About this creation
Hola MOCers! Today I need help with a new R/C car I started to build yesterday!


Underside just for the heck of it.


Mow on to what I need help with.


Here is my problem. I have to have return to center, but it does not turn the wheels nearly far enough. Does anyone have a solution?




The drive train.


Thanks for your help! :-)

The pin on the end of the lift arm is catching on the RB I suggjest using a 2stud lift arm instead of the 3stud long one

you could always use a larger cog/gear on the steering rack

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

Quoting Joonmin Kweon 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.
Generally I do it every day. :-)

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

Quoting Halhi 141 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...
Yes I have tried his before. It works well. Still experimenting with different systems.

Quoting Halhi 141 Pretty much, and it wouldn't be able to turn right.
here it says different. http://www.technicbricks.com/2009/09/tbs-techtips-26-return-to-center.html

Quoting Halhi 141 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...
So by one direction do you mean, It would only spring back when you turned left? for example.

Quoting Halhi 141 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.
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?

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?
