BRCA LiPo and Brushless lists

[ballsie]

Have these been issued yet?

I can't check the BRCA website as I only have internet access at work and work block the BRCA site.

Need to find out before I spend my hard earned cash!!!

this is all i could find on there site bud

there is a novak 13.5 on there already

[Garrypd160]

Not yet Ballsie, but I hear they are expected anytime.

[ballsie]

Cheers lads.

Can someone download them and post them on here when released please?

I can't even click the above link to access the document without it being blocked.

[big si]

ballsie without interweb access?????????

you need to get your new flat sorted bud :lol:

[ballsie]

BT line takes one month to activate - shocking!

Then there's about 10 days wait for Broadband to go live.

I'm dying without Sky TV though! :(

[big si]

oooo nasty council tv only thats not good

[Garrypd160]

Pity hes looking for the new 10.5 list :razz::-?

[big si]

:lol:

[Maxxed_Ross]

think I'll wait until I see these in action before ordering anything.

Anyone planning on running brushless from the start of the season?

[ballsie]

I'll be running brushless from day one as soon as the lists are published, my card will be taking a hit!

[Garrypd160]

I'll be running Lipo as soon as the list comes out, but wont be running brushless til this time next year I expect.

[Dave]

I'll be running 10.5 if i can find it from the start.

[Maxxed_Ross]

it'll be interesting to see the differences then!

[KC]

I will be running Brushless & lipo on fri to try it out.

[Maxxed_Ross]

how underweight does it end up running both?

[Garrypd160]

Depends which lipo you run, but brushless motors are 5g heavier and the speedos are usually slightly heavier too.

The orion carbon 3200 lipo is 200g lighter than a set of 4200s

[Maxxed_Ross]

that's a fair bit. Finding space for all that ballast is going to be tricky

[big si]

nah just put it all on the cells.

thats where the weight has gone from anyway

[KC]

I had to make up 200g on my TC5.
Its not that easy squeezing it all in.
This picture shows a lipo tray which the battery sits in. Its made of steel and weighs around 150g (thats not my car by the way)
http://i7.photobucket.com/albums/y299/KennyClark/foto_inverno200620003.jpg
Im sure these will become available to the masses pretty soon.

[Garrypd160]

nah just put it all on the cells.

thats where the weight has gone from anyway


With lead weights, theres not enough room on top, without piling it fairly high. I ended up taking mine apart and fitting weight inside, and some on the underside in the cell slots. BUt even with as much as i cld get on the cell itself, i still needed 55g down the centre of the chassis.

Tungsten weights do help, but they're not cheap

[Big Gordy]

What we need is a lead undertray;-)

[Maxxed_Ross]

http://i7.photobucket.com/albums/y299/KennyClark/foto_inverno200620003.jpg

now that is a good idea!

[big si]

i have just looked on the schumacher website at the speed passion BL motors. in the description for the 19 and 27t style brushless they say BRCA.

could this be one of the ones on the new list?????????

[Garrypd160]

The list is to be announced 2mrw. And from what I've heard, yes, Speed passion will be on it. Also Nosram Dragon. LRP Eraser and Novak EX systems.

[ballsie]

Nosram Dragon for me I think.

Cheers Garry.

[big si]

The list is to be announced 2mrw.


is it just the brushless list or the lipo one too???

[Garrypd160]

is it just the brushless list or the lipo one too???

I'm not sure. Will see if I can find out today.

[big si]

good man

[big si]

any news on this yet gary

[KC]

The list is to be announced 2mrw. And from what I've heard, yes, Speed passion will be on it. Also Nosram Dragon. LRP Eraser and Novak EX systems.

I have to say the Novak EX 10.5 I ran on friday was excellent.
Well impressed with it.

[raymondkerr]

Will you beable to run brushless at this year's Indoor GP? I was going to buy a new 19turn for the event, but would rather buy a 10.5 brushless if we are allow to run them.

Also, are the cheaper "sport" brushless like the Eraser, Dragon, Speed Passion as good as Novak's SS 10.5 or the new EX 10.5 ? I have heard of lots of people complain about "cogging" on the less expensive brushless stock motors ?

Cheers
Raymond.

[raymondkerr]

just read the entry form "brushed motors" only. :-( but can anyone shed any light on the differences between the sport motors and the Novak 10.5 SS & EX ?

Raymond

[KC]

The Novak EX is a sport motor like the Eraser etc.

