But all it does is let you run a high current drawing motor. Which, in my opinion, isn't needed on a track that's any more than an oval or a drag.

If your FET blew all on it's own and you *have* to replace it, that's another thing altogether. I commend an attempt to fix something rather than replace it.

Seems to me though that most people think stacking fets will make their car faster, or is necessary to go fast, and that just isn't true.
