For some reason the ESC doesn't like the signal from the Unichip. One thing I noticed when controlling the ESC with the servo tester is that it sometimes but not always seems to have a boot up delay with a beep the first time I speed it up after its powered on.

My best two recommendations are 1) getting it on a oscilloscope to see what the signal is actually doing and 2) using a buffer to make sure the signal is clean and the proper voltage. #1 is probably going to be the best thing. The signal is likely just doing something weird that the servo is able to compensate for or just not care about while the ESC gets pissed over. Without seeing the signal you don't really know what its doing for sure.
