Awesome, I'd love a closer look at the tilting mechanism in action (on the ground maybe?). I like how you avoid having to reverse the prop direction. The transition from hover to horizontal flight seems very smooth.
When are you going to post a Kickstarter project? :)
All 4 motors can tilt up to 90 degrees. For hovering, the motors are tilted as shown in the picture above (we refer to it as 0 degrees-tilt-angle); All of the 4 motors contribute to the "upward thrust" and keep it hovering.
For horizontal flight, all of the 4 motor arms are tilted 90 degrees; that way all 4 motors provide forward thrust. We are working on a new blog post atm, should be up in a few hours; it will include a video of the tilting mechanism that should illustrate what I tried to describe.
Today we tested hover flight time and payload. The Wingcopter hovered 8:20 minutes (without payload) and was able to carry a weight of 540 g without any problems. Next time we will try to figure out the maximum payload.

wow, nice tilting solution!
i had thought about doing someting similar with a tricopter, but never figured out how to adjust the CoG. this is really incredible.
Nice design! I'm interested how you reverse the thrust of the rear motors from pull in the vertical position to push when rotated? Special props?

Very cool! Out of curiosity, what angle forward/back can the motors tilt? Can all four motors tilt (or just two)?
It can glide in the horizontal flight with motors off. To land so should work, but I am not sure if I want to try it.
We are using the APM.
how much $$$?
This is brilliant, congratulations on the development.
Its like the quadshot http://transition-robotics.com/ but has different capabilities and will have different uses. Are you using APM or paparazzi?
Once you have it in horizontal flight could you turn mothers off and glide in for a landing?
Also a mode of horizontal flight where two rear motors are off and two front motors flip into horizontal position
for faster forward flight.
Looks really cool.
