HPI Firestorm goes BRUSHLESS with new FLUX

RC Car Action - RC Cars & Trucks | HPI Firestorm goes BRUSHLESS with new FLUX

Latest from HPI Racing. BL is positively exploding across the RTR scene, with three rides from Traxxas, Losi’s new Speed-T and now HPI’s entry. We already like the E-Firestorm, but with 5700kV power spinning the knobbies, HPI’s beginner-friendly basher should be closer to a racetrack weapon. 

HPI’s First Brushless Truck!
Coming soon from HPI Racing is the ready-to-run E-Firestorm Flux, HPI’s first-ever brushless motor equipped 2WD 1/10th scale stadium truck. The E-Firestorm Flux takes the durable E-Firestorm platform to the next level with amazing performance from brushless motor technology. The new Flux Brushless system includes a Flux Warp brushless motor that is controlled by Flux Motiv electronic speed control. Add your own battery pack and you’re ready to wheelie and experience the extreme power and efficiency that brushless technology offers.

From the tough ALL METAL gear transmission to full adjustability of the suspension geometry, the E-Firestorm sets a new standard for ready-to-run stadium trucks. Full ball bearings, silicone oil filled threaded shocks – it’s all there, precision built from the factory. Top it off with your choice of a bright red or metallic silver custom screened DSX-2 body and your E-Firestorm Flux is ready to hit the dirt!

Built Tough
TOUGH is the word that best describes the E-Firestorm Flux. Everywhere you look the critical parts have been designed to withstand the rigors of off-road racing. The key to durability for any 2WD stadium truck is the transmission, and the E-Firestorm Flux tranny is extra tough, using all metal gears to easily handle the power of hot electric motors. Inside the tranny is a sealed planetary differential with, again, all metal gears for extra toughness. And everything is protected by an adjustable dual-pad slipper clutch mated to durable 48 pitch gears, with tough steel dogbones and axles transmit the power to the tires.

The Firestorm’s design heritage is easy to spot in the E-Firestorm Flux. The stealthy black color theme is purposefully applied to the sleek curves of the composite nylon main chassis with strategically center-mounted batteries, servo and transmission. The proven tough suspension from the Firestorm is carried over for maximum durability. And subtle features like threaded shock bodies and hex head screws point out that the E-Firestorm Flux is not your average RTR truck, it’s a whole new level of design for the RTR class.

Performance Driven Design
The E-Firestorm Flux uses race-inspired design to give owners full control over suspension adjustments for excellent handling on surfaces like open fields, parks, and even to your local racing track. The lay down steering servo and low profile transmission help provide a very low center of gravity (CG) for quick response. 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 trucks. Silicone oil-filled shocks absorb all bumps and jumps and keep the tires on the ground. The shocks even feature threaded shock bodies for easy spring adjustments, while 3 upper and 2 lower shock mounts give a multitude of tuning possibilities. 14 ball bearings provide maximum drive train efficiency for faster top speed and durability. Wide-track suspension gives the E-Firestorm Flux superb control. Providing extra grip and control are square-pin Ground Assault rear tires, and asymmetric dual-edge Front Line tires keep the E-Firestorm Flux pointed in the right direction.

Brushless Electric Power
The E-Firestorm Flux takes full advantage of all of the benefits of electric power; it’s quiet, clean, powerful, and truly plug-and-play… no starter or fuel needed! Blazing power comes from a Flux Warp brushless motor, controlled by an electronic speed control for complete control over throttle, brakes, and reverse. Add your choice of batteries from NiMh to Li-Po; they all fit easily in the E-Firestorm battery slot that gives secure and tool-free access to the batteries.


Complete Package
From the tough all metal transmission gears to full adjustability of the suspension geometry, the E-Firestorm sets a new standard for ready-to-run stadium trucks. Full ball bearings, brushless 5700kv motor, electronic speed control, silicone oil-filled threaded shocks – it’s all there on the E-Firestorm Flux, precision built from the factory. Top it off with your choice of a bright red or metallic silver custom screened DSX-2 body and your E-Firestorm is ready to hit the dirt!
