Introduction to the Orange Hawk Project from Stephen Carlson on Vimeo.
Presented here is a VTOL aircraft design that I've perfected over 16 months, and intend to release as an Open Source project with design plans and code. Initial details:
Wing Span: 1000mm
Area: 21.5+2.6 dm^2 (Elevons)
Quarter-Chord Sweep: 30.0deg
Airfoil: MH45 with Root: +2.0deg Tip: -0.5deg
Material: 21.0kg/m^3 EPP
Equiv. Rotor Diameter: 500mm
Flight Controller Based on MultiWii 2.1
All-Up Weight: 1.2 kg, Theoretical Maximum: 1.5 kg
Designed Fall 2012
Well done !!!
at the beginning of your video I noticed two
screen shots of modeling software
could you please post what they were
Maxime: The problem with making the rear motor tilt backward/down is that it would be setup for the wrong direction of thrust as is. It would have to do one of two things to be feasible. The easiest option would be to start it with the motor upside down relative to what it currently is. That would be a whole host of problems, but when tilted backward/upward it would be thrusting in the right direction. The other option would be to use a VPP on it. When you tilt backward, flip the pitch. This would be an added pain, it would limit your choice of motors, and it would require the weight/complexity of another servo. However, you could do really cool things with it while the mains are at a 45-degree angle!

Also, I've given the folks at RcGroups an exclusive look at some of the code, since the text editor here does not play well with posting raw code snippets:
This is a screen shot of the MultiWii 2.1 GUI I've modified.
Update:I've decided that I may create a blogspot page for this project, similar to what William Thielicke has done with his project: http://shrediquette.blogspot.com/ . I've attempted this sort of thing before here: http://sc-uav.blogspot.com/ , but may elect to move to a Wordpress template. Whatever is most effective and saves time for the stressed-out college student.
Back to homework.....
