I think I understand where you're coming from but I just don't agree with the statement as written. Most HIGH END competition guys have battery sponsors so they don't really care one way or the other (not all, I know but MANY).

The issue here is that the average guy is going to have to run the best gear just to have a chance to win even in the lower levels - the guy who has a lipo in the B/C main is going to win (check at your track how many bad racers are running IB4200WCs now - point proven). This means that the average Joe who wants to get into racing will have to shell out $100-150 per battery just to keep up (lets say 2-3 min. for a race weekend) and this will discourage racing. I guarentee you that there will be an advantage to running some sort of Lipos over others, and instead of having prices in the $50-60 range, buying a new pack will be $150 - battery technology will still change, and everyone will be forced to update their stuff just as regularly as they do now, albeit at a higher price per technology change (again, look at your Nimh set-up, IB4200WC right?).

Another point I want to address is safety. Do you really want to be running 10+ trucks on a track with lipos in them all day long? Lets just say you get 8 heats in per day, thats 80 cycles where a lipo could be punctured, burst etc. - 160 cycles per weekend. At that rate, some batteries are bound to fail. It happens even with Nimh cells. But with a lipo, the failure is going to cause a much bigger problem. Lets say 1 lipo fails in 10,000 cycles (I'm being very generous to lipos here) - that's going to be one hell of an explosion, and we now have a racer down both a battery and a truck, not to mention a possible story on the evening news about how a kid got killed by his R/C car (you may laugh now, but it won't be funny if it happens!)

I just felt like I had to chip in my $.02 as I sell both battery technologies, and I see where you are both coming from - as I see it, with the current technology that is available, ROAR made the right decision on this.

Uh, try 1 battery for the weekend. That's all people are using now and that won't change. I actually run 2 classes on Sundays...8 total races and use the same $80 3200 mah LiPo for both classes. Others running 4200s need 2-3 for just 1 class and at $60 per pack thats...$180. My battery will last all year and they will have to replace theirs at least 1-2 times during the year...which adds up even more and we all run roughly the same lap times..PLUS I added weight so it isn't because I'm lighter. I've heard all the arguements and still don't agree because what I'm seeing is completely contrary. At the club level, .01 or .001 volts isn't that big of an advantage. Sorry to burst the bubble there but 99% of all club racers would never know the difference. There's even guys running brand new 3300mah stick packs that are running better then some running 4200mah fancy weld your owns. Why? Not because of better batteries. It's really the same arguement for everything...everyone thinks they need and XRay or Corally chassis but still get beat by Tamiya TA05s. At the club level, 90% is driving...the rest is EVERYTHING else, not just batteries.

We only allow hard encased LiPo which minimize risk from impacts. They're just as safe as NiMh and we've now been using them for over a year with NO issues and there's 20+ people using them every week.

That may be true, but if they're sanctioned for use throughout ROAR, there will be a few more than 20 people running them per week - that's what worries me. For well informed users like yourself, there is a much lower risk of something going wrong, but when you start endorsing the technology among less informed people - I worry. As I said before, I sell both and run both myself, I just think that lipo in the mainstream is a bad idea.

That argument might have more legs if people weren't racing NITRO. The potential risk of a battery catching fire and a jug of nitro on a hot day exploding due to mishandling or some idiot smoking while refueling the car...hmmm. There will always be idiots misusing things and mishandling things but you can't assume that the majority aren't bright enough to use and handle it correctly.

Anyone else find it funny that a guy from "Boom Boom Batteries" is concerned with LiPo safety?

Move along.... nothing to see here.... don't look over there at those shiny LiPo's that last a year and the IR goes down the more you use them.... no..... no..... look over here at these expensive disposable batteries.....

I need sponsored drivers for my new team: One Run - Motors/Batteries/Tires

Use it once, throw it away.

Every time this crap comes up about LiPo Safety, I just tell them this: Pop open your cell phone. Then tell them to shut up. /end of argument

just finished a indoor race series over her ein UK called BIWS sponsered by Mirage importers for xray,HB,orion etc
thye allowed orion Li-Po`s in for mod & 19t class ,there was not one issue with racers using them over the winter

But they had no probs racing them & having little Mushroom clouds popping uo all over the track
