It´s been two months since we posted our first flight report; time for an update!

Here's what we've been up to:

As you may have seen on Chris Anderson's Blog, our Wingcopter now uses the APM2.5. The agility and stability seems much better compared to the old APM1.0.

Above is a video of one of the longer flights, including some maneuvers:

When there´s no wind, the wingcopter performs just as expected/commanded. However, in turbulent air the flap's control commands are still slightly too extreme. It wobbles a little bit. In order to solve this problem, we'll have to play with our PID Parameters again.

In last report's comment section, there where some question concerning flight maneuvers. As a result, we tried out to tail sitting and landing as a conventional plan.

Tail sitting is possible, but it´s not as easy as we initially thought it would be.

We tried to land in "conventional plane mode" at the end of this video

 

and this one:

slightly harder landing than intended ;)

We also tested the maximum payload. After a couple of increases, we tried a 636g beer bottle

At this level of payload, the plane is harder to control, especially if there's a certain amount of wind (like in the video). So far, we would prefer up to 400g of payload, as the plane's behavior changes very little compared to flights without any payload.

We hope your enjoyed our little report.

Andy and Jonathan

  • Thanks for the graphs.

    So its seems that it uses 1/3 consumption than in the hovering position. 

     Great job  IoI.

    What it the flight speed?

    I think that http://www.vtol-technologies.com/flying-wing.html have patented this VTOL.

    I also found the link https://www.advancedtacticsinc.com/technology/barracuda/ which looks similar.

    What is the difference between you design?

  • Hi! WingCo%20V13CH%20(5).png

    Above you see the current draw (red) and the throttle position (blue) by 3S voltage and 2.4kg take-off weight. It is an old measurement of one of the first prototypes which lot of potential to optimize. The newest version called Songbird (link) with 3m wingspan, 8kg take-off weight and 6S lipo for example has much better current characteristic in forward flight.

    Forward flight is controlled by flaps and dependent on the code setup also by motors. We have there now an own FC which just use the Pixhawk in ff for waypoint navigation.

    @Raymond: The V13CH carry up to 1kg payload. Flight time is around 20min. The Songbird is there much better. It stays up one hour with one kg payload. Theoretical, full with batteries, it should stay up even more than 3 hours.

  • What is the throttle percentage during horizontal straight and level flight?
    And how much during hovering?
  • How do you control it in horizontal flight?
    Only with the motor?
    Did you published the code?
  • What kind of payload can the wingcopter hold? Would changing the motors/props help?Whats the flight time?

  • What a platform!!!!! Great work!!! 

  • I congratulate, very good work.

  • Is it possible to get the code you are using ? It would be greatly appreciated 

  • Hi! We are using a changed Arducopter version. Like you supposed the props are controlled during forward flight too. Theoretical it should be possible to fly the wingcopter in plane mode less the flaps.
