FMS Model 1:7 Ford Bronco U4 Funhaver 24 FMS-RCC-2237 4WD Brushless RC Truck
The FMS Model 1:7 Ford Bronco U4 Funhaver is an officially licensed, large-scale 4WD brushless Ultra4 desert racing truck developed in collaboration with Ford and Vaughn Gittin Jr.’s Fun-Haver Off-Road team. Engineered for high-speed desert bashing, dune jumping, and technical rock crawling, it blends extreme 6S brushless power with scale off-road authenticity.
This giant-scale racer resolves common issues like chassis flex under high speeds, roll-over instability, and drive-dampening power loss by incorporating an 8S-rated aluminum chassis plate, long-travel aluminum oil-filled shocks, and heavy-duty steel drivetrain components. Powered by a high-output 4282 2000KV brushless motor, a 150A 6S waterproof ESC, and a 35kg high-torque metal-gear steering servo, it reaches speeds over 50+ mph (80+ km/h). Compatible with 4S–6S LiPo batteries and 2.4GHz transmitter systems, its main benefit is delivering true Ultra4 King of the Hammers performance in a scale Ford Bronco package straight out of the box.
Product Details
The FMS Model 1:7 Ford Bronco U4 Funhaver is a high-performance 1/7 scale 4WD desert racer engineered for extreme RC enthusiasts and off-road racing fans who require blistering top speeds alongside scale rock-crawling capabilities. It is commonly used for high-speed sand dune bashing, gravel drifting, and Ultra4-style rock trails where smaller 1/10 scale trucks lack the ground clearance and stability to handle harsh impacts. Compatible with dual 2S/3S or single 4S/6S LiPo battery setups and 2.4GHz radio gear, it allows drivers to experience scale suspension compression and responsive steering under heavy throttle.
