Why do you say it needs a better FET? What's the build you're trying to make?
The stock MOSFET does not make a full cycle if you don't hold the trigger down slightly longer than other MOSFETs. If you tap the trigger, a partial cycle occurs. It is a known problem on these KV's. I think aftermarket companies will a opportunity to fix it.
If you see someone with a KV gen2, give it a try. You will see how bad it is.
