By stock bumper, are you referring to the piece that attaches to the chassis with the two screws and nut?

Has anyone tried the 2006 competition spec chassis? If so, what application does it have?

New aluminum arms and redesigned steering levers are up on Corally International.

The new chassis moves the batteries quite a bit back for more steering. It's thin so it will most likely be used for asphalt.

I thought it would be more for asphalt also, but then I noticed on the set-up page on corally's site that Mike Nelson was using it at the recent Novak Race.

Depends on what you want the car to do. The thin chassis is usually designed for asphalt and the thicker 4.0mm for carpet, although some drivers have been known to try vise versa. The #79337B is the new chassis and is pretty thin. The major change is the battery location, but weight placement, etc., have also changed. If you use the optional offset motor mount from Specialized RC you will need to remove some chassis material to fit the motor too.

The competition spec chassis has that stiffening plate too. Corally says it's for "high-traction carpet," though presumably, they mean rubber tires.

By moving the battery back, all the weight slots on the chassis behind the battery are gone, making it hard to use that area to add weight if you're trying to balance a LiPo. For those of us that are trying to move away from NiMH, that's something worth consideration. It concerns me that the Phi seems to use this new configuration, but I'm sure there's ways around it. I'm guessing not enough people care about LiPo (yet?), so who knows if the aftermarket will do anything to ease the pain.

Since the chassis is thinner, if you were going to try it for foams, wouldn't you want to use the standard roll center mounts to achieve similar roll center to a 2.9 chassis with the optional low mounts?

I was wondering why would moving the battery back add steering? I would think that this would add rear grip....? Please help me out with this one....

Swing weight..Rear steer like in offroad cars..Moving the battery forward will yield the most traction, move it back mo steering ..hope this helps..Bitt

Quick answer:
It adds off power steering because there is more weight in the rear that can be transfered forward .

I see, I was thinking of static wheel weights but this is about transient weight....hmmm by the same token, wouldn't the rearward movement of the weight "on power" take away steering? So it would be "more" off power steering in exchange for "less" on power steering?

Uptravel plays a major role in how much weight is transfered at either end of the car (which you probably already know). The new battery placement probably balances out the car a little more, hence giving the car a little more steering where the old chassis needed more tuning to get enough steering. I've never had a problem with on power steering, but I'm always in search for a little more controlled turn-in.

So with a heavy nose you run less rear droop, the rear doesn't transfer because the weight is on the nose and rotates.

And with a heavy rear you run more droop, the rear transfers more weight to make it rotate.

Interesting..... which is better? carpet? asphalt?
