Don't forget that current LiPo technology doesn't allow for a 6 volt pack, Brandon. Each LiPo cell is 3.7V, just like each NiMH cell is 1.2V.
It sounds like some education is needed for track owners and sanctioning bodies around the safety of LiPo cells. That seems to be the only real reason that there isn't widespread acceptance of the technology.

I like the thought of going to 5 cells, but because LiPo is such a well liked technology and is most likely going to be the pack of the future, its going to be hard to push 6 volt limits until there is an equivalent 6 volt LiPo pack.
I don't see that happening in the near future so the least we can is work together on getting BL into the spec classes and not alienate the ever-growing lipo crowd by mandating 5 cell "6v" in racing.

Don't mean to get off topic, but, I have seen a few posts that state moving the standard to 5-cell will help to save on wear and tear on the car. Can someone explain that one? If you run your car, moving parts move and wear. These same parts, at some time, will fail due to excessive wear, which usually come from long-time use or non-maintenance of the car (not cleaning bearings, rebuilding diffs, etc). So, I don't see where switching to 5-cells would save wear when this is the result of the laws of physics.
Please don't take that as a rip, its not intended that way. Just trying to explain it a little bit. From personal experience, it does save on the car. It's not going to instantly save you tons of money, but over time it will a little bit. The difference is most noticeable if you are running brushed motors, but that will soon be a mute point I think.

I have both LiPo and NiMH batteries in my box. I use both still in the 6 r/c cars I take to the track 3 times a week.
3 cars are brushless, 3 cars are brushed. 2 cars use LiPo, the rest NiMH. 1 car is mod, 4 are stock, 1 is rtr.
slowing down the cars would only help my wife, daughters, and sons that are racing currently. thats 5 people.
when I started I had trouble staying between the pipes, making the jumps, and not colliding with the other racers. so did the other novice drivers with me though. it had far less to do with speed then pure newness to the sport.
it didnt take me long to move from novice to stock, and even less time to start being competitive (sort of) in stock and getting a 4wd to run mod with. even in mod I am competitive (again, sort of) enough to place in races. I dont win, but I dont get smoked like when I first moved up.
I have spent some money on parts that have broken from crashing, sure. but I notice that I spent alot more in the novice class on a-arms and such than I do now even racing my mod.
I like running my LiPo batteries. not because they make me faster, they dont. but if I get off late from work, or have some reason that I cannot make it to the track an hour before racing starts, it doesnt matter because I charged up yesterday and my batteries held that charge and are ready to go.
and another thought just occured to me. LiPo batteries do have an advantage to the less than professional driver that NiMH do not offer. consistancy! with my NiMH I would have more trouble with control for the first 3 or 4 laps because the batteries had power than near the end of the race, right? LiPo has the same output start to end, thus making for more consistancy in lap times and less spinouts and/or crashes in the early going.
speaking of the time before I learned to drive a little better, of course.

I have no idea how easy that is to do... I just mean conceptually that would be a possible solution.

If people truly want to "save our beloved hobby", they should drop this forcing 5 cell on everyone business and work on getting BL OK'd in stock and 19T. You know there's something wrong with the beginner and intermediate classes when it's cheaper for me to use my BL set-up in mod than run either one of those classes.
The other reason that not much has been done to legalize a stock/19t brushless equivilant is that the technology hasn't matured yet. Brushless is certainly solid now, but new things such as sintered roters and more powerful speed controls keep coming out. If we legalize a 13.5 motor today, will it be equivalent to a 15 turn in 2 years?

Other then Roar not setting manufacturing rules yet for Bl in the stock/19t class,how is this a strong argument when the same thing happens with Brushed stock and 19t motors.If Roar doesn't want to look past the tip of their nose,then get ready to have alot more clubs and racers no longer affiliate with an Org or track that can't keep up with change.

I think the change is more important for stock. Stocks are too fast right now. True, you "CAN" run 5-cells in stock, it is an option, but who's going to? No one...they all want to go fast, and not for the sake of going fast, but to be competitive. If they JUST wanted to go fast, they'd be running mod. If everyone running stock was on 5 cells, and a 13.5 (ideal IMO), then they can all be competitive which is what stock guys desire right?
Then newbs could handle the power, be able to DRIVE their cars, and start off at a level of competition that won't leave them searching for a new hobby...

If it were legalized today, they would hand Novak a Monapoly on the stock class, hardly fair to LRP, Reedy, Orion, Trinity and everyone else out there. Once someone else has a 13.5 motor ready, I think it will get done.
Darn politics

Whether or not you like what ROAR is doing, they need to be around as an organizing body to standardize rules. Just think how much it would suck if every race you went to had a completely different set of rules? Yeah, certain tracks will allow certain things to suit their racers wants, and that is fine. But they still all hold true to the same base concepts. The whole point of this thread is to let ROAR and other sanctioning bodies/race directors know what we as racers want to see changed. Its not a thread to bash on the current rules, but rather to offer opinions on what we want changed as technologies progress.

Yea, but that is in a class that you can adjust the motor turn to compensate. Try that in the stock or 19T class where their is a motor limit and see how slow they are. 5 cell is slower than 6 cell. Its all about voltage.
