There isn't a lot of choice for pack voltages when using LiPos. Using the 2S lipos common in touring cars and 1/10th scale off-road cars makes carpet cars too fast for most people to drive even with the slowest motor available, the Novak 21.5. So by using 1S LiPos, they now have a selection of speeds that can accomodate entry level racers (17.5/1S) all the way to experienced drivers that want really fast cars (7.5/1S).
At my track the current record for 1S/13.5 pan cars is 90 laps in 5 minutes. or an average of 3.3 sec/lap. They are not slow by any means. They are averaging 23 MPH around an oval in a space 35ft by 60ft. Unless you have driven on carpet, you have no idea how fast these things can go when traction is essentially unlimited and you don't have to lift for the corners.
Do you have a car that can make a U-turn in the width of the typical driveway at 20+MPH? And do it 180 times in 5 minutes? 1S Lipo isn't dumb just because you do not have a car where 1S is useful.

Well, I could go into the fact you guys are racing with some of the worst designed motors on the planet... But I guess I can skip that part.
Anyways, 1s lipo is dumb when you could run 3s lipo, and a motor with 1/3 of the kv and do the same thing. Plus you could run a lighter battery with less capacity and have less anp draw and voltage drop. If the traction really is unlimited more power can be used.
I do not race, and have not raced on carpet, but I do know electric rc. I understand that you guys are stuck with roar (or whatever) rules and that you can only use certain motors. The fact you are working around this by using 1s lipos (and most likely not maxamps) that are very high quality does show that there are people with some creativity. The principle of what you are doing is a bit off, and the rules need to be changed to allow for that. Just making stuff work is not always the best way to go.
This is why I do not race. The rules can never keep up with the technology (as indicated by this 1s esc that has an advantage) so as usual the deepest pocket usually wins. I am glad to hear the smarter people are making do with a much cheaper esc (mmp) but that does not change the overall issue I have.
As long as you are having fun nothing I think really matters!!! It is just a hobby and should provide some relaxation! Please do not take my comments as anything other than my skewed beliefs, and I hope I have not insulted you in any way, as that was not my intention.
