** Please read this guide in full before using your QuadH2O **

As part of your RTF QuadH2o build your quad will have been bench tested to ensure all components are functioning correctly.

We test the video/FTP link, Naza flight modes and failsafe switches, set gains, check motor rotation OSD* & BTU*. We also test the wiring loom, motors and ESCs.

*If ordered

You may find you want to fine tune your gains to suit your own flying style, but our base settings are a good starting point for your QuadH2o.

When we ship the QuadH2o we remove the props and Spitzer (battery) cap and the antennas.


* IMPORTANT – You must calibrate your flight controller IMU and Compass before you fly for the first time.

When your kit arrives:

As per our T&Cs the first thing you must do is open the box and check your kit has arrived safely. It is very important that you notify us by email within 24hours of receiving the kit should the unlikely happen and it arrive damaged.

What’s in the box:

You will receive the following:

  • The QuadH2o complete unit
  • Spitzer (battery) Cap
  • Radio Transmitter
  • 2 x Spironet Antennas (for QuadH2O and monitor)
  • Patch Antennas (for monitor)
  • 1 set of props
  • Spare props (if ordered)
  • Monitor mount – you will need to assemble and fit this to your Radio Transmitter
  • Monitor with integrated battery and sun hood, manual and charger
  • BTU Manual (if ordered)
  • OSD manual (if ordered)
  • Charger (if ordered), manual and associated leads
  • GoPro (if ordered)

What you will need to do BEFORE you fly:

Before you fly your QuadH2O please follow these instructions carefully; Ensure you have read and understood the DJI flight controller manual and understand its operations/functions. Get the manuals here.

We also recommend you read through our QuadH2o build guide – this will give you a good understanding of how it was built and what components are inside your machine (and what they do).

Carefully unpack your QuadH2O. Check the body to ensure it has arrived safely in transit. Lay the contents out to ensure all parts are accounted for.

Assemble the monitor mount and fit it to your transmitter. Then attach the monitor to the mount.


Please note monitor mount picture may vary to the product supplied.

Before powering on the QuadH2O or the monitor, you must first fit the white square patch antenna and one of the Spironet antennas to the monitor and the other Spironet antenna to the QuadH2O.

Never power up the QuadH2O without the Spironet attached as it may damage your video transmitter.

Connection to Assistant Software:

Remove the QuadH2o dome and plug the flight controller into the assistant software* using the lead provided, then plug the other end into your PC (you will need to ensure you have installed the assistant software on your PC)

*NOTE if you have ordered the BTU module you can check the flight controller settings via your iPhone. There is no need to remove the dome or plug the flight controller into a computer – please refer to the BTU manual for more information.

The default password set up on the BTU module is 123456

Power up the Radio Transmitter and then your QuadH2o (always power on the Radio Transmitter first)

The drone will connect to the Assistance Software, from there you can check settings and adjust flight gains etc.

Once you have completed your checks remove the assistant lead (or close down the BTU iPhone App) and bench test the QuadH2O .

IMPORTANT – always test your QuadH2O with the props off

To bench test your machine, initialise motors (as per flight controller manual), the motors should star; motor 1,2,3 and finally motor 4, then move the throttle up to around 55-60% and you should hear the motors speed up automatically (this is the auto auto take off feature), check for correct rotation and correct motor/ESCs functionality. Also check your video link to monitor. Check the OSD data is on screen (if OSD ordered).

Also check the switches on your Radio Transmitter to ensure you are able to select the the flight modes (GPS and Atti mode) and also ensure you are able to activate the RTH/Failsafe feature.

If in the unlikely event of a component not working as expected/arriving faulty, please do not make any changes to the configuration of your machine. Get in contact with us, with details of the issues you are facing and we will advise your accordingly. Please note all components must be checked BEFORE you attempt to fly the QuadH2o (please refer to our T&Cs and limited warranty policy).

Radio Transmitter settings:

Fit batteries to your radio transmitter (not included).

Your radio transmitter has already been bound and configured to your QuadH2o, there is two switches activated on your TX (switch configuration will be provided with your drone depending on what radio transmitter has been supplied).

Flight Mode switch. initiates GPS/ATTI/*** flight modes (forward/up is GPS)

Return To Home switch. Initiates return to home feature (if available with your configuration)

Note: Never drain your batteries to below 20% / 3v per cell as this will damage them and shorten their life.

Note: Refer to the Flight Controller Manual for details on how to configure the voltage monitor feature.

Note: If we have supplied flight batteries, they will take several charge cycles before they are working to full capacity. You may find the first few flights are shorter than expected.

(We recommend you test and familiarise yourself with ALL settings before flying)

IMPORTANT: As a safety measure, we recommend that before each flight ensure all switches on your TX are facing up/forward. This will ensure that you are not in failsafe mode and your flight mode is set to GPS.

BTU add-on

If you have purchased the DJI BTU add-on please refer to the provided instruction manual regarding connection via your iPhone. The default password set on the BTU is 123456.

OSD add-on

If you have purchased the DJI OSD module, it will come installed and ready to use, the OSD information will be displayed on your monitor.

When ready to fly for the first time:

Calibrate your IMU! (please refer to the DJI manual)
Calibrate your compass! (please refer to the DJI manual)

Fit the props ensuring they are fitted correctly
Start with some gentle flying, get used to its characteristics and adjust gains etc. to suit your requirements (if required).

Water Test – Before flight over water:

Your QuadH2O has been sealed, however the removable areas (dome and battery compartment cap) need to have grease applied and should be checked before your first flight over water and periodically therefor after. We recommend using silicone GREASE which must be applied to both sides of the domes rubber o-ring, ( this should be re-applied periodically and/or if you remove the dome at any time). The Spitzer cap (battery compartment cap) will also need silicone GREASE applied to the rubber o-ring and thread before you install it and again re-applied periodically.

We advise you seal around the base of the grommets in the arms with silicone GREASE or marine grade Sealant.

Ongoing maintenance:

As part of your ongoing maintenance to your QuadH2O please ensure you regularly check for software updates for the electrical components (please refer to operation manuals) such as the flight controller.

Periodically check that the machine is watertight – this is best done in a controlled environment (such as a bath or pool). Seals should be periodically checked and silicone grease re-applied. We recommend that the motors are rinsed with fresh water after exposure to salt water (just as you would with a outboard motor or Jetski).

Motor bearings should also be periodically checked and replaced when required (especially after prolonged exposure to salt water).

Please note whilst great care and attention is given to the build of your RTF QuadH2O, it is your own responsibility to check the configuration, airworthiness and watertightness of the machine before you fly.


  • Check all items received in good order (within 24hours of receipt)
  • Download the flight controller manual and any other relevant manuals from our downloads page; familiarise yourself with their functions.
  • Check configuration in the DJI Assistant Software.
  • Bench test (with props off!)
  • Complete a water test
  • Calibrate IMU
  • Calibrate compass
  • Go Fly!

Important notes:

Please note whilst great care and attention is given to the build of your RTF HexH2O, it is your own responsibility to check the configuration, airworthiness and watertightness of the machine before you fly.

We recommend you allow your QuadH2O and its components to cool between flights. Removing the rear hatch between flights is sufficient.

When you receive your RTF QuadH2O please ensure you thoroughly check all parts and components as above.
