I see nothing wrong with the way it is now. It's been established long enough to be settled in. Japan is known to do things differently. 4 cell Touring for example a few years back. No need to throw a wrench into what we have here. It works. Let's keep it going.

there was 5 cell touring years back, which was starting to gain traction, even xray spooled up for it. remember the XRAY #300010 T2 008 EU Rubber-Spec 5-Cell Ed. 1/10 Touring Car

$50 for a cap is horseshyte. The most you ever need is a 3200 or even the 1800 orca is tons. It helps a little with punch as even ultra high end lipos need time to start the reaction to draw current. The cap is instant so punching out of a corner you see an advantage.
If your running a 90c battery you will barely even notice a bigger cap in stock. But in mod it should save your batteries puffing ect.
Honestly aside from the booster business for single cell, you cant get much simpler for electric cars. No balancer needed.
As for being "competitive" its the same in any spec class. How much you want to spend is definitely an equalizer of sorts but driver is always the greatest factor. If you hit stuff, save your money til you dont.

5 cell was apart of 6 cell touring. Made the cars smoother to drive. Kinda like how some mod racers only charge their packs to 8v instead of 8.4v.

That's an interesting post... What kind of 2s are you running? The only 2s TeamOrion battery with 1600 mAh is a TX battery... :-\

I've recently been running 2S 1/12 with a 21.5T just for fun and I have to say the perceived benefits and negatives of BOTH 1S and 2S are being greatly exaggerated IMO.

That being said I couldn't imagine how slow 17.5 1S could be and why anyone wants to race that kinda boggles me.

The U.S. racers on the whole might be happy with what they are running (and fair enough too) but I know other countries (including Australia where I am from) struggle to generate sustained interest in 1/12. There are many reasons for this (perceptions that its an indoor class only, perceptions about cost etc) so I think that trying anything that might increase 1/12's appeal is worth considering and shouldn't be just dismissed with 'we don't do that here' responses.

I would run 21.5 2S in a heartbeat, and I would need to buy new batteries and ESC.

To be fully honest. What is fastest class at your track? I strongly believe it is one of the 1/12 classes. At TQ there is hardly any TC faster than 1/12 17.5 1S.
I don't see the need to change to 2S in 1/12. I can't believe that a 30$ voltage booster is scaring off potential 1/12 racers.
BTW 1/8 electric is using different speedos and 4S batteries and no one is talking about this.

I will say this. You do not necessarily need a super power capacitor to run 1/12th 2s 21.5/25.5 or whatever motor to be fast. Any high end 2s ESC will work just fine.

However, I mentioned the cost of the super power capacitor because there is a specific ESC which is in my mind on par with the super fast Tekin Gen2 ESC. Yes, the super power capacitor costs a little bit more money, but why fork out a wad of cash when you can simply buy a really cheap ESC and run a super power capacitor and be just as fast. Interestingly, the winner of last years Yatabe AOC for the 2s 21.5 class (Shota Watanabe) was running one of these cheap ESC's. He lapped the whole field!

Personally, I would never run 17.5 1s. When I race a class I want to go relatively fast for the money I put into it. 17.5 1s is ridiculously slow for the amount of money you put into it.

As I said in my post, 1/12 struggles to exist here and most clubs don't have ANY 1/12 classes. Most clubs I visit run at least 13.5T TC with mod TC at some. On at least one track I can compare actual lap times (available on MyRCM) and on that particular track 13.5T TC and 1S 10.5T 1/12 are within 0.1sec in lap time. Its not difficult to extrapolate that 1S 17.5 is going to be slower than that and I would estimate by a not insignificant margin. So yes at TQ, 1S 17.5T 1/12 might be a "fast" class but the RC world doesn't end at TQ (all due respect to TQ from whom I order most of my 1/12 stuff).

I can't believe that a lot of people refuse to race 1/12 anywhere but on carpet but the situation exists. 1/12 cars are perfectly capable of racing outdoors with a bare minimum of track prep yet the very idea causes forums such as this one to erupt into periods of near hysteria.

I will never cease to be amazed at what people will and won't spend their money on in RC, based on their perceptions

For those who are wondering what 2s 1s sized lipos are available.

https://www.rcmxstore.com/index.php?...keyword=7.4+1s

https://www.pro-s-futaba.co.jp/store...s+LiPo&x=0&y=0

All do respect to the OP's battery list, but those batteries are not being sold anymore.

So they'd be no good for open mod either since you take around 5000mAh out during a run.
Do they ever run them in a stock class equivalent to 13.5 or 10.5 blinky?

Recent race have a wide variety of category including 1 cell and 2 cell on a day. But racers may use same charger by cell setting every times. When you attend 2 category Q3F1 race, it requires seven times changes. If it forget once, what happen? Most cases will find out before explosion. But rare case is not.....
Any decent charger will not let you charge a 2s without a balance connector in, and will not let you charge a 1s with a 2s setting.
