openDog V2 Part 2 - Building a test leg

It's time to build the ultimate robot dog using the R&D from my previous builds. This dog will use Quasi-Direct Drive from large diameter low KV brushless motors so that we can make the joints dynamically compliant using the same method as my previous back-drivable test dogs which worked well. I'll then add the some of the dynamics I tested in the miniDog series. This time I'm building a test leg, using two Turnigy Multistar 9225 90 KV motors controlled by an ODrive, I'm testing out the load a single leg
