Out of stock


The king of the water–Tylosaurus

645mm long hull with high strength aluminum alloy parts, supporting 3S/4S battery. with innovative water cooling system and precise drive control, the modern hull design built in layers for maximum rigidity, and the carbon fiber texture for more technology.

KV1800 Brushless Motor

KV1800 brushless horsepower delivers the muscle you want with the reliability you expect from UDI. The electronic speed control is supports 3S/4S LiPo power. Cooling water is routed through the innovative speed control case and then into a unique sealed motor jacket that allows cooling water to flow directly against the motor for maximum possible heat transfer.

Marine ESC

Innovative waterproof design. Integrated water cooling and heat sink. Built-in low-voltage detection for batteries. Thermal overload protection. Voltage overload protection. Locked rotor protection. Throttle Neutral Setting protection.

Radio System

UA31 radio system arrives with a full complement of tuning features; long-range, high-output, 2.4GHz signal. Also the double protection of Low battery alarm and Out of range alarm, allows you to grasp sailing status of the boat, to avoid lost and get rid of concerns.

Stability Management Receiver with Security

Makes it possible to experience all the extreme power, speed, and acceleration that was engineered into UDIRC models by making it much easier to control the boat in water conditions. Punch it off the line and Receiver goes to work sensing the boat’s direction and making steering corrections to provide straight-ahead full throttle acceleration without loss of control. Also works when turning, first making intuitive corrections to maintain the vehicle’s line, then hammer the throttle earlier in the turn for much faster exit speeds. UDIRC engineers developed superior tuning algorithms that run on high-speed, precision electronic components to create a system that works invisibly, in the background, without ever limiting throttle. Can be fine-tuned for different conditions by simply adjusting the multi-function knob on the transmitter.

Modern Reinforced Hull

The Tylosaurus’s clean, modern hull design is built up in layers for maximum rigidity where it matters most, the transom and ride pad. Lightweight yet incredibly strong, Tylosaurus’s ABS hull is designed to withstand the stress of high-voltage brushless horsepower, without the weight penalty of a fiberglass hull. The transom bulkhead also incorporates bosses for the trim tabs, turn fins, rudder support, and drive strut, eliminating the need for additional hardware inside the hull. In the Mosasaurus’s bow, can be installed with rubber bumpers, adding security as it further stiffens the hull.

Top Speed – 50km

Controllable navigation lightsThe navigation light is more suitable for driving at night to get the boat dynamics, adding more driving fun.

High-Strength Aluminum Hardware
Extreme brushless horsepower demands rigid drive hardware and a flex-free transom for sharp and predicatable handling. The rudder, rudder support, dual trim tabs, turn fins and drive strut are extruded and machined from rugged aluminum alloy for maximum strength. They provide radical turning “bites” and proper hull stance to accommodate the speed of water boiling.

High-Performance Prop

UDI engineers spent many hours testing prop configurations to find the perfect balance of performance, efficiency, and durability. Molded composite construction makes the prop light and tough, with no balancing or sharpening required.

High-Torque Waterproof Servo

Tylosaurus demands a powerful steering servo for responsive performance, and UDIRC delivers with the high-torque servo. Ring seals make the servo completely waterproof.

Battery and Charger

40km/h on 3s LiPo all-out! Contains a AD/DC Adaptor, balance charger and a 2500mAh lipo battery, reducing your worry about purchasing additional accessories and focusing more on the fun of driving.
