At the heart of the GLEAM PRO is a high-output 2845-4700KV brushless motor paired with a programmable 60A brushless ESC, providing explosive acceleration and support for both 2S and 3S LiPo batteries. With motor speeds reaching up to 60,000 RPM, the UD1204PRO is built to deliver thrilling speed and rapid response on dirt, gravel, tarmac and off-road terrain.
To handle the increased power, UDIRC has equipped the PRO version with a strengthened steel drivetrain featuring upgraded 40Cr chromoly steel transmission gears, steel universal joint driveshafts and a metal centre driveline. This heavy-duty transmission system is designed to maximise reliability under high loads while ensuring efficient power delivery to all four wheels.
A fully enclosed transmission housing protects the drivetrain from dirt, dust, stones, and debris, helping maintain smooth operation and reducing wear during demanding off-road use. The sealed design also helps retain lubrication, lower friction and extend the lifespan of gears, bearings and drivetrain components.
Maintenance has been made remarkably simple thanks to the innovative quick-release drivetrain design. The complete centre drivetrain can be removed in seconds, while the front and rear differentials feature a rapid-access design that allows servicing or differential changes in under 30 seconds. This race-inspired modular layout dramatically reduces maintenance time and keeps drivers focused on running rather than wrenching.
Handling is equally impressive, with adjustable aluminium oil-filled hydraulic shock absorbers and a dual ball steering system that increases steering angle and precision. Combined with durable suspension components, adjustable spring preload and a wide-track chassis layout, the UD1204PRO provides excellent stability, predictable cornering behaviour and confidence-inspiring control at high speed.
