34 Inch Pro Boat Miss Illinois U-34 Unlimited Hydro 8S, 113kph RC Boat

The Pro Boat® Miss Illinois U-34 34" Brushless Hydro Boat RTR has the look and performance of the world’s fastest Unlimited boats. This brushless RTR is ready to rip across the water right out of the box.

Pro Boat Miss Illinois U-34 34" Unlimited Hydro Race RTR Boat Overview

Experience the heart-pounding rush of H1 Unlimited hydroplane racing with the Pro Boat® Miss Illinois U-34 34" Brushless Hydro Boat RTR. Modeled after the world's fastest race boats, machines that push nearly 200 mph and run on turbine engines producing up to 3,000 horsepower, this precision-built model captures the aggressive stance, signature rooster tail, and raw speed of its full-scale inspiration. Powered by the Spektrum™ 8S 160A Smart ESC and the high-output Spektrum Marine 4685 4-pole water-cooled brushless motor, the U-34 Hydro launches off the line with authority and screams across the surface at 70+ MPH. This RTR delivers a lake-ready platform with premium electronics, CNC aluminum hardware, and enough performance to turn heads at any lake. True hydroplane platforms like this are typically custom-built and cost-prohibitive, so getting one in a ready-to-run package that performs at this level will get you on the water that much faster!

At the heart of the U-34's handling is its on-the-fly adjustable canard system, fully integrated with the included custom-programmed DX3 Smart transmitter. Real-time aerodynamic tuning lets 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. Pair that with a fully adjustable rear wing, a pre-sharpened aluminum turn fin, and an adjustable CNC aluminum propeller strut, and you have a platform that rewards both speed seekers and hands-on tuners.

Durability and convenience come standard. The SSL (Strap, Slide, Lock) battery tray system makes swapping packs effortless, while the breakaway aluminum rudder protects against underwater debris. Stainless steel hardware throughout ensures long-lasting, rust-free performance run after run. The clean molded interior features organized cooling line routes, a waterproof receiver box, and a grease catch to prevent the flinging of grease from the flex shaft keeping maintenance simple and the inside looking sharp.

Whether you're looking for a scale modern hydro for your shelf, a hobbyist looking to push performance limits, or a first-time hydroplane pilot ready to experience exhilarating speed, the U-34 Hydro delivers speed, excitement, and scale realism that mirrors its full-size 1:1 counterpart all straight out of the box.

• Blistering 8S-capable brushless power system
• On-the-fly adjustable canard with emergency full-downforce button
• Convenient, fast, and easy battery tray system that snap into place with a single hand

Dominant 8S Brushless Power

Experience the raw intensity of the Spektrum 8S 160A ESC and oversized SPMXMM1000 Brushless Motor. This massive power system delivers incredible "out of the hole" acceleration and blistering top speeds that rival its 1:1 scale counterpart. Whether you are tearing through straightaways or powering out of a turn, this 34” powerhouse offers a level of performance that redefines the modern RC hydroplane.

On-the-Fly Adjustable Canard

Take command of your boat's flight with the integrated Adjustable Front Canard, a high-performance wing system designed for real-time tuning. This advanced setup allows you to make precision trim adjustments on the fly via the custom-programmed DX3 transmitter, including a dedicated "extra lift" button to break surface tension instantly. Engineered with a full steel spar and rigid aluminum bell crank, every input is immediate and flex-free for surgical precision at high speeds.

Pro Boat SSL Battery System

Pro Boat's innovative Strap, Slide, Lock (SSL) battery system eliminates the struggle of securing battery packs in tight hull spaces. By strapping your batteries to molded trays that slide and lock into place, you can complete battery swaps in seconds and get back on the water faster. This system ensures your center of gravity remains consistent every run, always providing predictable and reliable handling.

Integrated Blow-Over Prevention

High-speed hydroplanes are a constant battle between lift and drag, but the U-34 features a custom-programmed emergency override for ultimate safety. With a single touch, the canard shifts to its most aggressive downward angle to provide maximum downforce and keep the hull glued to the water. This safety margin prevents costly flips and blow-overs in turbulent conditions, giving you the confidence to push the limits of performance.

Precision Injection-Molded Hull

Achieving elite performance requires sharp lines and a perfectly flat ride plate, which is why the U-34 features a high-tolerance injection-molded hull. This design provides the durability and accuracy of a blueprinted race boat straight out of the box without the need for manual sanding or modification. The result is a rock-solid platform that tracks straight and handles the immense torque of an 8S system with ease.

Real-Time Smart Telemetry

Stay informed throughout your entire run with Spektrum Smart technology that sends vital battery data directly to the included DX3 transmitter. For those seeking deeper insights, binding the U-34 to any Spektrum programmable radio unlocks advanced tracking of amp draw, motor RPM, Battery and ESC Temperatures, and precise voltage. This real-time feedback allows you to monitor your electronics' status and manage your run time with surgical precision.

Lake-Ready CNC & Stainless Hardware

The U-34 is built for longevity and precise tuning with a full suite of CNC-machined aluminum and rust-free stainless-steel hardware. These durable components let you dial in the drive system and rear wing angles to match changing water conditions. From the aluminum two-blade propeller and adjustable propeller strut to the break-away aluminum rudder and pre-sharpened adjustable turn fin, every piece of running hardware is engineered to keep you on-the-water and off the workbench.

Ready-to-Run

Everything comes fully assembled so users can go from unboxing to driving in minutes. Eliminates the time and complexity of building while delivering reliable performance from the very first run.

Adjustable Rear Wing

Fine-tune aerodynamic balance with the fully adjustable rear wing. Add downforce for stability or reduce drag to help lift the rear of the hull and increase speed.

Adjustable Turn Fin

Fine-tune your handling using the pre-sharpened aluminum turn fin. By adjusting its depth and angle, you can help counteract prop torque, which naturally pulls the boat to the right, for a more neutral feel during straight-line runs. For dedicated oval racing, the Optional Hooked Turn Fin can be installed to maximize side-force and prevent the sponson from skipping during high-speed, right-hand turns.

Waterproof Receiver Box

A sealed enclosure protects the receiver from water intrusion, preventing signal loss, corrosion, or electrical damage during operation. The box is securely mounted to the hull using stainless steel hardware and features an integrated rubber grommet for a watertight wire exit. This bolt-down design ensures a pressurized seal, keeping your sensitive electronics completely dry even in the event of a flip or water intrusion inside the hull.

Dual Independent Water-Cooling System

Separate cooling lines for the motor and ESC prevent heat buildup, maintaining optimal temperatures during extended high-speed runs. The integrated dual water pickups are built directly into the rudder, providing a clean setup that reduces the overall drag caused by external pickups. This streamlined design ensures maximum water flow for cooling without sacrificing the boat's top-end speed or handling.

Molded Cooling Line Routing

Integrated channels help keep cooling lines organized and secure, maintaining a clean and efficient interior layout. By preventing kinks or loose hoses from interfering with moving parts, these channels ensure consistent water flow and cooling performance. This streamlined routing also makes it easier to inspect your connections and perform routine maintenance between runs.

Stuffing Tube Grease Catch

The stuffing tube grease catch helps prevent excess grease from the flex shaft from spreading throughout the interior of the hull. By containing the inevitable spray from high-speed rotation, this catch keeps your electronics and cooling lines free from oily buildup. A cleaner bilge also makes it much easier to wipe down the boat and perform routine maintenance after a day at the lake.

Custom Hand-Painted Finish

Hand-painted detailing adds realism and premium presentation, giving the boat the appearance of a true scale performance machine rather than a simple molded shell.
