Its Working

After construction and preliminary programming the motors of the quad copter are spinning.  The quad copter is a few weeks out until it is finally flight worthy.  These last couple weeks I have spent by programming the motors and the controller.  The controller is so complex, with  eight switches, you would think it be able to build a house all by itself.  lucky for me I don't need to use all eight switches. I am planning on only using two or three for the flight modes and the GPS compass.

For this week the plan is to read more of the manuals.  There is a huge step by step manual from DJI that outlines all of the prostheses needed to program, even the most complex quad copter.  And maybe this week I will start to program the GPS.  The GPS is very fragile in the way that it uses the Earth's magnetic field and satellite location to pin-point the location.  The problem with the magnetism is that the motors generate their own magnetic field, so the GPS needs to be out of range of the motors' fields.  If the motors' magnetic field does influence the GPS than it can cause the quad copter to go haywire.  After all the GPS is supposed to be the fail-safe system for when you're are going to crash.

P.S. The Video is in slow-mo, those motors are fast.
