    could you please post what they were 

  • Pretty neat!

  • Awesome!

  • Great work!

  • 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:

  • 3692657151?profile=originalThis 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.....
