The section rules in the BRCA handbook anly apply to nationals, sanctioned events and other events that want to run to them.
So some clubs and regional series run to strict BRCA rules, and some don't, you need to check with your likely racing location / class to see if they allow LiPo's or not.


the way this reads leads you to the answer if a host club allows lipo you can use them unless you are running to strict brca rules followed to the letter.

Regardless of what the matcher manages to print on the label. the cells are 1.2v cells, regardless of capacity too.

6x 1.2v = 7.2v.

I mean, this 1kg bag of sugar i bought from Tesco actually weighs 1.07kg on the scales in my kitchen, but it is still a 1kg bag of sugar.

how many volts and milliamp are the bags of sugar Chris and are they race legal lol

O can i buy a x6 shell of you or Dan if u have one for sale please

paint job not for us cheers i presume your coming to bury Sunday?

Oooh, you should see it when I try to charge it at 7amp *BANG* :D

I don't have any clear shells, you'll have to get that of esro or X-Factory, but if you want to borrow one while you get fixed up, I have the Red shell I used at the Euro's spare. It has a hole in the windscreen.

Can't do Bury tomorrow mate, sorry, got a family meal to go to, so i am off to Teesside tonight to get my 'weekly fix' of racing.

Chris

thanks for the offer Chris, its for someone else thats bought a x6 and wants it painting in his own colours, ill contact Daryl direct, thanks for the offer though , and enjoy your meal.

No Advantage in Voltage?!
1.2 is the nominal voltage (=7.2) and 7.4 is the nominal voltage of a Lipo.
They both produce more than their nominal voltage.
If you look at Trakpowers own info you will see that for yourself.

But if a host club is running a regional event then Lipos cannot be used as it is a sanctioned event. Off-road is the only section that has regional series. 1/12th doesn't, Tc doesn't but has a bunch of other series - some of which are sort of regionalised but aren't sanctioned.

You already have had the answer.
That is the same question you put on RaceChat over aweek ago.
You have had the answer.

So all you are doing is stirring.

wrong im asking a valid question to a post!

not read them, but as someone has already posted, they haven't adopted the EB as yet and will probably not have narrowed down the power source.

Really?
You should read your own cut-and-pastes!
(Try post #6 for starters).

and?

it shows sections dont have to use what the eb say, this forum is more off road and allot on here dont do rcracechat,so i wanted thier views, do you have a problem with that? if so see me on rcracechat ;-)

Come on guys, stop swinging handbags and play nicely. :D

The way I see it, this is a new question for this forum so the valid answers here add value to the forum. Doesn't matter who asked what where, the resource for anybody else searching is here too now.

and ? it shows that your reading is as suspect as your typing:rolleyes:

Simple Facts: -

• Lipos are Not allowed In British Radio Car Association sanctioned meetings and this includes Off-Road Regionals.
• Bikes do allow them, as they do not run to EB rules (don’t have four wheels either).
• All other Sections run to EB rules and can decline to run items on the approved list but can not allow the use of items not on the list.

You can run them at club level if the club allows them.

bikes are under the brca as a class !! irespective of amout of wheels
12th scale allow lipo as reciever packs, should they?
Jason for some reason you seem keen on having a dig at me take the pi55 all you want on my typing im used to my dislexia being ridiculed, im sure there is not need to get personal.
do you actually race off road?

Since when have receiver packs been regulated?:confused:
Roar have banned the use of all Lipo packs, including receiver packs.
1. I'm not Jason.:wtf:
2. Well, as you know that you have a problem with your typing then use a spelling/grammar checker!
3. Selective cut-and-pasting is something that just mis-informs people.

oh dear lack of knowledge! you simply buy a reciever pack regulater, lrp and lots of others sell them
who gives a flying frig about Roar, ill never race to those rules and who on here will this is a uk forum and UK runs under BRCA
1/ ur not slowcoach on rcracechat then?
2/ nope ill do as i do not as you say, if you dont like it simple solution is X on top right!
3/so is lack of knowledge ( see top sentance)

I'll start the scoring.

1-0 to Mark so far. But can Slowcoach equalise? :confused:

im not wanting to score points or argue but for some reason he seems hell bent on having a go at me?

you seen to have that effect on people mark:D

Hi Mark,
I know, and its ridiculous. Your points sound valid and his defense/attack won't stand up to it so he goes to personal attack. His every post devalues the usefulness of this thread to any newcomer looking for informed advice.

Have you upset this guy on another forum?

Can't we all just love each other? :)

In the end, this is an emotive as well as a motive subject. there are pro's to running LiPo and there are VERy BIG cons right at the moment with LiPo.

