ive tried the 10a esc already there naff, the ones with a brake just stop if you try to go from full forward to revers until you center the stick and put it in reverse again and if you get the version without a brake and use a mixer it tends to twitch when your not touching the controls and 1 side will drive a bit faster than the other

also if you over volt them to a 3s lipo they get warm very quickly
