Today everybody and their dog seem to be working on a quad project. And with my own quad having reached a relatively mature stage with stable flight some time ago, I thought it would be nice to try something different.
So inspired by the full-size Osprey tilt rotor design I just started an experimental duo/tilt copter build. Frankly I am far from sure if it will ever fly, but that is what makes it fun!
Mechanical:
My tilt design is one I used in an earlier tri-copter build. I insert a 8mm CF rods into a 750x10,5mm CF square tube and glued then together. A modified T-Rex 600 blade-holder is then inserted on the 8mm tube and fastened using glue. Finally a servo is epoxied at the side of the square tube and linked to the 600 blade-holder. Motor and ESC is a cheap TowerPro combo from HobbyKing. Cheap and easy to replace when experimenting, and the ESC has no problem handling 333mhz PWM pulses.
Hardware / software:
For control and stabilization I will use the same hardware that I used in a Quad I built earlier. A FASST R617FS receiver modified with PPM output, and the ArduIMU V2 board with custom software for stabilization and servo/ESC control.
Main body / tail:
I have yet to decide what I will do for a main body. At the very least I will need some kind of tail with a lift surface to get some balancing momentum in the pitch axis, and tail drag when in forward flight. Lots of fun experimenting to be done!

Do you plan to have normalish airplane hull or what on this?
