Hey guys, ive been readin quite a bit on chassie design, and people do like narrow, but is there such a concept do you think as To skinny?
i have a smithy 3 in 1 and have an idea how to build a chassie as narrow as you could hide the motor in it built for tlt axles, in other words building the tranny to fit

so my question is, can a chassie be to narrow?

If it is too narrow you will not be able to get the right triangulation of the upper links to make it stable. You could always use spacers on the outside of the chassis to mount the links to get some angle back. Try making one, who knows it might just be the next best thing. Way to think outside of the box.

I've tried one for a clod at 1" wide and didn't want to tinker with it anymore. Couldn't really get the whole setup to really mesh...but looked cool as hell.

The benefits of a skinny chassis are a narrow contact patch at the bottom. I was trying to achieve that exact same thing when I designed the ARC. It has the narrowest skid of any chassis that I know of (for a competition 2.2), but it still give you plenty of upper link triangulation.

Check out the build here: Harley's "ARC" chassis build

Also another big thing is that you need room in the chassis for whatever equipment that is needed (trans or battery or whatever).

Also, I tried to design an Axial chassis as narrow as practical, about 2".

Thanks for the advice guys, i guess the real problem (allthough not a problem realy) is getting the proper distance on upper links, everything else should be good. im inthe process of moving so this well take a bit

Harley, nice pics and info, is that molded or machined plastic i see inthose pictures? im interested in making some molded plastic parts....
very nice chassie, i like seeing your version

my whole concept evolves around the custom tranny, a chassie can only be as skinny as the tranny your able to fit in it realisticly.
no point in having a 1 inch wide chassie with a motor sticking off the side like a tumor

true, but the motor has to go somewhere, and people don't like it up tp for center of gravity reasons.

I could almost see mounting an r2 on end, motor high, with chassis plates on either side of it. hmmm... something else to play with.
