ArduVTOL - Wingcopter - Flight Report Nr. 2

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.

Regards

Andy and Jonathan

PS: our wingcopter is now available on our website!

Congratulations - looks really good!

Great design and seems to work and transition very well now.

A lot more practical (and probably more useful) than the Osprey.

jonathan fine, I like that the project is progressing.

Wow, very cool!  Do you use Arducopter, Arduplane, or your own custom firmware?

Once you are in plane mode, do the props become "locked" to one throttle, or do you vary them for control?  For example: to yaw the plane right you would increase thrust from the left side motors.

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.

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

I congratulate, very good work.

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

What kind of payload can the wingcopter hold? Would changing the motors/props help?Whats the flight time?

How do you control it in horizontal flight?
Only with the motor?
Did you published the code?
