Smarter Cheaper Faster

Hi Guys!

 

If you have not seen this yet check it out!

 

It is the Devil Ray 2.4M flying wing  made by Chris McNair.

We asked him to make one for us to use in the Australian Outback UAV Challenge. And before you ask we have an ATTO IMU onboard!

The Devil Ray has the option of 3 different wing sets 1.8m, 2.4m and a 3.6m. (We have the 2.4m)
With all the extra gear needed for the OBC, PTZ camera, 500ml water bottle, failsafe systems, transmitters, modems etc..
We loaded it up to 6.75Kg total weight. With all this extra crap on board it still had a easy take off and climbed nicely.
I still remember being impressed that even in manual mode (just over half throttle) it was doing 90-100Kph and was only pulling 15 amps.
(This is better in Autonomous!) We have a 6S 10,000mAh pack on board.
It has a very large speed envelope and handles great in the air.
The marked CG point was perfect and there is heaps of room inside which made it easy to balance. Landing speed is a crawl and has proved to be easier than the 12’ Telemaster to land.
I have an attached a couple of photos below.
I know Chris has refined the design (since making ours) and is now selling them with multiple options ranging from marine application that is water proof to a retract landing gear option for clean smooth flight.
The fixed landing gear option is nice but does add a bit more weight due to the very large wheels for our flying fields.
The Devil Ray is definitely worth having a look at if you are in the market for a high efficiency flying wing with a very large payload bay.
It also brakes down into a nice size carrying case or box.

 

If you like what you see you can contact Chris at chris@attopilotinternational.com as they are now available.

 

Cheers
