Yes this rule the BRCA representatives found in the rulebook during the night and the next day they again opposed against allowing sintered magnets, I heard.

But allowing sintered magnets can not be considered as a drastic changes in technology so I really hope someone posts a appeal against this.

Going to 5 cells is allot more drastic change than allowing Sintered rotors

The sintered rotors will give us a litle more bottom end power and less rpm AND the motors will not blow up like with the Bonded rotors.....

Exactly!

Just shows that rule was found and used just as an excuse by those (brca & manufacturer?? ) who wanted to keep the old motors competitive...

Wasn't it Oscar who was against of these sintered rotors as they have +200W extra power? This is a funny thread...

To be fair i don't think they "found it overnight"!! I had been told about it before the AGM, so i think all knew it was there.

Let's look at it a different way. If i was paying full price for my kit, and i bought a Brushless system say 2-3 months ago, i'd want to be able to use it for a while rather than have it become uncompetative overnight. Because i think we all know that sintered stuff offers a lot more power and would probably make bonded stuff uncompetative overnight.

My own personal view however, is that i'd like to be able to use sintered stuff as soon as possible. Becasue of more power and improved reliability. I'll probably stay running brushed for the 06 season. We'll see, bonded may have advantages on some tracks.

Hey Matt,

You could just buy a Sintered rotor and upgrade your current system, no worries at all...

I had to buy a Bonded rotor for an EFRA Race we had some weeks ago, cost me 30$
So now I have "two" motors with different powerband

Eirik, yeah true. Simple solution!! Like i say, personally i'd rather run sintered if we're going to run brushless - i don't really see the point of waiting. MY view is that the guy that has bought his system is likely to blow it up, and that wouldn't be a good thing!!!

Just that i can (kind of) see both sides.

I know what you mean Matt, but it should apply for the 5 cell rule as well.

I just bought 4 new 6 cell packs..... now I have to "ruin" them to race any EFRA event after 01.01.2007

Buy one more then you will have 6 5cell packs

Just kidding,

Fortunately for us, racing season is over and by the time it starts again 5cell packs will be available here

LOL!!

We will run 6 cells in Norway for 2007, so I will have to buy some new 5 cells pack anyway....

I installed the ORION brushless with the EFRA 5 cell configuration.

It turned out pretty clean, as more space is now available for the electronics.

I would not at all be suprised if Orion and Oscar Jansen had something to do with not allowing sintered rotors in brushless for 2007.

After seeing how Orion operates in the last years I do not have much respect for them anymore.

with all those "selective" memories from the EFRA AGM you can make up a lot of stories

Take a look in the EFRA rule book and read it first before giving comments.
The BRCA reps were very well prepared for this meeting and all have very good knowledge about electric (on-road) racing and the rules for it !

The manufacturers reps at the meeting were advisory: there was nothing they could vote for or against. The meeting asked their opnions for some of the hotly dicussed items and that was it.

Just a thought, we have just completed the Australian titles where the major of competitors were using brushless ( Novak, Gm and LRP) and there was at least 4 sintered rotors that disintergrated (mine included) while running conservative gearing. After purchasing a new 3.5 novak it ran well until the 4th and 5th qualifier and final when it thermalled while I was in front.( 4 1/2 min)
Please dont think the sintered rotor is the answer to your prayers as most of the guys down under are having lots of issues with themals and now rotors exploding, effectively destroying the motor.
