this is my first brushless gimbal for a mobius camera. the motors and the controller are from rctimer: the design is pretty simple, just print the three arms, insert the ball bearing, attach the motors and the motion sensing unit. upload the software, choose the correct motor number ant their rotation direction, then adjust the pid settings... finding the correct pid settings caused a bit of a headache. the creo elements express (free 3d cad) file of the entire assembly can also be downloaded in case someone wants to modify the design.
