Frequently asked questions

Is the SARAH2O waterproof?

The SaraH2O is designed and developed to be a sealed, water tight unit, with exception of the two breather tubes (which allow the barometer within the flight controller to measure outside air pressure, and are designed to let air in/out but not water) and the motors.

The brushless motors are exposed but can run if wet (and even underwater), however we recommend you rinse them with fresh water after exposure to salt water to prolong the motors bearings.

What's It made out of?

The body is made of Epoxy fibre composite which makes it very strong, lightweight and rigid.

The viewing dome is perspex whilst the rear hatch and various internal parts are 3D printed.

Will it work with the DJI Naza & GPS?

Yes, in fact, we have designed the hull specifically around housing the DJI Naza & GPS.

Can you recommend Gains settings for the Naza V2

These are a good starting point: Pitch:200% Roll:200% Yaw: 150% Vertical: 100% Atti Gain: 80% & 80% and are the settings supplied with the SARAH2O

Can you give me the GPS location settings?

Presuming you fit the GPS in the specified area, level and facing forward, they should be: X = -5cm | Y = 0 | Z = -8cm.

It's a sealed unit...Doesn't it overheat?

We have tested the SARAH2O in ambient temperatures of 38 degrees. The external heat sinks on the ESC's and internal fan keeps things cool and circulates the air inside.

What flight times can I expect?

This will greatly depend on your setup, battery, internal components, payload etc. However based on our recommended set up (which you can find in our build guideline) you can expect 20-25 minute flight times on a 2 Lipo setup and approx 15-17 minute flight times on a single Lipo setup.

What size battery can it take?

We have run tests both with 1 and 2 6S Lipos ranging from 6-8000mAh. The HexH2O has a large battery compartment with inside dimensions of L180mm x W130mm x H100mm, aperture: 120mm x 90mm.

Longer flight times could be achieved with different weight and capacity batteries.

With 2 x 7000mAh lipo’s you should expect between 202-25mins flight time (depending on flight conditions)

How big is the SARAH2O?

The overall size of the SARAH2O is L650mm x W740mm x H240mm (unfolded).

The body size is L400mm x W380mm x H150mm.

Transport (box) size (when folded) would need to be W750mm x L380mm x H240mm (internal dimensions). We recommend and can supply the Peli 1730 case.

What does the SARAH2O weigh?

When fully loaded with 2 x 7000mAh Lipos, GoPro, gimbal, downlink, OSD and Flir camera the SARAH2o weighs approx. 5KG.

Does the SARAH2O have a live video feed?

Yes. Video is transmitted from the GoPro and FLIR camera (if applicable) directly to the monitor attached to your transmitter on the ground. You can switch between video and IR video feed via a switch on your controller.

What IR cameras are compatible?

Both the FLIR VUE and FLIR VUE Pro are compatible.

Is the FLIR housing waterproof?

The FLIR housing should not be submerged in water. It is designed to be weather resistant so can be used in the rain or snow.

Is the FLIR housing adjustable or removable?

Yes you can manually adjust the angle of the FLIR housing. The FLIR housing it also removable via the GoPro style quick release mount.
