Pro Boat Miss Illinois U-34 34" Brushless Unlimited Hydro Race Boat RTR (8S)

Experience the heart-pounding rush of H1 Unlimited hydroplane racing with the Pro Boat Miss Illinois U-34 — a precision-built 34" scale replica of the world's fastest race boats, machines that push nearly 200 mph and run on turbine engines producing up to 3,000 horsepower. Powered by the Spektrum 8S 160A Smart ESC and the high-output Spektrum Marine 4685 4-pole water-cooled brushless motor, the U-34 launches off the line with explosive acceleration and screams across the surface at 70+ MPH. True unlimited hydroplane platforms are typically custom-built and cost-prohibitive — the U-34 delivers that level of performance in a fully assembled, lake-ready RTR package that goes from unboxing to wide-open throttle in minutes.

At the heart of the U-34's handling advantage is its on-the-fly adjustable canard system, fully integrated with the included custom-programmed Spektrum DX3 Smart 3-channel DSMR transmitter. Real-time aerodynamic trim adjustments via the DX3 let you adapt to changing water and wind conditions mid-run, while a dedicated emergency full-downforce button instantly pins the nose to prevent a blow-over at speed — a critical safety margin when pushing the limits of an 8S hydroplane. Built on a high-tolerance injection-molded composite hull with sharp lines and a perfectly flat ride plate, the U-34 tracks straight and handles the immense torque of 8S power without manual fitting or modification. A fully adjustable rear wing, pre-sharpened aluminum turn fin, and adjustable CNC aluminum propeller strut round out a platform that rewards both speed seekers and hands-on tuners equally.

Pro Boat's SSL (Strap, Slide, Lock) battery tray system makes pack swaps effortless — strap your batteries to the molded trays, slide them into the hull, and lock them into place in seconds for consistent center of gravity and predictable handling every run. A breakaway aluminum rudder protects against underwater debris, dual independent water-cooling lines with integrated rudder pickups keep motor and ESC temps in check during extended high-speed sessions, and a stuffing tube grease catch keeps the interior clean between runs. Stainless steel hardware throughout ensures rust-free longevity, the waterproof receiver box features a bolt-down pressurized seal and rubber grommet wire exit, and Spektrum Smart telemetry delivers real-time battery voltage to the DX3 — with advanced amp draw, motor RPM, temperature, and voltage data available when bound to any Spektrum programmable radio. The hand-painted Miss Illinois U-34 livery in blue and yellow completes a presentation that looks as fast as it runs.
