The HPI Ken Block WR8 Flux 2015 Ford Fiesta ST RX43 Rally Car is a faithful recreation of Ken Block's "Intergalactic" Ford Fiesta ST RX43 racer. HPI Flux power can propel this replica from a standing start into the 60+ mph (100+km/h) zone with a simple pull of the trigger! Underneath the Ken Block Ford Fiesta ST RX43 body, the WR8 Flux chassis is based on the HPI Bullet RC monster truck, which means it's tough and can take a beating both on and off road. Top it off with semi-slick tarmac tires and replica fifteen52 TurboMac wheels and you've got an instant head-turner!

It's the ideal machine to race your friends on Gymkhana-style courses and multi-surface tracks, or anywhere you like! Like all HPI Racing RTR (Ready-To-Run) cars, the WR8 Flux is completely pre-built: all you have to do is open the box, install the batteries and you are ready for action! 4 AA alkaline HPI Plazma batteries are included for the transmitter, all you need is a 2S or 3S LiPo battery for the car, plus a LiPo charger.

Detailed Replica
There's no getting around it: this is an amazingly detailed replica of Ken Block's Ford Fiesta ST RX43! From the front splitter to the rear wing, and from the roof air intake to the amazing fifteen52 Turbomac wheels, this car looks like the real thing! Every detail of Kenís real car is replicated in 1/8th scale, from the grilles and headlights to the double-level rear wing and spoiler.

Replica fifteen52 Wheels and Real Rubber Tires

For the ultimate in replica looks and fantastic performance, every HPI WR8 with Ken Blockís Ford Fiesta ST RX43 body is fitted with replica fifteen52 TurboMac wheels in a matching wild color scheme. The wheels really help the car stand out as a scale replica, and for extreme performance, the wheels are wrapped with semi-slick HPI tires molded in real rubber. The grippy rubber compound helps the car stick to asphalt or tarmac for real racing action, and the treaded design gives you plenty of grip even on dusty paved surfaces!

The FLUX VEKTOR 4000KV motor delivers massive power - plenty of juice for instant acceleration and enough power to pull out of just about any sideways drift. The brushless design assures maximum performance with nearly no maintenance required.

With the capacity to handle 2S and 3S LiPo power, the FLUX VAPOR Pro electronic speed control is able to handle the latest, most powerful batteries you can fit in the WR8 FLUX. The VAPOR Pro features an integrated cooling fan to keep it cool in warm conditions, reverse so you can back out of jams with ease, and for maximum adjustability it's fully programmable with the optional HPI100573 USB Programming Kit.
