The HPI E-Firestorm is the first electric 2WD truck
to be released by HPI Racing, and is the product of years of
research and the collected knowledge that has made HPI nitro trucks so
successful! Ready to go right out of the box, the E-Firestorm is
factory pre-assembled and pre-painted, built from tough nitro truck parts and
designed using the latest computer software and engineering
know-how.
The E-Firestorm fills the gap that once existed in
the HPI kit line-up, becoming the first-ever HPI electric 2WD truck!
Being the first in a new line of groundbreaking RC kits is never
easy, however HPI designers have taken inspiration from the amazing
Firestorm 10T nitro truck as well as
top-level racing trucks.
The unique chassis of the
E-Firestorm is all-new and totally new to the HPI line-up of kits.
It is made from a moulded composite plastic
for high rigidity, and is modularly designed so the front and rear
suspension parts can be removed or added when maintenance is
required.
To enhance the durability of the chassis, the interior
is braced longitudinally and the front and rear ends feature extra
bracing to help keep the suspension doing its job. The deeply
upturned sides of the chassis allow the ride height to
be set very low for an off-road truck, but
prevent the sides of the chassis from digging
in at extreme suspension angles.
Motor Mount
The rear-mounted motor provides the best
balance for the rear suspension, allowing the motor to offset the
weight of the battery and giving the rear tyres extra weight for
maximum traction on any type of surface. The placement of the motor
also allows new types of brushless motors easily fit in the chassis,
giving you the best opportunity for insane top speeds!
Battery Holder
Featuring prominently in the chassis is the
battery which provides all the power to the motor and steering servo. A large battery
compartment allows the fitting of any standard stick pack or
side-by-side pack design, even the larger 7-cell packs which provide
more voltage and power for huge top speeds! In addition to fitting
the industry standard nickel-metal
hydride (Ni-MH) battery packs, lithium polymer (LiPo) and other
newer battery designs are able to easily fit in the chassis, giving
the E-Firestorm a unique ‘future-proof’ design.
Because it is
the heaviest single component of the E-Firestorm, special
consideration was given to the placement of the battery in the
chassis. The battery can be fitted all the way forward to enhance
steering on low-speed race tracks, or fitted all the way to the rear
to give greater traction on larger high-speed
tracks.
The E-Firestorm uses the tough suspension design
and suspension geometry from the Firestorm 10T truck for extreme
ruggedness and durability. Extra-long suspension arms are damped by
adjustable shock absorbers, and turnbuckle camber links can be
mounted in multiple locations for fine-tuning of the handling. This
makes the E-Firestorm nimble and easy to handle in all
conditions!
The E-Firestorm uses the same front suspension as
the nitro Firestorm, so you know it will be tough and long-lasting.
The entire front end of the nitro Firestorm can actually be removed
and bolted right on the E-Firestorm! This means that not only will
spares be easy to find, but the tough front end parts of the
Firestorm are the standard parts of the E-Firestorm. The rear end of
both trucks share several parts as well, including the hubs, shocks
and turnbuckles.
Hubs and
Steering Knuckles
The front hubs and steering
knuckles, plus the rear uprights, are moulded from tough nylon to
take any sort of punishment you can dish out. The optional camber
link locations on the hubs and uprights also give you extra tuning
opportunities at the track.
The front hubs feature alloy
steel axles that spin on high-quality rubber sealed ball bearings
for optimum efficiency. The alloy steel is extremely strong to take
the abuse of rough landings and the occasional crash. The way the
axle is mounted in the steering knuckle allows the best steering
action possible, giving you maximum steering input and direct
feedback through the tight and twisty sections of the
racetrack!
Adjustable
Turnbuckles
Steel turnbuckle camber links allow
you to make tuning adjustments while the links are on the truck, so
tuning is quick and very easy to do. You also have the option of
different mounting points for the turnbuckles as well, with two
inner and two outer mounting positions for each camber link, giving
you the ability to change the suspension geometry to suit track
conditions and your own unique driving style.
The steering
links also use adjustable steel turnbuckles, allowing you to quickly
change the front toe setting for lighter or more aggressive
steering. Optional Ackerman holes on the steering arms give you
further adjustment and the ability to further alter the steering
action.
High-Grip
Tyres
To get maximum performance on and off the
track, the E-Firestorm uses the same tyres as the groundbreaking
Firestorm 10T: Front Line asymmetric ribbed front tyres and Ground
Assault medium pin rear tyres. This combination of precise control
and massive traction gives you ultimate control and speed!
Front: Front Line asymmetric ribbed
Rear: Ground Assault medium pin
Gear
Box
A tough plastic 87-tooth spur gear is driven
by the motor’s 19-tooth pinion gear, providing a great balance
between initial acceleration and top speed. Protecting the spur gear
and transmission is an adjustable dual-pad slipper clutch, a feature
normally seen on race-prepared racing trucks and
buggies!
A tough nylon spur gear cover protects the gears
from rocks and dirt, and features a removable rubber plug for
adjusting the slipper clutch with a standard size hex wrench, which
is supplied. The motor and spur gear cover mount onto a black
aluminium plate for increased cooling and secure
support.
Getting the power to the rear wheels is a durable
low-profile gear transmission that features all-metal gears for
extra toughness! The gearbox uses a 2.6 to 1 gear ratio to enhance
traction and efficiency in all conditions. Directly driving the
driveshafts is a sealed planetary gear differential, giving you
exemplary corner grip as well as longevity and minimal maintenance.
The low profile transmission enhances the E-Firestorm’s centre of
gravity, keeping the handling tight and tidy! Tight like a
tiger!
15-Turns Motor
Giving the E-Firestorm the ability to get
over and around anything is 15-turn motor, the HPI Fireball! This
fixed-endbell motor has the grunt and power to give the E-Firestorm
plenty of acceleration and high top speeds! With standard ‘bullet’
connectors, the Fireball can work with any electronic speed
controller or can be replaced by a faster motor to give you even
more speed and torque.。
Finishing off the E-Firestorm is an all-new DSX-2
sleek racing body! Pre-painted in flashy racing colours, it will
definitely look the part at any race track! It is pre-cut and
pre-drilled so there is absolutely no preparation time required,
just fit it on and go!
