If you are reading this, congrats!! You have bought yourself a SwellPro SplashDrone 3 +, one of the best waterproof drones available in the world, and you will not regret it for one single minute. To get started, we have put together this comprehensive tutorial so you wont have to go from website to website for information, and to ensure that you get started flying the right and safe way.

Lets start with your content, what is in the box?


Now for the fun to start, charging those batteries

The Splashdrone 3 + comes standard with 1 x Flight battery, 1 x Remote battery and 1 x  Balance Charger. Please note that you can only charge 1 battery at a time, do not attempt to charge the remote battery and flight battery at the same time.

The battery must be connected in a loop formation when charging, please see the video bellow:

Please take note of the following:

1. Lipo batteries are very sensitive and require more maintenance than any other component on drone.

2. Never leave batteries in the sun or in the car, otherwise they overheat, will lose power and swell up.

3. Do NOT charge batteries directly after flying, let battery cool down first, otherwise they overheat, will lose power and swell up.

4. Do not leave battery plugged into drone for long periods of time.

5. If you are not going to be using drone for some time, discharge batteries by 50% for storage purposes.

6. Lipo batteries do not have warranty, please test them within 7 days and should they be faulty we will replace them for you.

Please take responsibility to look after your batteries.

It is VERY important to keep an eye on your battery voltage when flying. This is shown on the remote control. A fully charged battery is 17.2V.

A low battery voltage is at 14.6V. When the drone gets to 14.6 you will see a warning come up on screen. At this stage you must press “return home” on you remote control.

When the Voltage drops to 14.4v then the drone will land automatically wherever it is. So avoid this especially when you are flying over water. If you find yourself having forgotten to return home on 14.6V and the drone starts landing automatically on 14.4v. Then you can still press return home, the drone will return as far as possible but you run the risk of damaging the battery.

Return Home Function is only accurate to 1.5m depending on wind and satellite connection.


Next, on to calibration…

This step is vitally important so please do not ever consider skipping this, it takes a minute or two and is required for your drone to preform at its best.

Please remember to do this away from cars, strong magnetic fields or electrical currents. Also, this needs to be done outside in the open air and no camera/payload release should be plugged in.

Please follow the bellow videos for your Compass Calibration (We recommend the 6 sided calibration):

In addition to the compass calibration, Gimbal and Accelerometer calibration should also be done before flight to ensure optimal performance.

Please follow the bellow videos as a guide for this:


Some Important Information:

YAW represents the compass reading within the magnetic field where you are flying your drone.

Yaw reading is indicated by the “Y” reading on the remote control.

This refers to the rotation of the drone.

Generally this should be a value between 0 and 360. Sometimes a value between -20 and 340. When the drone is stationary, yaw reading should remain more or less constant.

You can test the yaw (compass) reading within the magnetic field by rotating the drone. Rotating clockwise will increase the yaw reading up to approximately 360, rotating counterclockwise will decrease yaw reading down to 0.

When you are in an area with magnetic interference, the YAW reading could count up or down continually even when the drone is stationary.

When there is serious magnetic interference you could se ridiculous readings like 480 for example.

In cases like this you can unplug drone and replug. Also lift drone high into air and rotate until compass readings become consistent.

Just never take off with poor magnetic readings as this could cause drones to fly away.



1) Close drone cover very tightly, make sure there is no sand on any rubber seals otherwise it will not be waterproof.

2) If your accessory has an SD card, make sure you close the sd card slot properly.

3) The 8pin plug also has a rubber seal, tighten it well so that it seals.

4) When taking off the cover, make sure that water does not run off of it into the drone.


Almost done, lets go through the flight modes and some Precautions:



Last but not least…

It is important to always stay within the law, and use your drone safely and responsibly. We have put together a a rundown of the South African drone laws, no fly zones and some general advice to equip you with the necessary knowledge to play by the rules.