Until some form of regulation comes into place from the BRCA or EFRA or IFMAR, whats the point in arguing the toss. They have till the end of this year to devise a construction ruling for LiPo, as cells HAVE to be homologated once a year.

Before LiPo is allowed, then stuff that is for sale over the counter, should have a balancer and a voltage cut-off built in. Solid case design for impact protection, and a minimum current rating on the gel cell inside.

Till then, if a club allows LiPo, I could legitimately go and buy a 10C lipo gel pack, in a silver packet, use it without any voltage protection and blow it up on the track, let alone the fact that a lot of people who WILL buy these, won't have the correct charger either (and Mark, it does and has happened quite a few times). I know the BMFA has instigated some safety rulings for clubs now, they have to have a bucket of saline solution (salty water) to diffuse packs.

In the end, you two can argue the toss and swing handbags, but until construction rules are made, clubs shouldn't touch them, they have a responsibility to their members and members safety (and yes, I do know that Sub C's can go pop). And your BRCA insurance won't cover you for a pack fizzing on to you in the pits, only inside the track.

dont you start LOL
probably

yes group hug! :D ;)

Ok, before this turns into a full handbags at 50 paces thread...............,

Whilst doing some background work for the recent oOple lipo review, I produced some discharge graphs. For interest I did an overlay of the ib4200 shv pack (blue line) against the lipo (red line). Both packs had had a similar number of charges from new, and this is at 20 A discharge.
Results are not what I expected, although what you cant see from this graph is the available "punch", which I suspect will be quite different owing to the internal resistance differences between each type of cell composition.

personally dont agree with balancer or cut off as
1/ many speedos now have it
2/ one balancer for £25 will do all your cells so whay have one for every pack individually, plus how would you make it work? a charge plug and a dis charge plug? thats asking for more trouble,
the main thing here as with anything is educating the end user!

Mark, I have countless ESC's, onlt one, at the moment, is LiPo ready, and then it don't autodetec the cell count, so you still have a fundamental issue in that you MUST select the cut-off point, I don't know anyone localy who has a LiPo cell enabled ESC, the newest of the new are LiPo enabled. But those who want the cells (club racers) tend to be at the bottom of the ESC pool, usualy running second hand ESC's.

As much as education is the correct phrase, you have to look at it from another point of veiw, there are a lot of people out there who turn up at meetings, and no matter how much you educate them, they still do it wrong. You then throw in a LiPo cell, which HAS to have a LiPo profiled charger and either a voltage cut-off or lipo enabled ESC that HAS to be set correctly, your just asking for trouble.

Not trying to aruge the toss or create ill feeling and do see where you are coming from. But I am a great beleiver in Murphys first law of idiocy, if it can be done wrong, you will always find someone who CAN do it wrong.

Those same people probably drove to the meeting - a far more dangerous activity. You can't stop me from driving to work because some numpty crashed once. If you are going to use things improperly in any respect then you're asking for trouble.

You really need the proper equipment yep. I used three ESC's with the LiPo and none had protection, but I knew not to run the cells flat. Everyone who buys a LiPo would know that since it tells you clearly. Whether they act on that adivce or not is up to them. :eh?:

I agree, but then it is also up to the clubs/series organisers/governing body to sort out regulations. I am not against them, it is just, at the moment, way to many possibilities that do make me a little nervous about them.

When a correct charger/ESC/LiPo are used, fine, but unlike any other change in RC Carsover the last 15-20 years, none has needed you to run out and NEED to get new stuff to use it safely.

dcm if you cover postage each way ill send you a trakpower pack and charger to use for a month!

What is the purpose of this thread?

Looking at the title it is about the legality of Lipo and insurance.

We know that using Lipo has no effect on BRCA insurance.

We know that Lipo is NOT legal at BRCA Sanctioned events (In sections that have adopted EB rules), this means Regionals, Nationals and EoE Finals for 1/10th Off-Road.

Is it time to close this thread so the facts don't get clouded again. Open a new thread for the benefits of Lipo, how to use them, etc

once again tom seems to be the voice of reason and sense, why is it that a teenager seems to bring a valid point, and you guys cant,without fisty cuffs
come on guys take a chill pill
group hug
next thread

I only offer the 'other side' of the argument, but not in a LiPo is evil sort of way.

I have three LiPo enabled chargers but only one ESC (18th scale) so will decline the kind offer (again) Mark.

can send a voltage cut off too, but use yoor common sense and dont run them flat!

that was why i started the thread!

So let this thread die its death as its purpose has been served, and not post incorrect information as facts.
