The Bullet MT 3.0 is just one member of a family of HPI rc models - vehicles which are based around a durable
4WD shaft drivetrain, 2 shocks per wheel and double-deck aluminium chassis.
The Bullet off-road trucks feature either Nitro Star 3.0 engines or
silent Flux brushless motor systems, and are available in different
off-road truck varieties. In short, you can get the precise flavour of
off-road performance you want with the HPI Bullet!
The Bullet trucks use a
3mm aluminium plate-style chassis as
the backbone, providing an extremely tough foundation for the
suspension and drivetrain. The aluminium used in the chassis is the very
strong
7075-T6 alloy, which is the best aluminium
available in radio-controlled vehicles and military aircraft, making it
the ideal material for something like the Bullet! For extra stiffness,
the sides of the chassis are upturned and the aluminium radio plate also
acts as an extra stiffening support.
The drivetrain used in all Bullet trucks is a
full-time four-wheel drive shaft-type drivetrain,
just like the one used in 1/8th scale buggies like the World Champion
D8 buggy. A shaft drivetrain is the best option for a kit that's
expected to encounter every possible driving condition and track
surface, so whether you're blasting through mud, water, dirt, grass,
snow or gravel, this is exactly what you what you want!
A strong plastic 54-tooth spur gear takes the power from the engine and
transmits it front and rear through an adjustable dual pad slipper
clutch. A dual pad slipper provides more protection to the drivetrain
than a standard single pad design, and we've included it as standard to
make sure you get the best out of the Bullet.
The centre dogbones drive the front and rear bevel differentials, which
use 4 internal gears for increased durability and lifetime over standard
2-gear diffs. The diff outdrives turn steel outdrives and axles, and
14mm hex adapters spin the cool styled wheels wrapped with unique
all-terrain rubber tyres.
A single
drilled steel disc brake is used for extreme
stopping power. Brake pads shod with material used in full-size trucks
clamp down when the brakes are applied, bringing this beast to a quick
yet controllable stop! All the brake linkage is fully adjustable, but
you can leave it as set from the factory or it can be adjusted for prime
operation on any surface.
For extra efficiency, all the components of the drivetrain, from the spur gear to the wheel axles, spin on rubber-sealed
ball bearings. With these bearings you get long runtimes and long engine life while the rubber seals keep out dust and grime!
The '3.0' in the Bullet MT 3.0 name stands for the powerful
Nitro Star G3.0 engine,
HPI's latest .18-size nitro-breathing powerplant. It's equipped with
the latest modern features taken directly from much more expensive
racing engines, yet it's easy to tune and adjust so hobbyists of all
skill levels can jump right in and have fun! You get the minimum of
hassle with the maximum of wheel-spinning fun!
The Nitro Star G3.0 uses a sophisticated, heat-resistant
composite slide carburettor
for consistent settings at all temperatures and quick response in any
conditions. With 2 adjustment needles, it's simple to tune and simple to
maintain. An accordion style rubber boot protects the internal
mechanism from dust and mud. To protect the engine from power-robbing
dirt, a dual foam air filter is fitted to the carb.
Protecting the engine from excess heat build-up is the large heatsink
head and extra cooling fins on the engine case. Both are made from
aluminium, which dissipates heat quickly and effectively. The black
coating on the case and the dark silver head look great together,
showing the Nitro Star G3.0 has a bit of style to go with all that
power!
