I think I lost my DD motor today. Either that or the solder joint went bad. I didn't crash, though. I was only a couple of feet up and able to just do a piro landing. The revo mixing was just starting to get dialed in on my 9C, and i changed lipos, took a break and then went at it again. It was a couple of minutes into the second flight that the motor went bad. Oh well, time to heat up the soldering iron....
