Fully Tunable chassis and suspension The Sprint 2 Flux is the ideal club racer and is a great entry into RC racing fun! Its chassis is almost indestructible and easy to drive, the electronics and drivetrain are virtually maintenance- and worry-free, and it also has all the race tuning features you need for a good set up on almost every racetrack. A belt driven 4WD system guarantees smooth power transfer and high grip on a wide variety of paved surfaces. Plus, the race-proven suspension with oil filled shock absorbers offers racing features you wouldn't expect from a club-level touring car.
The stock settings right out of the box will give you great handling on almost every surface, and with the fully adjustable suspension you'll have control over all important settings including camber, toe-, ride height, Ackerman, springs and more – enough settings to fine-tune your car for low lap times! 8 rubber sealed ball bearings at the wheel axles and 6 more ball bearings at all other axles don't wear out like metal or plastic bushings and provide lower friction and more speed.

HPI Quality Electronics


The reliable and sturdy HPI TF-1 radio controls the RTR Sprint 2 Flux, giving you ultimate control in a comfortably designed radio! The steering wheel design makes you feel as if you're actually driving the car, and the trigger-style throttle and brake controls provide you with finger-sensitive action when accelerating and stopping! The radio transmitter features interchangeable frequency crystals, servo reverse switches, a retractable aerial with sliding cover, easy access to radio adjustments and simple battery replacement. Choose Your Own Battery and Charger The Sprint 2 Flux features all the electronics necessary to get running, except the car battery, charger and 8 AA batteries. This allows you to choose the right battery for your purposes: get a handful of cheap Ni-MH packs for car park bashing, or arm yourself with high-voltage Li-Po racing packs for top-speed lap attacks and insane top speed! The Flux Motiv speedo features a real Dean's low-loss, high power battery plug, so make sure your batteries include a female Dean's plug for simplicity and reliability. You can also gear yourself up with a simple peak charger or a computerized fast charger, it's your choice! Ask at your hobby shop dealer for the best battery and charger for your needs. Standard Electronics Because all of the electronics are standard-size RC components with standardized connectors, any or all of the components can be upgraded at any time, or moved into a different RC vehicle in the future. The RTR Sprint 2 Flux will take any stick-type NiMH 6-cell or 2S LiPo battery pack fitted with a standard Deans-type plug, such as the HPI Plazma battery packs #101933, #101940, #101941 and #101942.
