Designer Erik Shauver put all his design experience from designing HPI's high performance cars, like the Hellfire and the Pro 4, into the Firestorm. It combines the latest advances in RC racing truck technology and suspension design to set a new benchmark in 2WD stadium trucks.In the HPI line up the Firestorm replaces the hugely popular HPI Nitro Rush with a big performance increase at about the same price.It's easy to spot the Firestorm's design heritage from the Hellfire in the sleek black look, the subdued chassis anodizing, and the smart and efficient layout. Many design features of the high spec Hellfire have been carried over - from the black upper deck, the complete set of hex screws, the captured hinge pins front and rear, and the next-level suspension design and layout!Race-inspired features give great handling on all surfaces from open fields, parks, even to your local racing track. The dual-deck design features a 3mm aluminum main chassis and an aluminum upper deck. A low-profile 75cc fuel tank and lay down steering servo help provide a very low center of gravity (CG). A full set of turnbuckles allows you to adjust camber and front toe. The rear toe and anti-squat angles are adjustable using pivot blocks, just like on the high-spec racing buggies. Real oil-filled shocks absorb all bumps and jumps and keep the tires on the ground. Real silicone shock oil is used to provide consistent performance in all temperatures. The shocks even feature threaded shock bodies for easy spring adjustments, and the many shock mounts (3 upper, 2 lower) give a multitude of tuning possibilities. 16 ball bearings provide maximum drive train efficiency for faster top speed and durability. Wide-track suspension and all-new tires front and rear give the Firestorm superb control. Providing extra grip and control are the new square-pin Ground Assault rear tires get the power to the ground and asymmetric dual-edge Front Line tires to keep the Firestorm pointed in the right direction.The Firestorm is as durable as it is nimble, giving you maximum enjoyment under any conditions! The aluminum main chassis and upper deck combine with the steel chassis brace to make the Firestorm extremely stiff. A dual-pad slipper clutch protects the drivetrain from rough landings, while the 0.8 module clutch bell and spur gear are designed for maximum efficiency and reliability. The transmission features a 4.11 to 1 ratio and a sealed planetary gear differential, allowing you to tune the performance of the truck with different diff oils. Stopping the Firestorm is a fiber disk brake actuated by easy to adjust linkage. The steel center chassis brace provides extra stiffness and keeps the gear mesh between the spur and clutch bell consistent. Steel alloy front axles and rear dogbones take the extreme punishment of bashing and racing in the worst possible environments. Protecting the electronics are sealed compartments for the battery pack and receiver, protecting them from the elements and strategically placed for optimum weight balance.The little details weren't missed out either. You can see the designer's perfection in every Firestorm feature such as: a two-stage foam air filter with a 90-degree rubber elbow, fuel tube clips to keep the tubing out of the way of rotating parts, an innovative battery wire routing system, adjustable body posts to fit a variety of optional bodyshells, piston brake caliper actuation, high-flow manifold and silicone tuned pipe coupling and rubber mounts for the fuel tank. All this shows how much HPI listened to devoted owners and fans of stadium nitro RC trucks!On the power front the Firestorm features the new HPI Nitro Star G3.0 engine. This new high output engine features a racing standard SG shaft for better power transfer to the transmission. An aluminum crankcase with cooling fins and large heat sink head provide optimal cooling for long engine life and consistent performance. An aluminum tuned pipe and one-piece manifold give maximum torque and raw stump-pulling power!A reliable, easy pull starter and a dual stage foam filter round out the engine package to make it the ultimate power source.From 'bashers' to racers - the Firestorm has plenty for everyone. The pre-assembled chassis and painted & trimmed body are ideal for the nitro newcomer, while the pure racing technology imbued in the truck make it clear that it can take anything you can throw at it! Racing enthusiasts will marvel at all the features included with the Firestorm, while new RC hobbyists will simply enjoy the benefits of HPI's years of experience in making high quality RC products!The Firestorm is pre-assembled right out of the box - from the factory-fitted radio gear and G3.0 engine to the painted and trimmed desert truck racer bodyshell! The reliable HPI TF-1 AM radio system provides all the control you'll need. Required PartsAA Batteries: 12, 8 for transmitter, 4 for battery box Glow Starter Misc. Items: Building and track equipment Fuel: 2-cycle glow fuel with 20%-25% nitromethane, 16% lubricant- Most of the fuels we carry meet or exceed the lubricant content required for optimum performance and maximum engine life. In the past, the conventional lubricant content used in fuel was 18%. But with new advanced technologies, fuels like Red Alert and O'Donnell for example, have a better quality of lubricants even though the percentages of lubricant content are lower. These high-tech lubricants provide exceptional cooling and protection.
