Technical Performance
At the heart of this 1/7 scale brushless RC truck lies the Spektrum Firma system, representing genuine Smart electronics that deliver professional-grade performance monitoring and control. The Firma 4074 motor rated at 2050KV produces smooth, consistent power through its 4-pole construction, whilst the 150A Firma ESC handles the 6S LiPo capability (also compatible with 4S) with sophisticated current limiting, low-voltage cut-off protection, thermal overload safety and user-programmable settings for punch, brake strength, BEC output, reverse speed and motor timing.
The drivetrain is engineered for durability with a final drive ratio of 8.58:1 and an internal gear ratio of 2.8:1, translating to genuine 80+ MPH capability in optimum conditions with the included speed pinion gear (15T). The chassis measures 695mm in length, 310mm in width and 200mm in height, weighing just 5kg when fully assembled. Front and rear tracks measure 308mm and 305mm respectively, with a 406mm wheelbase that balances stability and manoeuvrability. Ground clearance stands at 15mm, providing adequate elevation for street bash environments.
Build quality throughout is exceptional, with rubber-shielded full-set ball bearings, captured ball ends that cannot pop off, hub nut O-rings for security, and Safe-D input gears keyed to drive cups with composite sleeves to fortify drive cup set screw retention. The 6061-T6 anodised aluminium construction resists corrosion, whilst adjustable body mounts allow fine-tuning of aerodynamic feel. This is a genuine all-road capable truck that performs equally well on tarmac and dirt, making it incredibly versatile for UK RC enthusiasts with access to varied bashing locations.
