I just got a replacement from Castle and their excellent customer service and I notice that the brakes are much smoother and doesn't lockup like before. Also it is smoother on takeoff in the low throttle takeoff. Thanks Castle for the excellent customer support.
Sounds like you have the latest firmware update on that esc. I have noticed similar improvements when i updated the my MMM escs. Glad to hear castle took care of you!
I noticed the same w/my new monster controller vs. the old one I blew up
It is amazing how smooth these controllers really are
