20 ArduVTOL Posted by Jonathan Hesselbarth on May 14, 2013 at 6:30am We had our first fully tilted flight:More information on wingcopter.com Tags: arduvtol, wingcopter E-mail me when people leave their comments – Follow
That's a good reason, thanks for explaining.
There is so much anhedral because I want the center of gravity in the middle of the four motors. That assume that the center of pressure is just behind there too. I achieved it with the anhedral wings outside.
Without the doubt I recommend you for the best award of the year!. This can revolutionize the aviation industry. well done!
Why so much anhedral?
Why would the wings produce negative lift? I'm not quite understanding your observation yet.
Maybe this helps: the autopilot isn't being tilted during flight, therefore the virtual horizon remains the same. Using a couple of functions, the controller takes care of the changing thrust vectors depending on the "arm angle". That way the original program itself remains largely unchanged.
But yes, customizing the code was a rather lengthy process ;)
Now i see what i was missing, the quads tilting independently of the wing. Was initially thinking it was rigidly attached to the wing. Very nice concept, Jonathan
I assume there is some serious custom programming in the autopilot.
I have a technical observation please, if forward thrust is provided by the quad rotors, that means that the wings will have negative lift in forward flight as a result of the quad tilting forward which will be serious disadvantage to the system so please, am i missing something here?
I would be very interested in the horizontal flight mode figures with a 4S 5000mAh looks like there is a lot of potential here!
The wingcopter weighs 2.4 kg and has a 3S 5000mAh battery, the flight time in hover mode is around 7 minutes. In the horizontal flight mode, we should be able to stay in the air for much longer. We still have to determine how long though.
Youp, we plan to sell it =)
