People ask me that all the time, and most with a lot of weird looks

It's the way my car in 06 was when I won the carpet nats, super swept and angled down from the saver to the knuckle. It's also the way I setup my akerman on the Xray FK04 Foam cars back in the day. To me it had always just felt smoother like that in high traction conditions, but for example if you ask Keven Hebert he will say the exact opposite!

In the end for me it's personal preference

This is an important point. You can ask for advice, you can copy set ups from Factory Bucks Racers, but in the end you have to find something that works for you. I'm with Peter on this one, though a bit less extreme.

I run it the same, it's a matter of feel. I have tried it at half the angle and straight, and I just like it that way better. Car was probably just as fast it just felt better at the wheel.

Hi,

"Back in the day"....LOL.... Dumas, myself and a lot of other drivers did a TON of testing with the Old School.

Without fail, we found that our cars (Original Carpet Knife, Rev. 2, 3, etc) performed better with that much tie-rod sweep/Ackerman.

Generally, the car is easier to drive, but also more efficient in mid-size corners. It was very easy to see back to back, that stock class drivers were finishing their runs with lower lap times from the 6-8 minute mark while running that much Ackerman.

There is definitely a larger discrepancy at high traction "Big" races. For local club racing, I don't think it really changes much, but on really high bite tracks it helps the car be more efficient and easier to drive.

Here’s a picture of Donny Lia’s Rev 4.5 from the 2007 Carpet Nats.
http://www.teamspeedmerchant.com/DonnyLia2007Nats.html

Full race report…
http://www.teamspeedmerchant.com/200...arpetNats.html

We won all three classes that year (Stock, 19-Turn & Modified), all with the Old School fronts, all running the same amount of Ackerman.

That was the last season we ran the Old School. With the advent of Brushless motors and larger, heavier round cells, I felt we needed some reactive camber in the front end to help the cars get around the track. It was much more of an issue with Mod at the time. Hence, I released the Formula Front Suspension for the following Carpet Season. Steve Boice debuted the Formula Front Suspension with a victory in Stock at Las Vegas, and Dumas TQ’d and won the 2008 R.O.A.R Mod Nationals.

But….you know what they say….”The more things change, the more they stay the same”. With today’s light and nimble LiPo cars, we started testing the Old School again, and sure enough it worked great. It didn’t take long for us to migrate back to the same Ackerman we used to run “Back in the Day”. Same results….easier to drive & more efficient.

Sorry for the long winded answer, but it was a good question.

Have a great day.-Bruce

Tony Neisinger always ran with a lot of ackerman like that too, still does.

Only if you use Hyperdrive front mounts

Why on Earth would you wanna do that? I watched Joel Vatour's car run at the Champs this past weekend, and the Old Skool front-end is all you need.

Or maybe a CRC Prostrut if you're so inclined.

Yes if you purchase the hyperdrive mounts. I use this for testing sincev(Wes & I) don't have a permanent track to run at and very limited track time (once every two weeks). It allows you to try a lot of stuff quickly. For big races and instances where I have more time to tune and wrench, I always prefer the old skool front. I can apply anything I learned from the R5 front end to my old Skool front, and I get the added benefit of precision and durability.

I forgot to mention, any cars running the angled servo are running this much Ackerman, it just looks different. The plane of the servo saver is what you have to look at tho, and the Ackerman ends up very similar to what I use So it's more common than you think!

I'm going to buy a new 12th scale before Christmas but I'm trying to decide which one I want. There are only 2 I'm deciding over the Rev. 7 and the other is an American based car also. The last 12th car I raced was a Rev. 4.5 and I loved that car, fast with any setup and it could be driven hard.

I am wondering is the Rev. 7 the same way? How does the new inline setup work verus the old layout? What is the big diffrence with the new liner tweak spring setup? Can this car be driven very hard, I can't drive a car that has to be driven easy I have a tendancy to push things and I'm kinda edgy at times.

Thanks for any imput, I just want to buy a US made car.

Looks good, let us know how it goes! BTW the CEFX and AE foam bumpers fit the Rev.7 perfectly with the old skool front end and will save your chassis big time.