[Maxxed_Ross]

I have to say the Novak EX 10.5 I ran on friday was excellent.
Well impressed with it.

you think? It didn't look nearly as quick as I was expecting it to be.... either that or I'm getting better :-P

[KC]

Bearing in mind it was the first time running it.
I changed gearing 3 times. By round 3 and the final it was geared as it should be.
Good enough for TQ so it cant be that slow.
Compared to a brushed 19t motor it felt very similar with perhaps a bit more top end.

[John Lindsay]

I'd agree with Kenny ( we had a bit of "too close" racing in the final)

I seemed to be able to make up time on the infield to kenny, and he could pull away on the straight a bit. Not a lot in it, and I wasn't really impressed with the way that axiom was running for me. I'd like to try some sort of C2 but I'm out of them at the moment.


Cheers


John

[Maxxed_Ross]

suppose you're right Kenny, it'll probably take a few runs to get it running right for your driving style

Like I said earlier it'll be interesting to see how the racing pans out if the top guys stay mixed between the two types

[hainingb]

An update on the BRCA list for 10.5 & Lipo:

I was unable to go down to a on-road meeting on the 5th Jan due to weather but they had a very long meeting and the outcome on the pro-stock class we are all looking for is a way off yet. The EB has just put out invitations to manufactures to submit equipment which in turn will have to be checked so I think it's going to be a few weeks yet and indeed could be nip and tuck for our first on-road race @ SDRCC 09-03-08. I'm sure it will be out for our first SRCA round but we may not get much chance to practice.

In the mean time I have been told it's likly to be £50 for the motor & £80 for the Lipo which must be in a hard case and just now I believe the only motors available within that price limit have bonded rotors and are sealed (none rebuildable) :erm:.

I'll keep you posted on any more info.

Regards, George Haining

[ballsie]

Thanks George,

That seems to firmly put the speed passion in the frame as it's slightly more expensive than the previous suggested limit of £40.

I wonder if the Orion hard case lipos will now be allowed as they'd fall under that price range. They don't have those deans connections though that seemed to be important before.

Cheers.

[big si]

it appears that the brca are being a bit slow at sorting this out.

if they have just sent for manufacturer details there not helping us very much

[Dave]

Bear in mind this is for the brca nationals they have plenty of time but they are not really thinking about the clubs that have adopted this aswell.

[KC]

Its also worth noting that all cells are also under review as a result of all the exploding packs of recent times.
If the the BRCA deems a certain brand unsafe for use then it will not be permitted at BRCA sanctioned events.
It may be the case that Intellect and/or East Power cells will be banned.

[ballsie]

I've just taken a gamble that the stuff i've bought will appear on the lists.

Nosram Dragon Brushless 10.5
Demon Power LiPo

I want to get racing again!!!

[Alex Lindsay]

Not before time Ballsie......

[big si]

Bear in mind this is for the brca nationals they have plenty of time but they are not really thinking about the clubs that have adopted this aswell.



not realy dave the brca is our motorsport governing body for all clubs so no they dont have loads of time. this should all be sorted asap but they appear to be dragging there heels. remember the brca agm was at least 2 months ago

[Maxxed_Ross]

Agreed, with most clubs getting back to racing within the next few weeks they are cutting it very very fine

[Garrypd160]

not realy dave the brca is our motorsport governing body for all clubs so no they dont have loads of time. this should all be sorted asap but they appear to be dragging there heels. remember the brca agm was at least 2 months ago

Actually, smally is right for once. The brca agm is only concerned with making rules for the nationals. They are not, and never have stopped clubs running anything they like. The rules have been finalised, pretty much as george has said. I assumed they wld have released them by now, but they must be waiting, in case some manufacturers dont want to submit there equipment.

[Dave]

:offtopic:

If you search the words "smally" and "right" it comes up with 53 posts which must mean i have been right 53 times or more. LOL

Back on topic the lists will be posted as soon as they can and I for one would not like them to rush the list and have them not count a motor that could be competitive with 19T brushed.

[Big Gordy]

If you search the words "smally" and "right" it comes up with 53 posts
Aaah but is it not the other way round? as in 'Aye right smally' ;-):mrgreen:

[Alex Lindsay]

So correct if i am wrong....

The BRCA have decided they want to have lipo's and brushless 10.5's for their National series which doesn't start until later on in the Year?

FRCC wants to follow the BRCA and allow the BRCA agreed lipo cells and brushless motors in our club championship?

So the FRCC championships start on Feb 1st - the question is if the BRCA have not released a list of approved cells and motors by then, what do we do?

There would no point in buying cells/motors that would not be allowed in other competitions (such as the SRCA round).

[Garrypd160]

i think you simply have to wait until the list is available. Booking in for the nationals starts on the 1st so surely they'll have released something before they expect people to cool in

[Dave]

We allow people to run any brushless 10.5 and lipo until the list is released but advise for example ballsie that he may not be allowed to run these if they are not on the list.

