Yep, found it. You are correct they are SUPER hard to see in blinky mode. Ok, so all three LED's do indeed flash when turning the motor so the wire and motor sensor appear OK.
As a side note when I took the esc out of blinky mode and ran it through the throttle the motor sounded smoother even at higher RPM. In blinky mode the motor sounds "rough" so to speak (even at full throttle).
Weird...
