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

Max,
It's a shane we didn't get a chance to hook up when you were in Melbourne.
Let me know when you ae coming back to town and I'll take you out and show you the Devil Ray in action.
Cheers!
Scott
I would be willing to sell CAD files. There would need to be a non compete agreement and or licensing agreements made but it could be worked out. The Skywalker has proven to be a decent aircraft. Not sure about endurance but I have been told you can fly it for up to 1hr. IF I was to buy one I would design a new wing set for high endurance.
We have had a huge jump in interest in the Devil Ray and its various sizes. I do not want to clutter up or break rules advertising on the forum so please feel free to contact us anytime.
I warn you the aircraft are not cheap but you get what you pay for!
Thank you,
Chris McNair
@Chris
Have though about selling CAD files?
May be a bit off topic but:
Since I'm in hobby budget constrain, but looking for long flight endurance,
what do you think about the Skywalker on GF as the one sold by HK ?
I am looking sth easy to fly, roomy and long endurance (super maneuverability isn'y on top of the list),
sth to move up from EasyStar like plane
You could get the Zeph to fly for 2hrs but there is no where to put all the electronics and batteries!! I think the Zeph is a great learning/training platform.......
I sure wish I could get the cost down on our aircraft but facts are man hrs eat up a lot of $. If done correctly the composite materials alone can cost more than a loaded Zeph....
Love that plane Scott, wish I could have been there when you flew! :(
I think the main difference between these wings and "foamys" is endurance. Theres no way you will get a zeph to stay up for 2 hours.
There are retracts for the Devil Ray available.
@Doug
how about the camera(s)? Trappy's FPV cam at least sticks out of the nose.
Have u got any link photos of those setups?
