"ROAR-approved" has been the rule since LiPos were first allowed in the class 2+ years ago...not a new rule by any stretch.

Why is this important? Many grass-roots clubs depend on ROAR for insurance, and LiPos are definitely a safety issue. IF there was to be a fire, and IF it were shown that it was a non ROAR-approved pack that was the culprit (for whatever reason) then that coverage would be compromised. Does that mean non ROAR-approved packs are defective or less quality than those that are approved? Not at all. They might be, they might not be. But IF there was to be a problem here, none of us in our local race program can write a check (even collectively) to re-build the Shrine Auditorium if we were to burn it down. And we're not terribly dis-similar to a lot of other clubs across the country.

Even a less extreme example. Suppose that LiPo were to catch fire and get dropped onto the floor? Even if it didn't start an all-consuming blaze, our 2-day event each year is held on a wood basketball court. The expense to repair damage to that floor would very likely bankrupt our club or any other.

And yes we will rule the class into extinction. Sorry, I am real tired of all the freedom lovers out there who cannot possibly have to obey any rules at all. Why does anyone think they need a 5600 pack to run a class where 21.5 motors pull about 1200-1800 mah out of the battery for a run? 25.5 will be even less.

And as far as roar approved, this has also been the rule since lipo was allowed. I know everybody wants to run the $20 HobbyKing packs. I'm sure most tracks just want people to run hard case batteries.

Then how about a list of approved batteries Myself and a lot of others I am sure have a budget to work around. You telling me if I show up to race and I dont have a roar approved pack I cant race?

Not often, but I have seen it done.... 2 heats without recharging. Never seen three heats though. On the packs I am seeing a lot more 5000 packs with 35c ratings for $50 or about. I am glad not to need a $120 thunderpower for this.

Look, the rule we have defined is ROAR approved. If you go to Strictly or Winthrop Harbor, and they let you run Turnigy or who ever's hard case pack, that is up to the track operator. Almost any track you go to, including Leisure, will say "ROAR rules" most of the time. I can bet 1/2 the guys racing offroad are running the cheap packs from Hong Kong which are not approved by ROAR. The problem is that once you open the door a crack, everybody tries to break the door down. I know there will be a lot of people running non approved batteries. I also don't own a track or run races, so the rules are in the end a guideline. ROAR's approval is at least a baseline of safety. If a track is comfortable with non approved packs, then more power to them. Ask your local track operator what they want to see.

OH GAWD...don't ruin anyones day by using rcgt as an example. Then again..I don't figure VTA suffered to much over the almost complete demise of rcgt.

That being said, it amazes me how many people continue to try and create strife in a succesful program that has become one of the best ENTRY classes in rc. NEW PEOPLE are getting involved for all the reasons that VTA was designed for. It may surprise all of you existing racers but YOU are the minority !!!! And don't forget that YOU choose which classes to get involved with and what equipment will suit the need. If you want to run 2 classes but the 5000 isn't to your liking....then sell your 5600's and buy all 5000's.If you're one of the 99% of us who aren't professional drivers..you're not likely to notice much of a difference. Lets face it....you probably bought 5600's because somebody told you it was the best choice.

Stop trying to mess up a great program. It's working and growing. If you don't like it, don't bash it. You've made your comments.....now move on so some NEW driver can see what a worthwhile choice VTA is.
Keep in mind one more positive note. VTA has always promoted that a club can use whatever rules they wish in everyday use. But when it comes to VTA recognised events....the national rules must be used.
IMHO, best to use the national rules or as close as possible.

VTA rules work well for a number of reasons. As a race organizer, the rules are and have always been, good at making for close racing. The new rules (the only revision), will make for even closer and now cheaper racing.

I've been told it's all about the perception, but a 20C 4000mAh battery is no match to a 45C 5000mAh. I don't see a problem with my 50C 5600mAh and neither do the places I will race at here in ND as far as I can tell so whatever. I'm not going to travel to race this class where they won't allow me to run my equiment. I'm sure when the 5600's become more of a commodity the rules will change eventually.

Generally speaking, 2 X C = max current draw in Amps
The average TA car might pull 50 Amps at start of race if the car is at a dead stop.

Honestly, get the lower mAh pack. The advantage is lower weight. Then use the weight savings to balance the chassis better. I run a 3200 in a couple of my cars and have one of the best balanced cars on the track. The 5600 is going to be heavy, throw off your CG and probably force your car out of balance. Just plain overkill. If you can pull 50 Amps out of 25.5 Novak other than initial takeoff, let me know. 25C to 30C is just about perfect for this class, 40C is overkill.

I understand that, I just want to use the 5600's because that's what I have. Good to keep in mind though, in case the class gets really competitive and I feel the need to step it up. I just want to have fun inbetween 1/12th.

Dont forget my enduro...28min on a SMC 4000 28c pack(21.5 setup)...

also dont get caught-up in big battery better crap...a good 20-30c 3200-5000 is always a better chouce....alot of times with those big batt, you never use the juice anyway....

I plan on using the Venom 3800 35C 2S lipos from my Slash Spec program for VTA. Still gathering repair parts for the cars and still need to get a body. Trying to sell some left over AR-15 stuff to finance my VTA cars. (had to quit shooting rifle competitions due to medical reasons. WILL NOT OFFER FOR SALE OR TRADE HERE AND WILL NOT ANSWER ANY AR-15 SALE RELATED IM'S OR POSTS FROM RCTECH PERIOD). They weigh 1 & 1/2 ounces less than my 30C 5000 Mah Venoms and that weight will make a big difference in balancing the car. Looks like the first one completed will be a LOSI XXX-S with either an XBR or GTB.
