Technical Performance

The HOBAO HYPER TT2.0 chassis represents a pinnacle of precision engineering in the 1/10 scale RC truck category. The hard anodised CNC aluminium construction provides exceptional rigidity whilst maintaining a lightweight profile that directly contributes to superior acceleration and handling characteristics. At just 3mm thick, the aluminium plate has been engineered through FEA analysis to maximise strength-to-weight ratio, removing material only where loads are minimal whilst reinforcing critical stress points. The drivetrain utilises a central Ø4mm hardened steel driveshaft with a 10T pinion gear and 39T ring gear (MOD 1) configuration, paired with a 40T MOD 1 centre spur gear for optimised power delivery across the rev range. The full differential system—front, centre and rear with metal bevel gears and anti-leakage housing—distributes power efficiently whilst maintaining the precision tolerances necessary for competitive racing. Suspension mounting uses 3mm CNC aluminium shock towers with adjustable geometry, accommodating the integrated front and rear anti-roll bars that provide essential chassis stiffness during aggressive cornering. The vehicle's drivetrain components use CVA axles at the front (Ø3.2mm hardened steel) and dogbone axles at the rear (Ø3.2mm hardened steel), combinations proven in competitive racing to provide reliability and performance. Shock absorbers feature aluminium 12mm big bodies with 3.5mm shafts, aluminium adjustable rings and protective shock caps, filled with #600 silicone oil for consistent damping response. Standard spring rates are 0.86kg/cm for the front (50mm length, blue) and 0.64kg/cm for the rear (65mm length, blue), with optional alternative rates available for different track conditions. The motor mount is a laydown design constructed from CNC aluminium, compatible with motors measuring below 38mm, paired with a 13T MOD 1 motor gear and 40T MOD 1 spur gear for optimal power and acceleration characteristics. For those requiring optional upgrades, carbon fibre inserts, alternative spring rates, alternative wheel hex hubs and an optional aluminium driveshaft are available to fine-tune performance further. This chassis is designed to work with 2-channel radio systems, high-torque steering servos, dedicated ESCs and standard LiPo batteries, making it compatible with most modern RC equipment currently used in the UK RC community.
