High-brightness 2-in digital telemetry display

WiFi multi-point hotspot

Built-in GPS

8-hour battery life

Multi-functional Payload Options

With its modular multi-functional payload system and open interface design,
the SplashDrone 4 can quickly adapt to different tasks in the field.

For Filming

For Fishing

Innovative Smooth+ Flight Control

The patented “Smooth+” flight control allows the pilot to finely tune the Roll and Yaw of SplashDrone 4.
Smooth+ makes professional, steady flight control as easy as turning the knobs.
Want to take a steady shot? Simply switch to Smooth+ control, together with our 4K 3-axis gimbal,
you can take high-quality, ultra-smooth & steady shots effortlessly.

3KM Image Transmission

The latest 5.8GHz digital image transmitter and adjustable antennas ensure a clear and reliable
image and control signal range to the SplashDrone 4 of up to 3km while airborne.

Important: Due to the nature of radio waves, when flying just 0.5m above the water,
the range is up to 3km and floating on the water surface the transmission range is 500m


When the drone turns upside down on the water for any reasons, Power-Flip feature
turns the drone back to the normal state to take the control back.

Dynamic Return to pilot

The SplashDrone 4 constantly records the GPS position of the remote controller,
allowing the aircraft to always return to the pilot‘s position even if they are on a moving
boat far away from the original take-off point.

Intelligent Follow Me

Actively track the position of the pilot at a constant angle from the front, side, and back with the camera always pointing to the subject.

Orbit Follow

Automatically follow and orbit around a moving object at a chosen radius. 

Boat Mode

Equipped with floating foams, the boat mode allows SplashDrone 4 to sail on water just like a boat,
providing great underwater shots while remains the water area uninterrupted.
Caves and other overhead environments can now be accessed
by SplashDrone 4 for research, exploration, and underwater photography.

Unrivalled-performance Propulsion System

The more powerful 740Kv Motor, 40A ESC together with optimized aerodynamic design allow for tight, responsive, and total control of SplashDrone 4 in any challenging weather conditions.

Wind Resistance Up To 22 knots

Up To 2kg Payload Capacity

Smart Battery

The new slide-in smart battery has an internal battery management system for real-time power
monitoring and protection both in charging and discharging, ensuring battery health,
safety and longer lifespan. The 6500mAh high-performance lithium technology
cells provide up to 30 minutes of flight time.

Effortless Autopilot

The SwellPro Navifly App

The newly-developed SwellPro Navifly APP enables logging, planning, recording of missions
as well as the control and parameter setting of cameras and other modules in flight.

Cruise Mode

Automatically fly at a designated speed and direction.

Tap To Fly

Autonomously fly to a selected location on the map at a predetermined altitude and speed, and hover awaiting further commands.

Waypoint Mission Planning

Preplan a mission by selecting a series of waypoints on the map with adjustable speed, height, hover time and camera angle at each point. 

Grid Mission Planning

Connect up to 256 waypoints to form a mission area planning and the drone will follow a uniform grid pattern flight path at the selected speed and interval. 

SplashDrone 4 offers API for third-party software to
gather data from sensors and to configure its control of aircraft,
gimbal, camera, and third-party add-ons.

SDK allows deep integration of third-party add-ons to SplashDrone 4.
Together with API, SplashDrone 4 is truly a multi-purpose
& multi-functional platform for your imagination.
