Did anybody thing with own brains at all in AGM.

Why is sintered rotor not legal 2007???

Maybe because some wants to drive in HISTORIC class with brushed motor

It was already desided that it is legal...... but then BRCA did found an old rule......

Also i heard that some manufacturer said that the sintered rotor gives 200W more output

Sinclair

The BRCA obviously used their brains and knew what the existing rules were relating to technical changes beforehand.

It gives those Manufacturers, who don't have them, time to test sintered rotors and delta winds. Too many changes at the same time.

Now they should consider allowing rare magnets in brushed motors and allow them to compete on a more even footing.

He guys!
Wow, 5 cells, good move EFRA!
What does that change?? Answer: NOTHING!!
In a half year we have 3 more cell upgrades with even less
IR and more capacity and speed and car/tire wear will be the same.

See ya TC!
Long lifes 12scale!

P.S.: I would disallow Lipos as well, I don't think thats a good idea.....

At EFRA level, should be 6 cell, and at a National level, go back to a turn limit, but a timming lock, like a 19t, so you can't crank the timming up to 50' and fubbar a motor in one run.

So you think that locked timing and a motor limit is the best solution for modified?
Why's it called modified again....

Rare earth magnets are legal for modified in the BRCA so i guess we'll see when they appear.

Im getting bored of all this

But heres my opinon anyway.

If its the power of the cells thats blowing up our motors and speedos (even though i never see a speedo blow up purely because of TOO MUCH power)

Then whats the problem with just having brushless as the norm? You may argue that they thermal but thats a hell of a lot cheaper than throwing a wind. And they are proven to be as fast without thermalling. Not too mention the long term cost effectiveness of brushless technology.

Also, brushless IS allowed so why are we switching to 5 cell again???? ^o)

I may not know all the facts but from where im sitting it looks as if motor/battery companies have a fair influence on what is going on.

Rare earth magnets are not legal in the BRCA.....

Todd Hodge

Do you race in Europe?

pheyhoe

Im pretty sure they were legalised at the last AGM.... ?

Robfo

No, my mistake. they are in the brushless but not in brushed

From someone in the UK, I believe the 5 cell rule will be a good one...And yes we tried both 4 and 5 cell options. Contrary to popular belief the 5 cell car was as almost as quick with the same motor same gearing as cornering was faster...more grip and easier to drive. The only problem with 5 cell is that under its current set up, (no motor limit) cars will be quicker using a 6 or 5 turn motor..So effectively we may have achieved little in reducing the speeds of cars. Perhaps over the next couple of years we will move towards 4 cell who knows. Notwithstanding that, the problem with electronics failing should be reduced...

Talk of why this is necessary is pure and simple - electric racing across the world is in decline. And this is at a time when cars are becoming faster and faster...things are wearing out at an increasing rate and cars are becoming uncontrollable (in most peoples hands). Perhaps the view is, that by reducing speeds, costs and demands placed on controlling an 70mph missle successfully, this may attract more people into the hobby.

Comparing Nitro and electric is perhaps eronious...A nitro car has an ally chassis and thicker components. It handles nothing like an electric car as a result. Electric TC is faster at present than Nitro, but the materials used are more fragile. So you can either make a electric car bomb proof or slow it down. The beauty of electric TC at present is that the cars handle incredibly well with all different types of motors in them. Copy a Nitro car, and you have lost its finesse. Anyone tried a NTC3 with a stock 27 t motor in it??

Racing is not all about going faster and faster in a straight line lets face it any fool can do that, it is about beating the competitor within a level playing field. But there needs to be others racing and unless we can turn the corner there will be very few left... So before we slag off EFRA's decision, perhaps we need to think WHY this was done..

Talk of rare earthed this and that is meaningless, talk of lipo and brushless as the future is too..Less people racing means a smaller market, a smaller market means less profits resulting in less investment....you wanna do 100mph?... chances are you will be doing it alone.

It is an option that seems to of been over looked, the issue when there was a turn limit before, was people cranking up the timing till the point that the motor was duff after one run and needed a full re-build. If you limit the timing to a set point, then you can't and the motor will only produce a set amount of power. Yes you would still be at the mercy of cells and buying ones with good AV, but aren't we doing that now.

To be honest, as a buggy AND a saloon racer, the thought of having to butcher packs up if I wanted to run mod, I would rather go for the slower 19t and be done with the headache.

I like any ruling that causes people to freak out.

Personal amusement is my #1 priority.

No, we voted against it..As for brushless, it was left to see what EFRA did before the EB made a decision.

reduced voltage :

(+) Longer life for comm and brushes
(+) Less tire overheating
(+) Reduced speed = reduced broken parts
(+) Car setting a lot easier for beginner

(-) Need additional 6.0V receiver battery if running 4 cells
(-) 4 cell stock is way too slow, so say goodbye to stock class
