That being said esc vs esc you're getting into "losses." Which esc has the lowest on resistance, who runs cooler to keep that resistance down,etc. So in theory the top level esc's "may" be worth some time, possibly.

Now motor vs. motor. This is going to be all about which one can get the most watts while still being efficient. Efficiency is really only an issue with 1s applications since the races are 8 minutes and every tenth of a volt can matter.

What I don't like seeing is guys overcharging lipos, charging lipos on nimh mode to bump the voltage and a few other unsafe practices I don't care to mention. All of which I witnessed at the Offroad Nats.

Blinky mode has opened the door up again to motor of the (insert time frame), and who can get the best batteries and charge them JUST under their failure limit...No thanks.

You guy can have it. I'll race mod.

If everyone was really worried about limiting a class someone should have introduced a rev limiter device as I suggested previously, or perhaps run the entire setup in dual mode aka sensorless. Sensorless eliminates the sensors and ANY motor timing period. It physically cannot be "boosted" or modified past a certain amount of timing, period. Problem with this I suppose is that not everyone else can do this....
Agreed on all points but the very last. There was nothing wrong with boost at all. Boost gave an individual the opportunity to tune the ESC to work with different motors. You could set up a car to be fast in the infield and on the straight, all with very reasonable motor temps.

Enter blinky, MASSIVE roll-outs, high temps, and invariably more wear on electronic components. Blinky is probably easier to understand for many, but after they realize how fast they're going through equipment, they'll be just as fed up as they were with boost.

I also don't really buy into the whole "closer racing" aspect of blinky. Are there any racers out there who went from 15th at their clubtrack, to 3rd because of blinky? If so, please share your experience. But from what I've seen, the only thing that has happened is an artificial impression that the racing is closer. Because you took HP away from the fast guys, and their times suffered, at some tracks the fast guys lost a lap. The guys who were ALL for blinky, didn't go ANY faster, but now there a lap down, rather than two. Is that really closer, or are we just handicapping the guys who know what they're doing? Yes, technically the racing is closer on the clock, but not because everyone was suddenly the same speed. Slowing the fast guys down doesn't actually make the slower guys faster........

So, now that blinky is upon us, what will the new "excuse/technological nightmare" be when the detractors don't win the A-main?