[ballsie]

I'm happy with that Smally.

I'm confident my motor will appear on the list, that's precisely why I didn't buy the Orion 10.5

Cheers.

[Dave]

Yeah the motor and lipo you have bought are looking good to be on the list alongside the Novak EX but we will only know when the list comes out.

I have a novak SS 10.5 that will def not be on the list but i will run it until the list comes out or in mod.

[Maxxed_Ross]

there's nothing to stop you running last season's gear until the lists are posted

[ballsie]

there's nothing to stop you running last season's gear until the lists are posted

There is actually - you've got 33% of my last years gear :lol:

[Smart Racing]

Simple, the club allows you to run what you have until the list comes out, if your equipment is on the list all well and good, if not then you loose any championship points gained using non homologated equipment be that motors or cells. ( this of course does not mean you can strap in your 2.5R until the list comes out )

[Dave]

Do you mean loose all points gained from now till the list comes out are lost to just beyond that?

You should be able to run any 10.5 motor at the moment with no loss of points until the list is published and you are then breaking the rules.

[big si]

yip not a bad idea.


the only problem in this is though the brca are looking at cells already on the list so my IB 4200 may well be illegal for use too

[ballsie]

It's horse sh*t if the BRCA ban the IB cells. I don't think we should be banning them as a club either - far too many people have invested their hard earned into them.

Have we ever had a problem at the club with them?

[big si]

i agree ballsie i just thought i would mention it

[niall_cochran]

yip not a bad idea.


the only problem in this is though the brca are looking at cells already on the list so my IB 4200 may well be illegal for use too

You should be fine si,

No cells will be ILLEGAL, that is completely incorrect. Cells have to be represented for the 2008 approval to comply with the new and more stringent dimensional specs.
In past years the BRCA cell list has always applied to all BRCA sanctioned events. Due to changes in the dimensional rules for cells, the new list for 2008 will only apply to NATIONAL events. Other BRCA sanctioned events are allowed to use cells from the 2007 list. There are many thousands of perfectly good cell packs in use by club members around the country, and they will still be perfectly able to use these at non NATIONAL events. Please check rule 3.1 EB rules on brca.org

[hainingb]

Niall, you are correct it will not affect us in Scotland this year (2008). I have however heard that the new EP4600 & IB4600 (same cell size as the 4200) have passed the new dimensional check but the BRCA still have to state this fact via their web sit.

On the Pro-stock issue the EB has recieved some lipo packs and BL motors which are being checked prior to being added to the approved list, hopefully the first draft will be issued shortly.

Regards, George Haining

[ballsie]

Cheers guys.

[hainingb]

Guys, The 2008 cell list has been posted :-P:arrow:

http://www.centralbooking.org/cbs/index.php

Regards, George Haining

[ballsie]

Excellent - will download this tonight.

Am I right in saying this is just the sub-c cell list (i.e. no lipo?)

Cheers.

[hainingb]

Yes Ballsie just the sub-c list the lipo and 10.5 BL motor list will follow shortly hopefully.

Regards, George

[Garrypd160]

Yes Ballsie just the sub-c list the lipo and 10.5 BL motor list will follow shortly hopefully.

Regards, George

Not from what I've been hearing. Lipo will be fine, but so far, no 10.5 motors have been submitted to the electric board. All distributors have declined, saying that with a £50 price limit, they cant supply reliable motors. The BRCA are now in talks about wether to adjust the price limit to suit

[hainingb]

That is why I said "hopefully" otherwise we will be racing 19T until the list is released unless the SRCA call an EGM and do what most other clubs have done and allow any 10.5 BL motor which maybe the way the BRCA end up going?. I have been involved in dicussions during and since the BRCA AGM in November last year regarding this topic at commitee level as area rep for Scotland but I do not want to add further speculation on this issue.

Regards, George

[Alex Lindsay]

Hi all - found this onthe BRCA Site today. Althought it does not mention types or manufacturers, it does give very useful handling instructions.

Safety Guidelines and Technical Rules for use of Lithium Polymer (LiPo) Batteries.

During the past year, the use of LiPo batteries for ‘Club’ racing has become more popular, as this type of battery technology allows competitors to cope easier with short intervals between races.

Previously, the Electric Sections within the BRCA Electric Board have not allowed the use of LiPo cells at any of their sanctioned events.

At the 1/10th. Touring Car Section AGM in Oct. 2007, this Section decided to allow LiPo cells to be used in a ‘Support Class’ at their National events for 2008. Obviously with this cell technology being new at BRCA events, there is a lot to Learn.

