Best post yet!!!!

So why mandate 4 or 5 cells in TC when one can simply select a milder motor to run slower, reduce current, and extend motor and brush life?

me thinks that be bad idea
this will surely put the mockers on off road

that WC guy only use 5 cell ONCE ,it was really slippery end off & he had the bottle to try & do it
But he still uses 6 cell by far ,Also off road 1/10th would even more slower then it is now

BUT
you can`t have 4 cell one country then 5 cell another then 6 cell another
this brings manufacture`s into play to which market gets there attention , which market gets stiched up ,which market gets left behind

Disclaimer
Don`t start splitting hairs just to pick holes in my post`s
just thought`s only (5 cell it will be ,but i`m allowed to gripe about it

thank god they not in control of politics be going round in circles

it `s only gone 5 pages & we got Rick to sort the problem out allready
you should of gone to the EFRA meeting instead

I would like to eliminate motor class rules and use the number of cells to determine your class. 4-cell=stock, 5-cell=19, and 6-cell=modified.

Wrong answer - we definitely don't want 4 cell in stock.

better answer

6 cell stock
5 cell 19t
4 cell mod.

cheers

while Ricks idea is pretty innovative, how will it affect people that run multiple classes.... Cannot run the same battery in stock and 19t anymore.... or 19t and mod...

We both live in the real world and where there is a relative abundance of grip people will not, have not and do not arbitarily limit themselves. Thats why we have motor classes to create a "level" playing field - thats why we have weight limits, rules on wings, bodyshells and tyres. So cars are relatively the same speed. Would you select a milder motor? Of course not. Would you run a more realistic gear ratio in 19T to preserve the brushes and comm? - I know I wouldnt....

What I'm really interesting is. How the hell you can get 5cells 1350g? If anyone every did that, post photos PLEASE.

The lightest 6cells I can made is around 1470~1480g. Lost 1 cells it's still over 1400g. 1350g... someone please post his 1350g 5cells car photo (don't tell me use 3000- battery, no one do that nowday alright?)
I have 60g of lead on my MSX to make it 1500g, add 70g to that for one less 4200 cell that's 130g to deduce from 1500g, which is 1370g, pretty close IMHO.

No offence but you know this isn't happening. If I remember well your car went thermo while you were leading one of the finals at the WC so even you didn't do that, and you can bet that if a driver can handle the power of a 6T he will use it even running the risk of blowing it up.

6 cell stock
5 cell 19t
4 cell mod.

cheers
what's the point of that ? making all 3 classes closer in speed than they are now, so what would be the point in having classes at all ?

The point is that stock is fine as it is - 6 cell and doesn't need fixing. In my opinion 19t is fine as it is and doesn't need fixing either.

The perceived problem is in mod and moves are being made to fix that - doesn't mean they have to slow down teh other classes as well.

I was simply pointing out that I thought Ricks solution was wrong.

Exactly. I could blame the ESC, my motor, the rules, high voltage batteries blah blah blah when I know full well the reason my car shut down is because I was driving it poorly and did not compensate for main day conditions. It was MY fault. Although I admit it would be a lot more convenient for blame something other than myself.

Hmm. In a way, I have felt that the mod rules have stayed quite stable for a while, and although getting faster all the time, it's getting a bit easier to understand...

Cars look quite alike, brushless is the way to go, and batteries are getting better in terms of a longer lifespan without beeing complete garbage...
The cars are getting silly fast, but that means that everyone will need to restrict themselves, and everyone will have a better shot at it, sponsored or not, power is insane. In 2wd offroad, that has been the case on several tracks, and that class is most definitely alive and on a roll upwards again. Simply because when you have too much power, and need less, expenses aren't very big... The other way around is bloody expensive.

I can understand any factory not wanting the expenses to go down too much though, 'cause no matter how cheap and even we want the racing too be, they need to sell their products to live...
