** 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 monitor antennas. Your kit is packed in bubble wrap and the box padded out with foam chips to ensure a safe trip to your door.


* IMPORTANT – You must calibrate your 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
  • Transmitter, manual and charger
  • 2 x Spironet Antennas (for QuadH2O and monitor)
  • Patch Antennas (for monitor)
  • 1 set of props
  • Spare props (if ordered)
  • Carbon monitor mount – you will need to assemble this
  • Monitor with integrated battery and sun hood, manual and charger
  • BTU Manual (if ordered)
  • OSD manual (if ordered)
  • Charger, manual and leads (if ordered)
  • GoPro (if ordered)
  • Waterproof gimbal (if ordered)
  • Sticker Kit
  • Naza assistant lead (not required if BTU ordered)
  • Various leads for Monitor (spares)
  • Silicone Grease (for dome seal and spitzer o-ring)

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).

1. 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.

2. 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.

3. 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.

4. Remove the QuadH2o dome and plug the Naza 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 Naza assistant software on your PC)

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

The default password set up on the BTU module is 123456

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

6. Double check all the Naza settings in the assistant software and ensure you are happy with them (specifically check the operation of the flight modes, failsafes etc.)

Within the Naza assistant software you will find the ‘motor test’ function (this allows you to confirm the correct motor rotation/direction). Refer to the Naza manual for more information.

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 Naza manual), the motors should start, 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 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).

Hitec Flash 8 TX Settings:

Charge the Radio Transmitter using the supplied charger inside the box.

Your Flash 8 transmitter has already been bound and configured to your QuadH2o/Naza, there are several switches and one slider activated on your TX.

Switch E: this controls your flight modes : GPS/ATTI/FAILSAFE – (forward/up is GPS)

Note: Failsafe is also configured on the TX, so should you lose TX power, turn it off or go out of range your QuadH2o will automatically go into Failsafe mode.

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

Note: Refer to the Naza 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.

Switch RS: The ‘right slider’ switch controls the gimbal pitch (if ordered)

Switch B: If you have ordered the waterproof gimbal, switch B will enable you to remotely switch between the FTP camera and the GoPro.

Switch G: this controls the Intelligent Orientation Control (IOC) flight modes : Course Lock/Home Lock – (forward/up is OFF)

Find out more about the IOC modes here

(Even though we test the failsafe and flight modes before shipping your machine, 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.

iPad Ground Station add-on

If you have purchased the iPad Ground Station, the air module will be installed to your QuadH2O. You will need to setup the ground end and configure with your iPad (please refer to the iPad Ground Station manual for further setup information).

Waterproof Gimbal add-on

If you have purchased the waterproof gimbal it will come pre-installed and configured. Carefully insert your GoPro camera, ensuring not to pinch the GoPro data cable when closing the waterproof housing. When you power on your QuadH2O ensure the gimbal is the correct way up and facing forward (if not, when you power on your machine the gimbal may not complete its start up procedure correctly and may be out of line).

If this happens, power down the QuadH2O, straighten up the gimbal and power on the QuadH2O again.

NOTE: IT may be require to re-calibrate the gimbal after shipping or heavy landings. If you beleive re-calibration is required, please refer to the gimbal manual.

When ready to fly for the first time:

Fit the props ensuring they are fitted correctly
Calibrate your compass! (please refer to the DJI manual)
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. You can do this by gently breathing through the breather pipe, pressure build up indicates you are air tight etc. (you can also use some soapy water on suspect areas if required to check for leaks).

Your kit comes with 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 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 the supplied 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 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.
