ESC Blues

Guys, feeling a bit dumb and may have prematurely posted. I updated the Castlelink software which THEN revealed a more recent firmware update and I loaded it. Cogging reduced to very brief pulse while it seeks the motor position. Still not nearly as good as a Quark but may be manageable. I am using a BEC. The thing gets hot, no doubt about it. It was a new ESC. My last CRT was designed for the chassis to heat sink everthing and nothing ever exceeded 35F over ambient so perhaps this heat is normal. I don't like normal though and will add a fan and/or mod the heat sink. Why oh why has it taken so long for a real 1/8th controller? Thanks for all those who gave feedback.
