i'm all for the blinky mode on ESC's (for starters i haven't had to fork out £150 on a speedo to keep more on the pace of the top guys) but 1 thing does concern me... Yes, timing advance is banned on ESC's, but am I right in assuming motor timing advance (on motors that can be advanced) is allowed?

If that is the case, what is the point of banning ESC timing & then allowing motor timing? Surely it would make more sense to have zero timing on 10.5 motors to even out the field, removing any advantage (& slow the cars which is the whole point of having a blinky rule) or just allow timing on 13.5 motors so they can run in with the 10.5's on the saturday. Plus surely if the motor timing is advanced, technically speaking, doesn't that motor then become a modified motor?

The difference with advancing the timing on the motor is that it is fixed, so you have that timing set for the whole lap. The boosted speedos are different in that they can be tuned to only apply timing at a given time. This made picking gear ratios and setting up speedos technically difficult, and it all became quite complicated.

Advancing the motor timing should give more torque accross the rev range, and subsequently more power. However, you'll also be getting the motor hotter at the same time so you won't be able to go mad.

Before we started getting boosted speedos, we played with the motor timing in 10.5 and found that anything more than about 10 degrees just meant the motor got too hot during the run. Also, once we'd found the best compromise, we never changed it.

Is there a bodyshell list for the nationals anywhere,

the BRCA site seems to suggest only the EFRA shells are legal (there are only about 4 on their list), yet Jim Spencer was telling me last night there are more from last years list BRCA still allowed & pretty much all the open cockpit shells have been taken off the list. Can anyone confirm this?

Cheers Glenn, however that was kind my reason for asking what this years list was as it seems there isn't one other than a suggestion that the EFRA shells are legal, so doesn't really answer my question other than knowing what the open cockpit shells are that are being removed.. I've got a brand new closed cockpit shell sitting here & another one sat in the model shop waiting for me, however it's not on the EFRA list, so the question i suppose is can i use them in the BRCA nationals or have i got to order something like a Bomb-R or the AMR12 which are on the EFRA list.

Altho i am only doing limited nationals and will be my first year in racing 1/12th it seems i have made wise choices in gear selection.

I have 2 AMR12 shells sprayed up and waiting for collection so i have nothing worry about if i do attend a national.

It seems all my question asking has payed off.

Many thanks to all who have given me advice.

EGM Update - summary of the changes

Quote:

We adopted the Global Body Standards for all 12th bodies. This is the same as the existing EFRA Rule. To ensure that we don't ambush the retailers and distributors, the current BRCA body list will run until 1 April 2012. The bodies you can now use will all be on the BRCA list until that date.

Bodyshell rules for 2011/12

what are they?

as per post 28?

Whilst I appreciate there is a bodyshell list, the reality is that there are three shells that work on the track. Most popular is the Protoform AMR12, which works well everywhere, especially in Modified. Next up is the Black Art/CRC Bomb'r. This has more steering, and is favoured by some drivers and useful in Spec class. Least popular is the Parma EE1, which tends to give more mid-corner rotation at the expense of turn in and exit speed.

Most people would choose the AMR12 for both classes. HTH :)

We have been running 10.5 blinky at the club I go to for a couple of months now, and what we find is that motors that can have the timing advanced run at around 58mmpr, whilst my original GM (with the fixed endbell) runs higher at around 62.5mmpr. There is next to no differance in the performance of the motors however the advanced timing guys motors are mega hot at the end whilst mine is not even slightly warm by the end of the run! So, it may be the case as the season progresses that people wind the timing back from the endbell and gear it up instead. Works for me at the club! Cheers.

'Blinky' esc list posted on BRCA site.

No Nosram's on it though:confused:

I've just got a Speed Passion GT EX 1S for this series and that's not on the list but the identical Hobbywing Xerun 120A-1S is.

Who is the best person to contact about this discrepancy?

Mark Stiles or SlowOne on here should be able to help or look up the 12th committee via the BRCA site

Hi Mark

Is the Tamworth meeting next weekend 10th/11th open to spectators or general public?

Entries are taken on a first come, first served basis, and are only confirmed once payment has been made.

Entry Info
All events: Saturday is Stock Class (blinky speedos), Sunday is Open Modified. You can enter either or both classes.

Entry Fee is £15 per day / £30 per weekend.

So we have 6 rounds of the Stock Class and 6 rounds of the Modified class.

To qualify for a championship finishing position you need to complete 4 events in a class.
(e.g. For example if you work Saturdays you can just do 4 of the Sundays and you would get a championship finishing position for the Modified class.)

Entry details will be posted on here and the BRCA website in due course.

Full directions, hotel lists etc will be distributed in due course, and will also be in confirmations of entry.

Other Info

Finals are of the A-Z variety, trophies to top 3 in each.

The stock class is for 10.5 brushless motors from the EB list and speedos set to run in ‘blinky mode’. A list of homologated speedos will be produced by the electric board soon. This is likely to be very similar to the exisiting list used by ROAR in America, so use that for guidance
The Open modified class is for any BRCA EB homologated motor and any speedo. Dynamic timing advance and ‘boost profiles’ are allowed for this class, so there are no restrictions.

There are also separate championships for Formula 2 and Formula 3 (All drivers are placed into a Formula based on their ability, by the qualifying officer) this runs over the year and is based on the same format as the Open or Formula1 championship described above.

So essentially at events you qualify and race against people of roughly your own ability, there is a Championship for drivers of all ability to chase, and you don’t have to do too much road mileage to qualify for it. (Though I would personally recommend making the effort as they’re all excellent meetings.)

The timing system used is RC AMB; personal transponders are required.

European Championship 2012 – there isn’t one as the Worlds are in Europe (see below)

World Championship 2012

Heemestede Holland, sometime during the summer

Entry Requirements:
Do you want to go?
Let us know when we start asking who’s interested in going – the UK will be given a number of places that will be allocated by applying the handicap to the championship listing. Having said that, at the last worlds in Germany pretty much everyone who asked for a place ended up getting one.

Changes for 2011/12

Blinky speedos and 10.5 motors only for stock
Open modified only for Sunday (sports mod no longer exists)

Anything else that needs clarification, please ask away

Very welcome at all 1/12th nationals.If interested in class ,its a good place to get information advice etc.
So dont be shy ask questions, 100% of drivers only willing to advise and give help .
