Simple Phantom Rail System

I want to make my DJI Phantom something of a utility vehicle with swappable under carriages depending on what I was needing it to do. I also wanted the attachment part on the Phantom had to be very light to make the most of my battery time just when I want to fly for fun with nothing on it. Here's what I came up with. I will also be posting a gimbal mount for this rail system with more to come.
