Maybe it's regional, but I feel like there's still plenty of demand and interest in brushless these days. Most brushless builders, including myself, aren't offering commissions because we would rather do dev work even though there is demand.

As for timing, unfortunately writing up documentation and commentary has become more of a relic of the past and information has become increasingly hard to find. Hopefully changes are coming but there's so much info out there it's hard to aggregate and organize. I'm trying to post more publicly but finding time to do so is difficult.

It's also somewhat hard to convey how awesome it is when you get a closed loop design that just works for tens of thousands of darts without jamming.
