Incomplete soldering causes the board not able to communicate with ESC's. This causes me to spend so much time on troubleshoot ESC calibrations. I thought that the MultiWii program setup and parameter settings were the issues. It ended up the board defect.
The entire 3rd row of the ESC pins (signal pin) didn't solder to the board. See the arrow shown on the picture below.
