Spoke with Frank a few weeks ago, slight revisions to the chassis plate. No cell-slots and a few other minor details. Not really a new version, just testing a few things.

I'm more interested in the solid lipo chassis. From looking at the video from the worlds, something new is coming......I just want to know when. I need a new 12th for next season.

The new Black Art prototype tub looks sick!! When I was in Rome, @ CRC, I checked out the first version tub, and it's very impressive. This new version looks even better.

Really diggin' that upper hingepin brace as well.

Hey guys....

Very recently got one of these which has been my first ever 12th scale. So far I have raced it twice and with mixed results. First outing was simply off the pace and spent most of my time trying to get the car to drive out of a turn (10.5). 2nd outing and I found a lot more speed managing to win the night at one of the local clubs. How ever on both occasions I have been looking for a fair bit of balance from one end or the other. Now I race on asphalt which is hardly the normal for most 12th scale guys but thats what we have around here. I am wondering what sort of setups do people run with these chassis on asphalt.

Currently the car is very fast... I had traction rolling problems last time out but only near the end of the race off power. At the start of the race its is smooth and quick but goes off during the run and becomes oversteery off power.

Last thing is I found that the car likes even toe or toe out on the front. Toe in produced a car that kinda "wiggled" in the turns. Is this normal as my TC definitely does not do that.

There is a collection of base and also team driver asphalt setup sheets available here. If you are presently running lipo pay attention to 2009 and onward sheets.

Problem is how to compare the big differences in grip levels from different asphalt tracks. Dragonfire didn't just take the win the other night, he went 0.3s under the lap record and set a new 8min record too. This was on the second ever outing for him and the car!

I am sure the first time out was a lot to do with tyres and goop than anything else. It was on a track that offers very low grip for 1/12th racing. Seems to me that when the grip is low enough, going too soft causes problems on power?

I am finding that with light weight oil(like the kit oil) in the side tubes that they become very inconstant in their operation. The inner part of the tube seems to break free of the tube and offer no damping at all.

Yeah I looked through all of them (about 5) and made some changes based on that. However it would be interesting to see what average drivers are doing to get around the track. So far I am happy with what I can do with the front and rear springs, a little confused about dynamic castor, and really confused about what the side springs are actually doing. Is there a detailed setup guide for link cars (more than the manual)?

I guess you already know this one; Richard Chang's 1/12th Chassis Setup Tips (pdf)
Also Xray XII Set-up Book

I'll check out that article so thank you. But as for xray I always disagreed with a fair bit of their TC guide so I will avoid the 12th guide

Well I just read the xray guide and it reinforces some of your findings. Particularly when it says heavier side damping being less unpredictable and heavier shock oil gives more forward drive coming out of the corner.

It also mentions narrower rear track giving more on power rear grip too. Might be something to try on low grip asphalt.

1. Dynamic caster reduces the caster angle as the suspension is compressed. As you drive into a turn, the outside front wheel becomes loaded, and the suspension compresses. As the kingpin moves more towards vertical, the car should actually gain steering. The three different blocks allow you to tailor the handling of the car by altering the amount of change the car can undergo during a turn.

2. The side springs are there to support the chassis as it rolls under cornering. Generally, the more the chassis can roll, the more sidebite the rear-end will have. The downside is that the car won't change directions as quickly.
