How many insert, wheel, and air hole combos does that still allow?
IMO if we have to run rubber, control is the only way, but they should be premounted, at a price where the tire supplier is not making a killing on a closed market. With proper scrutiny to be able to prevent tire pooling and extra sets.

In my view, a controlled rubber tyre is a great initiative for the following reasons:
• Provides a level playing field for everyone.
• Reduces the cost of competing.
• Reduces car setup time not having to test different compounds/inserts/wheels.
• Reduces the equipment I need to take to the meeting.
I only wish it would be feasibly to have a controlled traction compound or no traction compound to reduce luggage space and testing time as well. I must be missing something as I really don't understand what the fuss is about over controlling wide ranging items like tyres in our sport.

the same brand and shore could be used, no different to rubber rules and again half the price.
And also it becomes extremely expensive when you have to buy tyre warmers and all the other crap that goes along with rubber tyres to try and compete with the big boys
and whats the good of keeping a tyre the same for the whole feild when different motors can be used 4.5, 3.5 or brushed motors
i know someone is going to say because a particular company sponsored the event, but im just pointing out some things seeing a few people have said its good to make everyone use the same tyre , just doesnt make sence even down to different packs making a huge differance.

just a question why arent foams considered ? more grip less fu#*n around and half the price , and better wear

The "big boys" will always have an advantage-they have talent and abilities the average racer does not posess, and whilst some of the skills can be learnt(car setup etc) some are just natural abilities.
I am sure Jake Zarb is part Jedi the way he can drive a car.....he just knows what is going to happen and can take action to prevent it. And he would soundly slap 99.999% of other racers, regardless of the restrictions placed on his car or tyres or whatever. Same could be said for any of the so called "big boys" but when you put people of similar talent and similar equipment in a competitive environment, thats when they need to push the limits of thier own ability and start to make poor decisions and taking another driver out is one of them. Look at all the "control" classes of full scale motorsport and see how many races are decided by accidents/driver error. Unfortunatley in 5 minute R/C racing a 10 second period against a barrier is sure to kill any chance of winning- you would need to be about 1 second a lap faster than the entire field to make up the lost time-and that is simply impossible at the A main level.
Full control tyres is the best way to level the playing field for the mortals amongst us. In reality most of the previously unobtainable stuff(big batteries, sick motors etc) has been accesable to most racers, albeit at some cost, but no-one ever says this is a budget sport either.....

This approach allows drivers on a budget to opt to only check in one set, and to re-use rims and inserts if they want to (or even to check in already used tyres).
It doesn't control inserts and rims obviously, but our experience suggests that for most of the field, that doesn't matter. Most people have a fair idea what insert and rim they like, and while the front guys might test a couple of different combinations, spending has not been as out of control as you might be suggesting.
For the club running the event, it makes organisational life heaps easier. No tyres to source and administer, no "glueing zone" to monitor. It lets competitors source their tyres from their favourite shop.
In my opinion and experience, the system actually has worked well. Racing has been close, competitive and cheaper than open tyre rules, but slightly easier to manage than full control tyre rules.
Come and try it out for yourself this October for the 2007 Qld Champs - on one of the best 1/10 on-road tracks in the country at the Sunshine Coast. Details announced soon!

lol...
I remember good old hpi/venom challenge at forestville. Sorex was the fast tyre. And we discovered 1sec/lap difference between sorex dish rim and ride 5spoke (soft) rim with the same tyre/insert combo (in 27t stock).
What do you think YOUR chances are of making the A's with that handicap. Even Jake would be enjoying the back of the grid IF he managed to make the A's.
The idea of being able to bring your own tyres sounds great tho. But you would still have to assemble them in front of a official and for 90% of ppl $40 is a hard price to beat anyway. Most events now allow you to run just one set for the day if you so choose. At any control tyre event I do, I always buy max sets so I have plenty of practice rubber for club dayz.

Then you bring in tyre truers, and cutting them down so small that you only get one run with them. To be competitive you will use heaps of sets and it will soon run in excess of what control rubber will cost

it was just a suggestion
and regards to foams i dont know where you got the idea you have to cut them down so small, at 63mm they are the same size as rubbers and at that size youll get a whole day out of them, i run A finals for 30mins in nitro starting tyre size of 60- 62mm and theres some left at the end, and theres a shit load more power up there bum than a 4.5 BL,
and a set of foams will cost $24 or there abouts , much cheaper
But like i said it was only a sugestion

A question about the stock class at the event last weekend. When I saw the rules for the event, I assumed that sintered rotor brushless would be a big advantage in power over bonded brushless and brushed, based on what I have seen of sintered up here in Brissie. What were the fast guys using in stock, and what of the LRP motor which was legal for this event (I haven't seen one of these run).

Also keen to see race results for this meeting if anyone can point me in the right direction.
Thanks, Keith M.

Damo zarb was running the X11 13.5, comes with a bonded rotor and looked very good, at least matched the power of the novak. I think it required a much taller ratio, i would assume will only be faster with a sintered.
Then again the LRP guys rate the 13.5 as a 23t equivalent.
Looks like the BL boys should pull some sort of standard for the motors otherwise parity will become very hard, although when running stock brushed, who doesnt use an epic based motor? Same thing may emerge in BL
