Technical Performance

The Team Associated RC10 '91 Stealth is engineered as a full race-tuned platform with cutting-edge suspension technology that was genuinely revolutionary in 1991. The combination of long-arm independent suspension with hard-anodised coil-over shocks creates a suspension system that smooths out track imperfections whilst maintaining exceptional grip and stability across demanding surfaces. The low-profile Stealth transmission is protected by an integrated motor and heat sink mounting system, which combines multiple functions into a space-efficient package that reduces weight and improves reliability. The double-deck aluminium chassis provides structural rigidity whilst the carbon fibre top plate keeps weight to a minimum, optimising the centre of gravity for responsive handling. All major moving parts utilise ball bearings to reduce friction and improve efficiency, whilst the precision-machined components throughout the chassis maintain exact geometric relationships under racing stress. The A-Arm and ball joint design permits adjustment of static camber, camber rise, caster, ride height and spring rate, giving experienced builders and setup technicians complete control over suspension tuning to match track conditions. This is a 1/10 scale electric off-road buggy that requires a separate brushless motor, ESC (Electronic Speed Controller) and LiPo battery pack to operate — these are not included in the kit. The RC10 '91 Stealth is designed for clay track racing and will require a quality 2S or 3S LiPo battery depending on gearing and motor selection. Build time will vary depending on builder experience, but expect to invest significant time in assembly, as this is a precision race kit requiring careful attention to detail.
