I think you do...should we do some sort of poll?

Can you PM me on buying 2 sets? Price, method of payment, etc.
Thanks for the research and work on this item. Now you should move on to top mounted servo bracket. These are needed too by CC01 builders!

Just an updated on Ver. 2 of the knuckles:

The print ended up sub-par, because I tried a different color. I don't know how the dyeing process affects the quality of the plastic, but this one gave it some porosity.

For now, I think that virgin white, and black are guaranteed, and will take tapping easily and hold bearing tolerances.

Machining Update:

I tried to get a quote on machining out of aluminum, and it is cost prohibitive for the geometry of the item. Lowest quote I got was $45 each for a quantity of 50. As an amateur machinist, I don't think I'd want to fixture this thing myself even if I had a CNC setup.

Bonus Update:

I learned that a marked percentage of aluminum overseas "upgrade" parts are initially cast (using the original plastic material for the mold) and just cleaned up with passes from a lathe or mill to give a "machined" finish. I think that sheds some light on how no-name parts for a relatively new kit come out fairly quickly at relatively low cost. Will dig into this some more.

Can we glimpse the turned links?

Hello...keeping this thread alive..

[K.O.M.]

Hey all, thanks for everyone's patience. Unfortunately, I currently have no way of hosting additional photos since Photobucket decided it was time to cash in.

I'm currently on vacation, with no access to my computer,but I will do my best to get some images up.

A few details:

-max tire width I would recommend is 1.45"; you can possibly get a 1.5" tire on there, but you will have to shim the front axles to get every little bit of slop by placing the shims between the outer bearing and the cross-pin that indexes onto the wheel hex (a picture would be nice )

-steering tie rods need to be 4mm longer than stock, or each rod end needs to be 2mm longer minimum

That's all I've got until I can sort out another 3rd party web photo host.

Officially available on a first-to-try basis:

might catch some heat for this, but I want to build a CC01 drift car, and these knuckles are a MUST!
on that note, its going to be RWD with gyro. combined with eliminating front axles plus these knuckles I should be able to get some insane countersteer angle!

I am down for 2 in black. do I order from you (when you return from vacation) or do I just go and get them on shapeways? never ordered from them before.
