Thanks:thumbsup::thumbsup::thumbsup:

I use 4mm bullet and plug right into the battery (Track Power). Is this legal in mod ?

Thanks, Bill

Yes that is fine. Just can not be hardwired between battery and esc. Must be unpluggable at some point

Rob,

I understand why you want to have the connectors to the esc and it makes sense. Might I make a suggestion to save cars, bodies and equipment. Require a connector on the esc wires and then the negative wire from the batt goes directly to the esc connector. Now the positive wire goes to a female deans connector at the rear of the car, then the positive wire goes from the other side of the connector to the esc connector. Then using a 4" peice of wire you make a loop on a male deans connector to be plugged into the connector at the rear of the car. This is the emergency diconnect system required for drag racing in case of a runaway or even worse an electrical fire. No need to destroy bodies or risk burning fingers, just yank the loop and power is cut off. All that is needed to secure the connector at the rear of the car is a tie wrap placed properly.

This may be overkill, and everyone would whine about it, but to be honest I would do it in a heartbeat to save some burns and a destroyed car. I mean what would it cost? 4$?

[Mason]

rj, i think the idea is to be able to get the battery out of the car so you actually save something with out dumping buckets of sand or whatever onto the car and in everything.

Rob I understand that these are all safety issues. But in my area we have been running lipos for around 3.5 years now. We have had no situations with these batteries what so ever. So my post is to figure out why all of us are being mandated with so many rules? Honestly if a person can not read the charging directions and follow them, maybe they need to pit all by themselves away from others. Mandate that all batteries are to be charged at the correct c, and i will bet there will be no problems. Abusive charging is the reason for all of the failures (fire) with lipos. Which is the case with all of the sub c cells exploding. I guess I don't see the point for rules like this. To protect those that are stretching the rules to the point of breaking! On their behalf thank you for looking out for them.

[Allan Webster]

Is there a version of the rulebook updated with all the new information, or some of the new information?

thanks

I cant speak for lipos yet but the reason for all the nimh sub C packs blowing if equalized and charged properly was a MFG of battery problem. It started with 4200 nimh came out. If you used a very good charger like an ice, that would be smart enough to see the voltage drop during charge when a cell went bad, it would shut off 90% of the time before the cells exploded. Using a charger like the older tekin that does not care how many cells its trying to charge would blow the pack every tine when a cell went bad during charge. I worked closely with a few matchers on the problem. They all dumped the MFG in china soon after.

I am ver pleased that DODC rules are lipos and as far as I can tell so far, when charged properly using a balancer, they are very reliable and safe. They also have a rule that will stop the abusive charging, here it is from rulebook

All racers shall take every precaution to insure safe charging and discharging techniques with their batteries. This shall include but is not limited to, attentive monitoring of battery during charging and use of a proper charging container i.e., LiPo sack. To insure safe charging methods are followed by all competitors, all batteries will be checked prior to each race to ensure battery voltage is a maximum of 8.44 volts or less. If the battery reads 8.45 or more you do not race. Battery temperature may also be checked with the following pre-race procedure. A control pack will be placed in the tech area for the purpose of monitoring the pack temperature. Checked batteries shall be nor more than 70° F or 10° F above the temp of the control pack whichever is greater. All DirtOval.com Spec batteries must use the supplied deans style connector.

I did not know they were doin battery temps. And my point was why do so many have to be told no to do something? Just for a few that want to push the limits!:tombstone:

Because just a FEW push the limits! You have to check everyone to find the few.

Actually we are not telling the ones who wont do it not to. We are only telling the ones who would that they now cant. If you were not doing it before than no one is telling you that you have to stop doing it now! Whats the problem?

It is more than a safety issue with some of these aspects. There are techniques that can be used with these batteries that can enhance the performance of them but are not very safe in the way they are done. We are simply trying to keep those who push the envelope from doing so in order that others wont feel like they have to do it to keep up.

How do you enforce a rule that says all batteries must be charged at the correct C rating?

spec chargers

[AscotConversion]

There was already a thread on rctech.net last year that detailed a way to overcharge lipos which if done incorrectly, results in a fire. This was figured out by some carpet oval guys like last year. The point is there are racers out there now who are already abusing the packs in a dangerous way, so these rules are needed to keep a lid on things.

[tittytat]

It is just hard to believe that some would put themselves and others in harms way for such a little advantage. Thus having to make such rules to get them to understand. Was not arguing the rule, just thought we as racers and humans would understand the great risk. That's all. That's why i stated thanx for looking out for those who can't for themselves.

some people have to win more than others. and some will do whatever it takes, regardless of the risk. just ask Jerry Eckman and Bill Orndorf. These 2 braniacs decided it was a wise idea to put a nitrous bottle inside of a dry sump oil tank. That is until it exploded one day in the pits while the car was on jackstands. The bottle landed 2 pits over. imagine if that bottle had hit a kid walking innocently through the pits with his parents. Too many people don't look at the big picture.

I used to build battlebots....if you guys think these rules about battery safety are a lot, try building bots.....Tech inspection for a battlebots TV tournament took 4 days!:yellowflag::yellowflag:

I have been wondering about this for weeks now but just have not asked the question, say for some reason your motor is torn down in tech and after the motor is deemed legal and rebuilt is that motor still considered a limited or a mod motor hope I explained good enough.

Hope that made sense.

KevinMakes sense to me was'nt sure, so I'm guessing you can replace the piston and sleeve also.

[Rob Cutman]

The rules page has been updated with all of the revisions liste here.

ALSO:
Sprint car wings can be made of lexan, carbon or aluminum per the new rule revisions. That is one that was not listed here earlier.

ALSO:
Tire & wheel widths have been corrected.

Thanks,
Rob

hey rj14 my harley ridin buddy Jerry Eckman had nothing to do with that it was all bill and he just had to beat glidden and morgan and really wanted tq at home track andalso at that time bill was desperate cause glidden and alderman was winning everything god forbid if it happened but if you go the races when you buy pit pass you sign a release waiver cause guess what racing is dangerous!!!!!!!!!!!!!!!!!!:mad:MY FREIND JERRY HAD TO SPEND COUPLE OF DAYS IN JAIL FOR SMACKING BILL AROUND A LITTLE BIT!!!!DANG ANY WAY yall have got to be dumb to charge those lipos any higher than recommended charge rate and put them in a one of thoselipo bags rj14 you got me so mad dude im shakin and can barely type and my wife just read that and is p-d off and said he dont cheat at racing just women man has to many the better the tchnology the more dangerous it took me 6 months before i bought a lipo cause of everybody talking bad about them and how danger with them so i just charge them at specs NITRO STILL RULES!!!!!!!also when i was at street car nats at norwalk a guy from ny had a bad a- - dodge dart pro streeter and was in staging lanes hit button to start-up and boom part of intake implanted in a womans head so racing is dangerous legal or illegal! something went wrong nos system but legal in the class he was running we was standing 20 feet or less from that car

[JASONHastings]

Tech should be real interesting the first of next week.

[rj14]

Jaybird, I used to work for MSD. I sat in the bar at the Holiday Inn at Rockingham with Jerry drinking one night. I have nothing against him personally. He knew what was going on, regardless if he had anything to do with it or not. As a driver ignorance is not an excuse. Same applies in this discussion. Did Jerry deserve what he got, no. Should he have been punished, yes. Bill got what he deserved.