The BRCA Electric Board have compiled some basic guidelines regarding the safe use of LiPo cells and a set of basic rules to enable the Touring Car Section to have a degree of control on what cells are allowed at their events.

The following guidelines and rules are not a definitive copy ‘Set in Stone’ and may be subject to amendments as the Racing Season progresses and more information is gathered.

The BRCA Electric Board requires that all competitors that intend using LiPo cells study the following advice and operate strictly within the guidelines below.

A guide to safe use of Li-Po Batteries, from the British Radio Car Association.

Any rechargeable battery that is currently on the market has a risk of explosion, fire, and smoke emission if not handled properly. Despite the stories that have made the press, Lithium (Li-Po) batteries are not fundamentally unsafe, but they need to be treated with a lot more care and respect than NiCd or NiMH cells. Just because a supplier of a Li-Po battery does not label or warn of the dangers of their product does not make that product safe.

The principal risk is fire, which can result from improper charging, crash damage, or shorting the batteries, and this can be difficult to extinguish. Fire occurs due to contact between lithium and oxygen in the air. It does not need any other source of ignition or fuel to start, and burns almost explosively. A lithium battery fire is very hot (several thousand degrees) and is very good at starting additional fires that can result in loss of models, cars and other property. Homes, garages and workshops have also burned.

These warnings can be a little ‘scary’, and they should be as Li-Poly packs can be very dangerous if not handled correctly. However, please try and keep this information in perspective. Kitchen knives and chip pans can also be very dangerous if not handled properly and there will probably be more injuries caused by scalpels or super glue in eyes than batteries. The following precautions should help you enjoy using Li-Po batteries without having a major incident.

General Precautions

Only charge Li-Po batteries on a charger specifically design for Li-Po batteries. Li-Po chargers are available at varying prices, depending upon the features, for the same price as, or lower than, NiMh chargers.
Always ensure you use the correct charging voltage for the cell count. This will be 7.4v (2S) for car packs.

The maximum charge rate should be 1C, e.g. 3.2A for a 3200 mah. pack and peak voltage must not exceed 8.4v. For best charging, low charge rates should be used where possible.

Double check the charge voltage (or cell count), mah, and current before each charge.

Never leave charging Li-Po cells unattended (at any charge rate).

It is best to charge Li-Po cells in an open space on a non-flammable, non-conducting surface (such as a bare cement floor, brick or quarry tile) and away from flammable materials.

Check your charger for safety. After charging, check the battery with a digital voltmeter, the voltage for a fully charged pack should be between 8.32V to 8.45V.

Do not charge the battery inside your model, inside your car, on home furniture or wood floor/carpet, or anywhere near flammable material.
The minimum safe discharge voltage is 5.0V (2.5V per. cell) when under load, or 6.0V (3.0V) per. cell when not on load.

A number of the electronic speed controllers have a Li-Po feature built into their software; make sure that this has been enabled. Otherwise consider fitting a Li-Po cut-off device. Failing that, stop driving when the motor loses power, remove the battery from the car, and recharge it.

If using a Li-Po receiver pack then you will need to use a 6V regulator, that will supply enough current to power your radio equipment.

Use connectors that can not be short circuited, or use silicon fuel tube to protect exposed connections. Under no circumstances should the ESC wires be soldered directly to your battery.

Do not short the battery as it may catch on fire. If you accidentally short a battery, place it in open space and observe the battery for 10 minutes. It may swell up and possibly even catch on fire.

Have a dry powder fire extinguisher or a bucket of dry sand within reach in case of a fire.

Cell balancing is a way of ensuring your Li-Po will deliver the maximum performance and capacity over a prolonged period of time, although some manufacturers claim that it is not required with their batteries.

Li-Po packs are designed for operating temperatures up to 40°C and under no circumstances must they become hotter than 60°C.

You may need to add weight to your car to balance it and/or reach the minimum legal weight.

If a pack is involved in a crash or is otherwise damaged, remove the pack from the model and inspect for damage to the pack and the wiring/connections.

Lithium polymer batteries do not have a hard steel case like a NiMH battery. Instead, a special aluminium foil encloses them. Therefore, they do not vent. If the integrity of the battery is compromised, swelling will occur. If the battery is damaged and the case begins to expand, discontinue use immediately.


Rules for Lithium Polymer (LiPo) Batteries

For use in the Touring Car Pro-Stock Class Only


1. Lithium Polymer (a.k.a. Li-Poly/LiPo) battery packs must have a hard, protective case that completely envelopes the cell(s). The maximum case size is as follows: - Length: 139.0mm, Width: 47.0mm, Height: 25.0mm.

