I didnt want to hijack someone thread but I just wanted to share this, I was taking video of fireworks near the lake, The first battery went fine, but the second battery just went crazy after launch with compass errors and such. After a big fight with it, I managed to get it back in one piece without going into the lake. If someone could just take a look at the log and let me know what happened. Thanks. 81.83 mph is that some kinda record?!
