OMG a rotorplane!

Also, do you have any specs on loiter time based on a specific battery size with takeoff/landing included? This seems like a really interesting alternative to parachute driven fixed wing craft.

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 =)

I would be very interested in the horizontal flight mode figures with a 4S 5000mAh looks like there is a lot of potential here!

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 assume there is some serious custom programming in the autopilot.

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

@Yusuf Onajobi:

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 ;)

Why so much anhedral?

Without the doubt I recommend you for the best award of the year!. This can revolutionize the aviation industry. well done!
