Anyone got problems with hot motors, ESC, or crashes on 5.14a? 3 of us in So Cal that upgraded to 5.14a crashed our birds last week. I was the first to crash and initially thought it was battery low but after checking the battery at home, and after 2 others crashed the same way... we are thinking it's ESC overheat and it shut down the motor. Just noticed someone over at RCgroup (http://www.rcgroups.com/forums/showthread.php?t=1486386&page=1015#post22685549) also had a crash the same way. Just wondering if anyone else have the same problem.
I talked to DJI China a few times... they are advising to use DJI ESCs (i'm currently using Maytech 35A V1) with AVROTO M2814-11 motors. They also advised there are no changes to motor control in 5.12 or 5.14a. But I noticed motor 1 and 3 gets warmer than 2 and 4 pre 5.12 and after 5.12, 1 and 3 gets HOT. Also... after taking my bird apart (as well as one other crashed CX4 on 5.14a)... the shrinkwrap on the Maytech burnt through displaying overheating symptoms. (see pic).

Below is the video of my crash on 5.14a. twitched twice and motor 3 shut down and crashed. My guess is the weather (being too hot) combined with ESC overheating shut down the ESC and motor.
