I'm running a duty cycle signal at 50hz from the Unichip to the ESC. 5% -10% Duty cycle (1-2 ms on ). This should be about the ideal servo signal. If I connect a servo to the Unichip instead of the the ESC it controls it perfectly. When I connect a server test box to the ESC it will drive the motor just fine.

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.
