It just makes it the best of the model. Not necessarily the best motor, but it maybe. Experienced racers know the deal. The issue is really only at club levels. A bigger issue is when a club guy ventures out into the big event world with something that isn't to the "T" legal and gets burned in tech. That is why at our track we teach that to the racers. We have a core of about 20 racers and over a dozen attended the Indoor Champs. For some it was their first big event. Not a one had a issue as they had been schooled in what to expect, what to bring and what not to bring. We also host some bigger events at our Track like the Halloween Classic. Those races get full motor tech and if a esc is questionable we can tech it also. It is a pia but race integrity is important. Club days we teach.
