Micro RC Crawler with Brushless Performance
The Furitek Titan U4 Ultimate 24 ARTR 1/24 4WD Brushless Rock Crawler is a professionally built micro crawler combining a full titanium U4-style chassis with a sensored brushless drivetrain and detailed scale cockpit. The Tri-Unity Pro sensored field-oriented control (FOC) drive system integrates the motor, electronic speed control (ESC), and transmission for smooth startup, precise low-speed throttle control, and predictable power delivery. A Furitek Raptor high-speed steering servo provides strong front steering authority, while the wider stance, low-mounted battery, brass steering knuckles, and high-clearance suspension components are designed around technical crawling. The included Gripor V2 four-channel transmitter and receiver system completes the radio setup, with support for 2-3S LiPo batteries.
About the Titan U4 Ultimate 24
Full Titanium U4-Style Chassis
The Titan U4 Ultimate 24 is built around a full titanium tube cage and chassis structure with titanium body panels and an open U4-inspired design. The exposed suspension and drivetrain layout gives the crawler the appearance of a compact Ultra4-style race machine, while the open cage keeps the detailed cockpit visible. A CNC-machined rear scale storage box adds another mechanical detail to the rear of the chassis, complementing the titanium construction and equipment-inspired U4 styling.
Brushless Power & FOC
The Tri-Unity Pro sensored FOC drive system replaces a conventional separate motor, ESC, and transmission arrangement with an integrated system designed for smooth and controlled power delivery. Sensored brushless technology and FOC motor control provide strong low-speed torque and precise throttle response when working through technical terrain. Steering is handled by the 11kg high-speed servo with an aluminum servo horn, while the front axle provides approximately 50° of steering angle for tight turning and line corrections. The +5-millimeter extended aluminum axles, brass steering knuckles, and wider U4-inspired stance further contribute to the crawler's stability and front-end traction.
Technical Crawling & Scale Cockpit Detail
The chassis incorporates a 10° angled aluminum skid plate and high-clearance suspension links to help the crawler clear rocks, ledges, and other obstacles without hanging up underneath. Aluminum oil-filled shocks provide controlled compression and rebound, while steel driveshafts handle power transfer between the integrated drivetrain and axles. A low side-mounted battery position helps lower the center of gravity and reduce chassis roll during climbs and side-hills. Above the suspension, the detailed dual-seat cockpit includes a scale driver, Micro Tesla DigiBoard with OLED display, and a servo-operated scale steering wheel that turns with the front wheels for a more dynamic U4 driving experience.
