Highlights

Automatic Self Righting Hull Design

The Rapid features a self-righting hull design that automatically flips the boat back to an upright position if it capsizes. This smart feature ensures uninterrupted fun and minimises downtime, allowing you to quickly resume your on-water sessions without manual retrieval.

Integrated Stability And Steering Control

Integrated Stability And Steering Control

The waterproof receiver and ESC unit includes intelligent stability algorithms. It senses the boat's direction and makes automatic steering corrections to maintain straight-line acceleration and sharper cornering. This system works in the background to improve control without limiting your throttle input.

Reinforced ABS Hull With Double Seal

Reinforced ABS Hull With Double Seal

The clean hull design is built in layers for maximum rigidity at the transom and ride pad. Constructed from robust ABS, it withstands the stress of high-speed runs. A double boat cover design provides enhanced waterproofing to keep internal electronics dry.

2.4GHz Radio System With Safety Alarms

2.4GHz Radio System With Safety Alarms

Race multiple boats without interference using the UA13 2.4GHz radio system. It features essential low battery and out-of-range alarms, giving you real-time feedback on your sailing status. These alerts help you avoid signal loss and ensure a safe return to shore.

Motor Water Cooling And Waterproof Servo

Motor Water Cooling And Waterproof Servo

    I bought this as a Christmas present for my 11-year-old nephew. He absolutely loves it! It goes pretty fast, is easy for beginners to handle and we were getting about 15 minutes of use from a single charge. I deducted a star because of questionable build quality - after just two days, the wheel on the controller no longer returns to centre automatically when it's turned to the right (but it does when turned to the left). This will need to be repaired/replaced under warranty, which is a nuisance.

    Seriously excellent service. I was on the waiting list for the udi RC rapid boat to come in. It took less than 1 week and I was able to collect even on their day off. My 11 year old loves the boat. Easy to use and doesn’t capsize on the river. Would recommend.
