Try to use 8066 steering, I have used it in a RC race car and it works very well.

Generally I do it every day. :-)

Sorry but I don't really understand. :) You are online! I thought now you might be here, and you were here! But sadly I gotta go, but I will be in MOC pages in Wednesday! SO see then! Do you do MOC PAGES everyday? IF so, that is good! For me, Sat. mon. wed. thu.

Interested? http://www.mocpages.com/group.php/22185

The only ways you can go about the steering angle in your setup is by using a bigger gear on the rack like someone suggested, or shorter liftarms to mount the wheels on - the gear method is definately preferred, and with the room you got, not a problem to even include a 24-tooth gear. As for the hockey shooting part you mentioned for return-to-center: I bought a few of those, and they work nicely, however aren't exactly centering most of the time, and some setups require two in a row to handle the draw-back-effect, which in turn might keep the motor from being able to turn the wheels completely. A good rule of thumb is it works okay in combination with a single PF M-motor with not much weight applied to the wheels (or whatever else you have). I think the method you're going for in your pictures is the preferred one.

it looks like Sariel's is the most functional and well designed, so I think I am choosing his

Yes I have tried his before. It works well. Still experimenting with different systems.

Hmm, maybe I remember incorrectly.... I'd recommend getting two of those if you will use them, so that they have more power to return to center. I found Sariel's method works pretty reliably though...

here it says different. http://www.technicbricks.com/2009/09/tbs-techtips-26-return-to-center.html

Pretty much, and it wouldn't be able to turn right.

So by one direction do you mean, It would only spring back when you turned left? for example.

I'm not sure. I had one of those, but I think it could only spring in one direction. 8448 looks like a good set. Too expensive perhaps, though, at current prices...

Thank you for your help. I have one question. woud this piece work?http://www.bricklink.com/catalogItemPic.asp?P=x928cx1 Also what do you think of the 8448?

Also, a structural note: I'd recommend using some of these: http://www.bricklink.com/catalogItem.asp?P=42003 to connect some beams that go across the width of the chassis, as donein the extreme cruiser. Making the chassis about three studs high might also help.

Try changing the gear that drives the gear racks on the steering. A 12t gear driving one of those gear racks from the 8070 can work well. Also, using a similar steering system, but without the gear rack and using some double bevel gears to move a bar in the middle of the steering system might work correctly.

Use a different rubber band?
