The tyre-and-bearing combination ensures reliable performance on rock, dirt, grass and pavement.
• 0.5kg Digital Steering Servo with Upgrade Compatibility — The steering system uses a 0.5kg torque digital servo (5g) that provides precise, responsive control. The system is upgradeable to front and rear steering for enhanced customisation, and a separate 0.5kg gear-shift servo manages transmission changes.
• Compact, Trail-Ready Proportions — At 191mm long, 122mm wide and 100mm tall, with a 135mm wheelbase and 27mm ground clearance, the UCX24 is small enough for indoor play yet realistic in scale and proportion. The 102mm front and rear track width provides a balanced, stable stance.
• Approx. 50m Transmission Distance — The 2.4GHz radio system delivers a transmission distance of approximately 50 metres, giving you plenty of range for outdoor trail running and technical crawling sessions without signal loss.

Technical Performance

The UDI UCX24 Snow Leopard represents a significant step forward in compact RC crawler engineering. At its heart sits a 1212-01-1/L60DZ brushless outrunner motor (29.5mm overall length, 22.5mm can length, 15.8mm diameter, 2mm output shaft) that weighs just 15.4g yet delivers impressive torque and efficiency across the rev range. The integrated ESC (measuring L33.4 × W30 × H12.3mm, weighing approximately 10.8g) features advanced electronics including Low Voltage Detection (LVD) to protect your battery, Weak Signal Detection (WSD) for radio reliability, and a stable 5V/1A BEC to power the servo and receiver. The ESC is not waterproof, so care should be taken when operating in wet conditions. The brushless system requires a 2S LiPo battery (7.4V nominal, such as the 350mAh supplied unit), which is included with every vehicle. The shiftable centre transmission features mechanical shifting with three speeds: low gear (1:58.6 ratio for crawling), neutral, and high gear (1:9.3 ratio for faster running). The complete vehicle weighs just 352g including the battery, yet the all-metal drivetrain and reinforced frame ensure reliability under sustained load. The symmetrical chassis layout provides balanced weight distribution and predictable handling characteristics. Front and rear universal drive shafts transfer power reliably, whilst the independent suspension damping system absorbs impacts and maintains traction. The high-speed sealed ball bearings throughout reduce friction and extend component life. Ground clearance of 27mm allows the UCX24 to clear obstacles and technical features that would stop conventional micro RC cars. With proper maintenance and care, the brushless motor, metal transmission and sealed bearings mean the UCX24 will deliver years of reliable service. The integrated ESC and compact motor packaging make the vehicle maintenance-friendly, with straightforward battery charging via the included USB charger and simple servo access for adjustments.