(Height excludes the mouldings on the bottom of the case that help locate the battery pack in the car).

2. The maximum retail price for the year starting 1st.Jan. 2008 is £80.00.

3. Individual cells used in the construction of the battery shall be rated at 3.7 volts nominal and the pack shall be 2 cells in series.

4. The battery pack shall have leads extending from the case for the positive and negative electrical connections using wire of adequate size to handle discharge rates acceptable to racing applications. Alternatively, the case shall have external connection points for these wires clearly marked positive and negative so the user can apply the lead wires.

5. The case must have the original suppliers label intact, stating the rated voltage and the pack capacity. Maximum capacity is 5,000 mah. The Brand name/logo shall be easily readable.

6. For 2008 there will be a rolling homologation list (as per. motors).

7. All LiPo packs must be charged with a LiPo-capable charger using the industry standard CC/CV (Constant Current/Constant Voltage) charge profile.

8. LiPo batteries may be charged to a maximum of 8.40V +/-0.04V. Overcharging is a serious safety hazard and will not be tolerated.

Please read the guide to safe use of LiPo batteries :- ‘Safe use of LiPo Batteries’ (above).





BRCA Electric Board.
23rd. Jan 2008.

I have searched the BRCA website and cannot find the List discussed in point 6 above.

unless the SRCA call an EGM and do what most other clubs have done and allow any 10.5 BL motor which maybe the way the BRCA end up going?.

Orion Vortex please! :D

If thats the case, then we can say goodbye to a lot of members who run brushed, as a 19t motor has no chance of competing with the top end brushless motors. The BRCA had the rule pretty much spot on to make it a fair comparison, and now they are talking about changing, purely because no1 has submitted any motors.

Seems like one of there worse ideas to me. People vote on the rules at the AGM for a reason, and now, basically they are going to change the rule, to suit the manufacturers. Are the manufacturers going to guarantee the more expensive motors wont suffer failures. I doubt it.

[Dave]

This is looking good for me anyway.

[ballsie]

Replied in the other thread - perhaps the committee should be looking at making a "sensible" 10.5 list too?

[Alex Lindsay]

How would the committee proceed with this? Would that be in contravention of the ruling made at the AGM (see other discussion on this forum under AGM Minutes)

One suggestion from me (having read the Racechat discussion regarding this)

Any 10.5 & 13.5 Brushless Motors with unsintered rotors which are priced below £50

[ballsie]

Exactly what I meant by "sensible."

Seems a good suggestion Alex.

[Garrypd160]

Seems sensible to me. Only thing i would say is, the rule should say 'with a uk rrp of 50 or less' just to make it clear. I wouldn't bother with the unsintered part. At the moment there are no sintered motors under that price but why limit ourselves in the future if manufacturers can get sintered motors below that price limit?

[ballsie]

Yup - should definately be said that its UK RRP.

[KC]

Apparently these motors are sintered and will have an RRP of £45.

These motors look the dogs and are getting good feedback round various forums.

[ballsie]

They look pretty cool.

[Dave]

All distributors have declined, saying that with a £50 price limit, they cant supply reliable motors. The BRCA are now in talks about wether to adjust the price limit to suit

As garry has stated this is why the brushless list is taking so long, so why would we limit our drivers to go to a less reliable motor and thus spend more per motor? No point in going to brushless if you ask me.

Any lipo and 10.5T motor allowed until a brca list is published.

My Novak EX 10.5 is better than most of my 19T brushed motors.
Zero maintenance racing.
Takes a bit of getting used to but its definitely the way forward.

[Dave]

You should be fine si,

No cells will be ILLEGAL, that is completely incorrect. Cells have to be represented for the 2008 approval to comply with the new and more stringent dimensional specs.
In past years the BRCA cell list has always applied to all BRCA sanctioned events. Due to changes in the dimensional rules for cells, the new list for 2008 will only apply to NATIONAL events. Other BRCA sanctioned events are allowed to use cells from the 2007 list. There are many thousands of perfectly good cell packs in use by club members around the country, and they will still be perfectly able to use these at non NATIONAL events. Please check rule 3.1 EB rules on brca.org

I ended up getting the Nosram Dragon 10.5 this week, it says on the label BRCA approved so hope it is.
I'll try it in my new TRF416 when I've built it, with the Nosram Evil ESC.
Just could not wait to go brushless on my TC's as on the buggies they are far better.

Not a bad deal for under £125.00 including the ESC.

Its BRCA legal for use in Modified, but its not on the new list specifically for 10.5s, as no motors are yet.
