Dawn thank you for your efforts! Then I guess what we need is to have ROAR call a meeting to make all the rules about Lipo. We need you to start talking and offically asking for the info you need from manufacturers and racers and begin the comunication process ASAP. Its the only way things are going to get done. What information do you need? What will the meetings cover? What are the specs or requirements Lipo will need to meet?
I'm sure Rick Howart and Tim Potter, Danny SMC, Orion and the rest will be more than happy to meet and discuss all matters and get this resolved ASAP.
When's the first meeting?

Guys I don't think you realize what is going to happen when lipos become race legal. nimh cells are going to disapear & it will help to increase the popularity of the hobby. You are going to start to see long 20 minute mains instead of triple mains, you will start to see more afordable race budgets, and quite honeslty I think everyone should run in the same class per chasis class, perhaps w/ a pro & sportsman like you see w/ the 1/8th scale buggies and 2wd nitro. Imagine if world class driver's battery, esc, & motor costs for 2 years of racing in one class set him back less then $500. I see people go through more then that in a race weekend. This is the direction electric is headed in, the only variation from class to class will be the chasis. If roar doesn't want to lead the way for classes such as this then you will see local tracks & clubs lead the way as many are already doing.

We can suggest things like 7.4V max, hard case, plugs for easy disconnect in case of a failure, some safety standard, etc.
The question is why would it be a free for all? Chassis designs, weight, and weight distributiion would limit what you can practically do. Batteries are the biggest problem now with NiMH. When it is not battery failures, it is legalization, new cells, inconsistent rules, etc. Opening it up to any 7.4V LiPo battery (assuming other rules are met) would avoid the problems we have faced with NiMH.
I wouldn't mind opening it up even further, like what was done with the 20-minute LiPo truck class at the nats...LiPo - BL - 20 minutes - make it happen.

The Lipo/BL event at the off road electric nats was awesome....
Lets get this done..!! 7.4V max, hard case, plugs for easy disconnect in case of a failure, some safety standard, etc.
This can't be that hard.. is it?

ROAR works.
It is nice to see people engaged in a productive conversation. Like ROAR or not, we believe they are going in the right direction. It may take some prodding by its members to get things to move at a faster pace but we do feel it will get there. Stay positive and don’t be afraid to email your ROAR representative and tell them what YOU want. They work for you. We will be having more discussion about ROAR in the very near future. Thanks for watching. Jeff www.rctvlive.com

I believe the manufcturers will only build chassis to take advantage of the as much battery is required ot run a race. In the case of TC now, it is 4200mAH, which is a LiPo size that will fit in most cars. Amking room or a chassis for bigger batteries is pointless. They may do it, but who is going to buy a racing chassis that can hold a 10000 mAH battery? Especially if you do a rule that limits chassis weight minus the battery.
Another thing with LiPo is that most development is with the C rating. So as batteries get better, they do not get bigger.
My opinion is that chassis manufacturers will limit the size of the batteries in their designs. This is my theory:-)

this is nice... productive conversation without one name being called... LOL
Jeff - thank you to you and Mike for your show on 11/5!! And yes, lets get together to work out a Q&A session so the membership gets to ask what they need to and hopefully we can give an intelligent answer. (I'm shy with public speaking though.. so I think I'll have our promotions director contact you! LOL)

Also suggest charging rules that absolutely ban any charger or charging practice that gets the voltage of LiPo cells over 4.2/cell. It will yield more voltage, which is what racers will try to get, but will also lead to many catastrophic failures. Whatever you do going forward, please do not ignore this. There should be a penalty, like a ban from the organization if you're caught breaking this rule.
It can be enforced/teched with a voltmeter. A 2 cell battery should NEVER be over 8.4v after it comes off the charger.

I hope that something like this can be enforced practically. What was done at the offroad race?

All the documentations ive read does not show performance gains by abusing the charge settings.
Rick, Dawn. A separate trial/exibition class sound like it will be the best idea for the mean time just like the last off road nats. Participation in this class will give a good indication or interest for lipo/bl racing.

You cant really do that w/ lipo...they work diffrently than nimh...and most chargers dont allow to charge lipo at over a 2C rate, which is the most than they can be charged at at this time, safely...also the 2c charge rate will not give someone a faster run, either, I dont think...

So who's looking at the effect of implementation of LiPo in 1/12? Sedans are easy...7.2v-7.4v who cares? The challenge in 1/12 is that the voltage used is almost exactly half-way between the steps allowed by 3.7v cells.
I've seen a few people playing around the fringes of this but haven't seen a truly workable solution that is easily enforceable. The closest I've seen to "workable" was this past weekend in Denver a fellow was running a regulator on a 2-cell LiPo. The challenge is how to enforce regulator settings, etc.
Exciting times.
