Ordered flishrc cobra. Communication was great. Ordered larger batteries but they were the wrong size. Olly shipped the right batteries and gave a refund for the difference I paid. Couldn't ask for more. Thanks for the help with the order.

The seller knew I was after one and very kindly informed me when they came back into stock so now have a Flywing Bell 206. Fantastic bit of kit. Well worth the wait.

About this product
The Maverick QuantumRX Flux 4S Rally Car is the off-road member of the QuantumR family: a 1/8 scale 4WD brushless rally car with long-travel shocks, Tredz Stage belted gravel tyres and rally wheels on the Quantum+ chassis. The same HPI Flux 2250KV motor and 120A waterproof ESC as the on-road QuantumR run on anything from a 2S to a 4S LiPo, so it keeps the speed but adds grip on gravel, dirt and loose surfaces. It is 550mm long on a 322mm wheelbase and arrives ready to run with a steering-wheel transmitter. The LiPo battery and charger are not included.
Who it’s for
Drivers who want 4S brushless pace away from the tarmac – gravel car parks, dirt tracks and makeshift rally stages – with the protection to keep going when the surface gets rough. It is quick enough on 4S to reward some RC experience. Compare it with the on-road Muscle Car and Race Truck in the Maverick QuantumR and QuantumRX range, and choose your colour from the options above.
Key features
- 4S Flux brushless power – 2250KV motor and 120A waterproof ESC, 2S to 4S LiPo capable (14.8V on 4S)
- Rally running gear – long-travel oil-filled adjustable aluminium coilover shocks, independent suspension and Tredz Stage belted gravel tyres on rally wheels
- Quantum+ chassis protected for off-road – raised front bumper, foam front bumper, rear diffuser and a spur gear cover to keep debris out
- HD steel drivetrain – front universals, rear driveshafts and axles, centre driveshafts, diff cups and turnbuckles in high-strength steel
- Metal 4-gear differentials front and rear plus a centre differential for smooth power delivery and better drivability
- Rally body – pre-cut, factory-finished polycarbonate shell with a dual-level rear wing, side mirrors and rear diffuser
- MTX-244 2.4GHz steering-wheel transmitter included, with a moulded tub chassis with hex-pattern reinforcement underneath
Frequently Asked Questions
All three share the 1/8 Quantum+ chassis and 4S Flux brushless system. The QuantumR Muscle Car and Race Truck are low-slung on-road cars; the QuantumRX adds long-travel shocks, gravel tyres, rally wheels and extra protection for off-road driving.
No. It needs a 2S to 4S LiPo with a T-plug and a LiPo charger, both bought separately. The transmitter takes four AA batteries, also not included.
The steering-wheel transmitter is intuitive, but on 4S it is a fast car. Newer drivers can start on a 2S or 3S LiPo and step up to 4S later.
The conversion set brings a QuantumR up to QuantumRX specification with a rally bodyshell, off-road tyres, raised suspension geometry and centre differential protection. The QuantumRX is that set-up ready to run from the box.
