PH145 Brushless FPV Quadcopter

The PH145 quadcopter was inspired by the [RS90](http://www.thingiverse.com/thing:1596739) and [DJ105](http://www.thingiverse.com/thing:1580385) brushless quadcopters. The RS90 looked like fun, but the DJ105 wasn't much bigger and produces a lot more thrust. The DJ105 uses 2.5 inch propellers, and I quickly learned that these are rare. 3 inch propellers are available everywhere, and there's a much bigger selection of motors if you build a little bigger than the DJ105.
