Cogging and flashing yellow LED

Yeas to this first, the second I haven't tried.

It may be a few days before I get around to it. After having two ESC's dump on me over two days, I need some cooling of time so I don't do anything rash.

Tried it without a servo connected with wheels of the ground, it still cogs but the yellow LED doesn't seem to come on anymore.

Hmm come to think of it, i did update the ESC to the latest beta. It didn't do the cogging thing before doing that.
