Just thought I'd give some feedback on the Wire library. The modified speed controllers that we use worked fine with it, still have some issues, but I'm not sure if that's with the library.
Here's a video of a little of the testing we did, note that the video is shot because the LiPo battery was going flat, also the maple isn't controlling the motor in this test.

The issue encountered was when I removed the battery and plugged it back in, the motors didn't spin up again. Not sure why this is, seems it's getting stuck or something. I'd say we're about a week away from flying, was hoping to achieve flight on the weekend but had some issues.
