I am going to confirm it was the ESC/BEC

Now that I have the system clamped to the work bench and running in a controlled enviroment, it still freaked out. Good thing I didn't really like that foamie.

When it went over the edge the motor would start varing in speed and then quit all together. I let things cool down a bit and was able to recreate the problem 3 times. I then went back and ran the system with only 2 servos and had no problems. The load on the BEC was minimal in my book .06a/.6w static draw from the servos, .25a/2.6w when with all servos moving.

Stranger things have happened. I guess it's off to Hacker to try to get a replacement or run a UBEC
