Way back, maybe 30 years ago, when Novak first started---and even earlier when Bob worked for Micro Avionics and then Orbit, there were companies that kitted up parts for electronics. I think Ace and Royal Electronics sold servo kits and probably receiver kits.
I don't remember anyone kitting up speed controls. Even the earliest Mosfet escs--for cars-- in the early 80's were pretty challenging. I do remember when a Novak employee---Eloy Marez, who wrote articles for one of the airplane mags, did a piece on building a simple esc. But, I believe, it was for an air model.

I doubt anyone now would be able to market a kit for a brushless speed control at a decent price-much to complex. Don
