Higher voltage setups provide: cooler temps, better range, more torque too etc... So why did the ROAR impose 4S lipos?

It was the industry standard at first. Sort of like 1/10 is 2s. A lot of our team guys were on the 6s forefront due to the issues. 6s is better.

In the early days voltage = speed therefore if the limit the voltage the speed would be kept in check. However they did not under stand that the correct KV matched with the higher voltage would net the same speed.

I am all for the 6s 1400 combo. That is what I ran in my Caster and it was godd for 15 min on only 3300mah.

I have a 1400kv T8 motor in 5S with a... 2200mah lipo on the JQ

Believe me or not I can drive almost 15 minutes with it and my car weights 3kg200 RTR

I strongly believe higher voltage & less kv is better too, this 4S ROAR rule makes me crazy.
European federations are following it like blinded. Luckily I live in a small country and people establishing the brushless rules are open minded

I tested, in order of appearance:

2200kv 4S
2050kv 4S
1350kv 6S
1400kv 6S
4000kv 2S (yes I did )
1400kv 5S

And the two setups with the 1400kv motor were by faaaaaar the fastest, smoothest, coolest, most pleasant to drive combination I had.

Wake up people, everybody running 4S doesn't mean it's the best solution!

Also.. I think part of the thinking in the early days was that people already have 2s packs from 1/10. So the transition to 1/8e would be made easier and less costly.

What "they" failed to see was that, if you were to use 2x 2s, they need to be virtually identical packs. So racers had to go buy new packs anyway.

6s packs are also much harder to come by, but I guess it's the whole chicken and egg thing in this instance.

They just don't want the electrics to be WAY superior to the nitro's...

I think it comes down to being easier to control the speed of the cars. I know and understand the high voltage/low KV advantages. It is just hard to get those who are less knowledgeable to go with a "slow" low KV motor. Most don't understand.

You just know someone would show up with a 6s/2650kv setup and someone would get hurt or worse at a national level event. I don't want to think about the fall out from an accident like that with lots of press coverage.

As the 8th scale eBuggy class matures and evolves, you will see things change. You just have to roll with it for now.

Kind of been noticing a trend with ROAR. Seems like there copying NASCAR with rules and regulations right out of their page book. Seems they want everything to be as equal as possible and have driver talent win and not unfair advantage.

I sincerely hope you're not using this as an illustration of what's wrong with their regulations, right?

Also, Pulse_, have you tried running 1400kv 4S? It isn't included in your list, but if you prefer 1400kv 5S over 1400kv 6S, then perhaps 4S is even better. But then that would mean ROAR is correct...

Like what specifically?

RAOR would have a heart attack if they see my 8S set up. Was going to stick with 10S, but 8S is working for now .

I will.. I just bought an used Dnx408 that comes with two 4s lipos. Will try it out and see how it goes. I was surprised of the punch of my 5s 55c lipos coming from 6s 30c..So I can‘t wait for the 1400 4s setup

This said i‘ll test it indoor, i doubt 4S 1400 would be enough for outdoor there‘s a bottom limit to stay efficient

Do you follow the ROAR rules in your country? A lot of decisions are made to keep cost controlled.
