Comments: the Triton is a fun boat that will please
beginners and more experienced enthusiasts alike. There's enough
complexity and hop-up potential to keep things interesting for
the more accomplished modeler, but assembly is simple enough to
complete easily for all but the most inexperienced builder. The
Triton is satisfyingly fast right out of the box, is
impressively sized and handles well. It's an all-around winner
for a day of fun at the pond.

Hits
• Easy to build.
• High-quality materials used throughout.
• Good-looking graphics are racy without being toy-like.
Misses
• Motors run very hot.
• Instructions fail to mention that stuffing tube needs to be
filled with grease.

Mythical
Machine
A new offering from Academy (imported by Altech Marketing/MRC*) has just
the right blend of quick assembly (to get you on the water without
missing a soccer game), good value and satisfying performance to keep
you smiling. Given that three-pronged approach toward water-borne R/C
excitement, it's only fitting that the boat of which I speak is named
Triton. Care for a closer look?
THE KIT: The Triton's two-piece, ABS catamaran
hull is joined at the factory. A functional vacuum-molded stand is
supplied, and the kit's components are neatly bagged for easy assembly.
The manual is precisely illustrated and combines "actual-size" hardware
keys with simple icons to indicate repeated steps, such as the need for
lube, etc., to keep assembly moving quickly.
HULL CONSTRUCTION: The 30-inch Triton's
catamaran-type ABS hull is large enough to impress without being
unwieldy on the workbench. Since the upper and lower halves are already
joined, little building is required to ready the hull for the
installation of radio and running gear. A quick float in the bathtub
found the hull to be well sealed. The first step is to glue a pair of
gearbox plates, which are merely Popsicle-stick-size plastic doublers
designed to reinforce the hull for the gearbox's self-tapping screws
into the hull's forward compartment with the included solvent-type
cement. I found this glue to be quite aggressive—only a thin coat was
required. Two plastic pushrod guides are inserted through the transom;
the instructions call for CA to be used to secure them, but I epoxied
the pieces in place to ensure a gap-free fit. Rubber bellows are
provided to seal the rudder's wire pushrods (installed later) as they
exit the guides.
Installation of the drive system begins with the assembly of the gearbox
and stuffing tube. The composite plastic gearbox has a deep socket that
holds the stuffing tube perpendicular to its face, while a pair of
adjustable aluminum brackets secure the gearbox to the hull. Dry-fit the
stuffing tube into the factory-drilled openings in the hull. It's easy
to adjust the gearbox to sit squarely on its mounting rails while
maintaining the correct angle to mate it with the stuffing tube. After
you've properly aligned the components, tighten the gearbox brackets to
hold the adjustment, and epoxy the stuffing tube into place. Now slide
the drive shaft through the gearbox and into the stuffing tube, and
install a bronze bushing at each end of the drive shaft. The
instructions fail to mention that the stuffing tube should be filled
with grease, although there is a hole in the tube for just this purpose.
With the drive shaft in place, install the 540 motors, one on each side
of the drive shaft. The simple 1.5:1 reduction transmission uses a
24-tooth pinion gear on each motor to spin the drive shaft-mounted,
36-tooth spur gear; a snap-on cover seals the assembly.
Construction moves to the business end of the boat, where you'll connect
the molded rudder to a bracket that allows the depth of the prop and
rudder—as well as the angle of the assembly—to be adjusted. I installed
the plastic prop to the drive shaft with a metal drive dog and 4mm nut.
A "dogbone" mates the prop's drive shaft to the primary drive shaft via
a drive cup (an optional U-joint is available). To complete the hull,
aluminum combination trim tabs/turn fins are bolted to it through
plastic doublers. Since the mounting screws pierce the hull, I installed
them with epoxy to safeguard against leaks.
ELECTRONICS INSTALLATION: The Triton's forward
compartment holds a pair of stick-type batteries ahead of the
transmission unit. The molded cradle holds the packs tightly, and a few
squares of hook-and-loop tape (Academy's Magic Tape) are provided for
extra security. The packs are plugged into a mechanical speed control,
which is installed with the radio gear on a separate radio tray. The
Triton's design allows all the electronics to be installed with the tray
out of the boat, which simplifies assembly and also makes maintenance
easier. I bolted in two standard Airtronics* 94102 servos (included with
my CX2P radio) for throttle and steering duty, then rubber-banded the
receiver and battery pack into their molded bays. After powering up the
radio gear and centering the servos, I mounted the radio tray in the
hull, routed the dual pushrods for the rudder through the transom,
secured them to the rudder, and checked for free motion.
FINISHING TOUCHES: A full decal set is supplied
to finish the hull. The large graphics require care to apply properly,
but the extra time pays off with a sharp-looking boat. A bit of paint is
required to detail the cockpit area; this can be as simple as a coat of
black around the molded pilot figures or as complex as your imagination
wishes. Two-piece helmets with molded-in driver faces are included, but
I replaced these with some visored helmets I had in my R/C car "spares"
box. Why the substitution? I didn't feel like painting those faces—and
with a sunny afternoon urging me to finish the boat and hit the water,
could you blame me? I screwed the heads into place, attached the
cockpit/hatch with a body clip, and packed up for a trip to the pond.
Overall, the Triton has good performance, and it's not too challenging
to build. If you want to command the seas, what better vehicle to use
than a Triton.
ON THE WATER REPORT:
I expected the Triton to provide decent first-timer speed but fall
short of the "now-we're-having-fun" velocity more experienced
boaters are used to. Although it does have two motors, I expected
only so much from the little silver-can stockers. I was pleasantly
surprised when the Triton shot off with a surprising punch and
impressive spray from the transom. The boat got on plane almost
immediately and sped across the calm pond with its bow held in a
perfect off-shore racer attitude—looks like Academy got that CG just
right. Jaded speed-junkie types will ask for more speed, but the
Triton's target customer (the first-time boater) should find nothing
lacking in performance. The boat proved to be very stable when
turning aggressively, and run times were decent—about 10 minutes
with the Trinity* Amp-Max II packs I chose. Be warned, however, that
the enclosed motors get very hot; let 'em cool between runs!
