Maverick QuantumR and QuantumRX: 1/8 4S brushless road and rally cars
The QuantumR is the Maverick Quantum family on the road: a 1/8 scale 4WD chassis with an HPI Flux 2250KV brushless motor and 120A waterproof ESC that run on anything from a 2S to a 4S LiPo. Every model has an HD steel drivetrain, metal 4-gear differentials front and rear with a centre differential, oil-filled adjustable aluminium coilover shocks and the MTX-244 steering-wheel transmitter. The QuantumR Muscle Car and QuantumR Race Truck are low-slung on-road cars on belted Tredz Vortex tyres; the QuantumRX Rally Car raises the same chassis onto long-travel shocks and Tredz Stage gravel tyres for dirt and gravel, and the QuantumRX Rally Conversion Set turns an existing QuantumR into one. All are ready to run; the LiPo battery and charger are not included.

Which QuantumR should I choose?
Start with the surface. For tarmac, car parks and smooth ground, the QuantumR Muscle Car or Race Truck (£224.99) share the same chassis, wheels and tyres, so pick on looks: the muscle car or the pick-up. For gravel, dirt and rough ground, the QuantumRX Rally Car (£314.98) adds long-travel shocks, gravel tyres, rally wheels and extra protection for the chassis and centre differential. If you already own a QuantumR, the Rally Conversion Set (£89.99) brings it up to QuantumRX specification; a QuantumR plus the set costs the same as the QuantumRX, so it is a way to have both set-ups. All four run on 4S power, so a 2S or 3S LiPo is the gentler way in for newer drivers.
Spares are in Maverick spare parts. For the 1/10 off-road trucks the QuantumR grew out of, see the Maverick Quantum2 range.
