What am I missing here... Why not let the racer desided, allow 4 cell, 5 cell and 6 cell run at the same time... at the different weights... you pick...

What I'm I missing?

TC racing CAN NOT be fixed by juggling cell #s. The only way to fix this is motor wind limits and gear limits...........
Yep, I agree.

Another idea :

5 minutes Qualifying : use your hottest motor to get the fastest lap

8 minutes Final : use your brain to calculate speed vs reliability

Sounds reasonable.

You want more power go for six

You want more reliability go for five

No 4 cells ( they suxs.... need additional Rx battery, and ultra matched cells ---> expensive and battery wars ).

Who cares if someone runs 4 cells, if they think it is right for them so be it...

Look at the end of the day most are going to run 6 cells at the higher weight, but ok, if you think you have got something with 5 cells, then run them....

Can you now see sharing setups?....

I was kidding about 4 cells. Of course....., if anyone wants to use 4 cells strategy are welcome.

2007 will be interesting year if ROAR allows 4,5,6 cells as part of racer strategy.

It's already "legal" to run 5 or 4 cell in a ROAR 6 cell class. Just need to meet weight.

Rick Hohwart already posted that he notices almost no difference in a car that's an ounce or so different, heavy or light.

DING DING DING... WINNER!!!!!!!!!!!!!!!

But at our club race we do not tech for weight so it's a non issue..
BUT we are going to have a 4 cell class so it's going to be interesting....

Going to 4 cell in touring car does not mean burnt out speedos or motors. The reduction in voltage would be better for these parts. The concensus from those who have tried it is it's harder on the batteries.

Maybe it's me, but since ROAR has decided not to go to 4 cell, isn't any further discussion pointless?

...we're on a thread to nowhere...

They are still looking at it as a possibility in the future. They just wanted to do some testing and come up with some actual results as well as see how things go in Japan and Europe. I actually commend them for not knee-jerking and researching things before they decide which way to go.

4-cells won't necessarily mean burnt out speedos or motors just like 6-cell doesn't either. You burn those things out by pushing them to hard when you push the gearing to the edge. The only people burning out motors and speedos now are a FEW Mod racers.

The whole point of racing is to go as fast as possible. If you're not going to push yourself all the way, why bother?

At my local track (South Shore Hobby, Long Island, NY) guys are burning out 19 turn motors at a pretty good pace. At a race last month I marshalled the 19 turn A. At the end I picked up the cars that came in 1st and 2nd. Both motors had that burnt smell that means time for a new motor. It's not just a handful of mod racers. We're approaching the point where all motors will be affected.

4 cell would have fixed this. Although top speed will be close, the amount of torque coming out of a turn would be greatly reduced, and that's what overheats motors. The problem is 4 cell would put more stress on the batteries, and that would be more expensive.

The arguments posted are mostly about equipment and manufacturers but I would suggest slowing things down to have close racing. Of course I realize that the words "slowing down" send most if not all racers into a tailspin. Most racers would benefit from having more time to react. Speed is cool but to me not as cool as good battles and side by side racing. I get a total rush from tight racing. Much more than destroying the field or having the fastest car.

Just a thought.
In concept, the idea doesn't sound bad, but there always will be guys who will just react to the equipment and end up in the same place. If you slow down the cars, they will find ways to go fast again. The class definitions will be the only things that will change, the racing will stay the same. At a local level, you've probably noticed that stock has gotten pretty fast, but those same guys will still continue to race in a class where they are matched against their same speed racing buddies. If stock goes slower, they will just turn 19t in to the new stock. Guys will race the speed they are comfortable with, not what motor is in the car or batteries. You've probably noticed this in Onroad stuff in Utah. Guys could care less what ROAR, IFMAR, the big races have for standards, they want to go fast and race a class that all their buddies are racing. At a higher level, the racing is already close; at the Worlds the top few heats were separated by only a few seconds. JMRCA tried it and they were probably separated by about the same margins, only they did everything they could to push the equipment to find the difference in speed. Yeah 6 cell at that level is hard on equipment, but 4 cell has it's problems too. Right now if you go to any big race, stock is only a few tenths behind 19t and 19t the same behind mod. The speed is dictated by the layout and the driving since most of the time laying the power down of a mod motor is the challenge. I was laughing when I saw Hara using 4 chargers to charge each cell of his pack. Bottom line is, you'll race in a class you feel is comfortable. Motors won't dictate speed, racers will.
