I am using a 3s and when it's switched on, I get the 3 beeps indicating 3s.

Just tried the following on recommendations:
-Changed the LVC to Disabled, then tried Low (Default is medium)
-Changed the ESC Thermal Protection to High
-Disabled the Motor Thermal Protection (Default was 2 beeps)
-Changed the LiPo Cells from Auto to 3 cell

Unfortunately none of the above works. Appreciate the tips though.

I am sure there is a combination to get this working again.
