I got the rotorgeeks 12A ESCs (v4) and they work flawlessly on my 4S quad. I didn't even have to calibrate them. Hit the mark right off the bat.
Service and delivery from Canada to Massachusetts...
I bought a set of motors and sat on them for an entire year. Upon install I realized one of them missed the threading process. No worries! Rotorgeeks still sent me a free replacement after a whole yea...
Great products, great prices, great communication.
