I upgraded my WKM to 5.06 on Monday thinking I might see an improvement in stability with my heavy lift AD6, after checking and double checking everything I took the rig out on Tuesday for a test flight, all looked fine for the first 5mins but then I noticed that in forward flight altitude hold wasn't very good so brought it back to land. As I got back to a hover it slowly started to drift backwards so I compensated with forward stick (now in atti.mode) I quickly switched to GPS atti. mode to see if this would help but no change, at this point I was full forward stick but the hexa just kept increasingly pitching backwards to the point where I had no control so I had no choice but to bring it down hard and fast from about 12 feet resulting in a damaged skid (really lucky there was not more damage). I immediately removed the dome to get a quick look and do some crash investigation, I immediately noticed the ESCs were really HOT!!! Noticeably more than normal, as were the motors. After repairing the landing skid I reverted to 5.02, tested everything without props and then took her back out yesterday for a test and everything was back to normal. I'm not touching 5.06 with a barge poll, has anyone had similar problems?
