Alexmos RC input control video http://youtu.be/xQSYgZHvQwA Alexmos settings info at youtube link. Blog Post: http://paralluminati.blogspot.com/2014/04/compact-2-axis-gopro-gimbal-guide.html This was designed for the small volume of a plane's nose cone and based on the alexmos simplebgc hard/software. I documented the motors used already in my skeleton gimbal build.(http://www.thingiverse.com/thing:310676) I got the board for $60 on ebay, from China of course. I like this design but I am wanting to design a tighter one that uses some gears...more to come. ** this version has a holder for the MPU6050 accelerometer which is typically standard with the alexmos hardwareSame ole song and dance, M3 hardware. Fill 0.8 Height 0.2 PID's are lower and more conservative.
