+1 on the 120 amp turbo esc. It has excellent power and smooth throttle response. I've run it in several cars including a 4x4 sct (hyper 10sc). It pushed a 4800kv 4 pole 550 motor with no problems. Make sure to get the proper programming card with it so that you can adjust everything. Both are available from the US warehouse so no long wait to get it. Best budget esc out there IMHO.
