I have had a Havoc Pro SC X-Drive in my stadium truck paired with a premium Ballistic 10.5T for over a year. It has been flawless and runs great.

I put a new Pulse in my new Custom Works sprint car with a Ballistic 7.5T and it too is awesome. All the power I need (plus some) and it doesn't get hot during a run. Plenty of room/power to play with still. I liked the Pulse so much that I bought one for my EDM and a 7.5T w/ a 12.5mm rotor to replace my Castle 4600 1406 and MMP.

I still have my first ESC ever: a Novak Fusion dual-profile that to this day, still runs like a top. I bought it nearly 12 years ago.
