even with the brushed motors how many novak esc's did we go thru, don't remember all the names, but my first was a cyclone with a purple label, then you had to get the green label, then the green label with the TC on it, not to mention the other manufactors esc's, oh and lets not get on the brushes, and secrect soaking mixtures and the differenct springs with a special little kink in it. on and on..... stock was never stock.
