Here are the motors, after attaching the included bullet connectors. Two of the motors are spares. We've got two spare ESCs as well.
Here's everything wired up... 4 motors, 4 ESCs, 2 power distribution points, power cable. The small box is my servo tester, which since it basically drives a PPM signal is great for testing motors too.
Everything seems great when run without load (i.e. no props). Soon I'll have the load data, including thrust. If I can figure out a good way to attach it, I'll hook my thermocouple probe to my arduino kit and measure the ESC temperature as well.
Here's what the final propulsion system looks like:
