, if you plan to

perform any extremely high-stress flying, such as racing or advanced aerobatics, or if you plan to install a larger engine (or motor)
than specified, you (the buyer or user of this product) are solely responsible for taking any and all necessary steps to reinforce the
high-stress points and/or substitute hardware that is more suitable for such increased stresses.

9. This model includes fiberglass and carbon-fiber reinforced plastic parts that may require some cutting or sanding. Carbon-fiber

and fiberglass dust may cause eye, skin and respiratory tract irritation. If you ever grind, drill or sand such parts, always wear
safety goggles, a particle mask and rubber gloves; never blow into such a part to remove fiberglass or carbon-fiber dust, as the
dust may blow back into your eyes.

If you use LiPo batteries, read the battery’s instruction sheet or

NEVER charge a LiPo battery in excess of 4.2V per cell.
NEVER discharge a LiPo battery below 2.5V per cell.
NEVER allow battery temp. to exceed 150° F (65° C).
NEVER charge at a current greater than 1C (for example, in

the case of a 900 mAh battery, that’s 0.9 amps).
NEVER trickle charge.
NEVER disassemble or modify pack wiring in any way or

puncture cells.
KEEP BATTERIES OUT OF CHILDREN’S REACH
