I just spoke with Tracy and came away with a few nuggets that others might
find useful... and might save him a few phone calls :)

1. EM2 voltage calibration is * 10 - i.e. you want a high alert at 15V, you
set it at 150. Who knew? Everyone but me, it seems :)

2. Autotune upgrade availability will be announced as soon as he's done a
few more verification flights. It's field chip upgrade to the EM2 only. No
changes required to the EC2.

3. A slight "chatter" from the redrive is normal at very low rpm  (phew!)

Hope this helps keep people off his back while he fixes my bad EC2 chip :)
