no I don't have them, I only have the 3 and 2.5,

Initially on club nights the car was happy with the 3, but I switched to 2.5 for the day meets which helped a little, but all the things I tried only ever seemed to take away from rear grip out of the corner and didn't really fix the entry/mid understeer issue. Which makes my think I have missed something

How about this setup. Also you can try the body he is running as well. Should offer a lot of steering for asphalt.

Forgot to post setup.. http://www.petitrc.com/reglages/yoko...ei20130804.pdf

http://www.petitrc.com/reglages/yoko...i_SMA20121014/

The car was very good with 32 compound tyres that I was using on club nights with a much cooler track when I first ran the car, the downside with these tyres is that they only last 5 runs. On the weekend just past it was very hot and very high grip. So I switches to 36 and tried both ride and muchmores, but with both it just wouldn't turn in.

I just removed the steering bridge to see if that might help with some more flex, and it seems no one is running one anyway, is it worth while removing the top motor mount screw as well ? any downsides to doing this ?

anything else I can try ? help ... I am hopeless at trying to setup cars

Thanks.

Beth.
Shorten your front wheel base
Take out the 2mm. Center links put 0.5

The steering bridge makes a huge difference to front flex and initial steering. Remove it completely for more "bite".

I wouldn't remove the screw above the motor mount. From your setup sheet less shims on front bulkhead will increase steering and also the thinner top deck will give more steering.

Oh and the black version is the best looking car I've ever seen
You know what, i noticed this weekend that my chassis is slightly tweaked, especially when i put the battery. For the last races, i had to push the car down with a bar and tighten the top plate after the battery was strapped in.

Any ETA for the release dates of the 2014 kit or upgrade kit??

Ran my BD7 RS yesterday at the CWIC

the amount of grip and steering it will give you on a good setup with yokomo pink spring front blue rears is unholy, its a shame i cant drive it hard enough to reap its rewards but hopefully next time round i can push it harder because its just such a smooth, quiet and fantastic handling car, but out of the box the RS will need roll bars, springs, full option bd 7 drive train etc but the bulk heads n susp blocks are fine.

if you lack of mid steering, your should try 6 deg c-hub. it's might help your problem.

On the setup Sheets it says SJ and WJ for the drive shafts, what is that?
I thought the BD7 RS came with Pink and Blue Springs?

I think the 6 degree hubs will make her initial under-steer even worse that what it is. I tested 6 degree on carpet and I lost my initial and had too much exit steering. I went back to 4 degree and it was good. Next I would like to try 2 degree. This past weekend I ran 4 degree with anti-dive (.8mm) and the car was great. A lot of changes this past weekend!

SJ- Single joint
WJ- Double joint

RS Kit springs look unique to that kit
Not standard BD7 White springs with Pink/Blue marking

Mac:
I also found this to be true with the 6deg chub, more exit steering, not so much on entry or mid

Man that Black Special kit wow
If you already have a Blue kit....
It's like the Hot chick flirting with a married dude

The exploded view in the RS manual says they are Black YS-1465L springs all around.
