I was looking into just buying some titanium bar stock and making my own...
Bar stock isn't terribly expensive.... $9-12 a foot
Anyone? Just need the od of them not anything else... 3mm, 4mm, 5mm....?
I will cut them for length when I get the stock...

Hi everyone,
Went through another pack this sunday.
Was not able to drive on our 1/8 track as it is being re-built.
So had to practice on the side (nice mix of dry short grass, sand, gravel, dirt etc...).
The thing is amazing; I was used to driving 4*4 1/8 buggy but this thing really has me wondering: 1/8 or 1/10?
The build is far stronger than my previous 1/10 (Tamyia and HPI).
If I had to buy another kit I would do it again no problem.
Have a good week,
V

Edit: anybody could remind me the part number for the motor mount if I am willing to go above 19T? Thx

hm, titanium bar stock eh...? I also wonder if I could harden the stock hinge pins myself to prevent this from happening again?

The ackerman arm? Either way, like anything else this is one of the items you can upgrade to save weight. You have to look at weight as a hole. Depending on what you've done already, you can have much more impact spending elsewhere. For instance: spring kit, drill a hole in shock cap for emulsion (free), carbon towers are all the ones that'll be the most significant).

So, by itself? Not worth it. But if you are going CF for weight savings, then yea include that in the list of items.

Gah, I already ordered a set, thanks though. I think I am going to experiment with hardening them. It looks like they got sheared off clean at both ends by the aluminum hinge pin braces. That seems odd.

If you make them harder they will break easier because they may become too brittle .

I thought about that, but I'm not exactly sure. Don't we harden outdrives to keep them from keying and harden diff pins and washers to keep from wearing? and isn't titanium harder that steel or no? Maybe because of the direct force on the hinge pin instead of cyclindrical type wear like on a diff pin is why you say that? I'm no metallurgist, that's why I'm asking.

I remember hearing somewhere, titanium isn't harder, but it IS lighter!

From soft to hard: aluminum, brass, T6 aluminum, bronze, titanium, mild steel, and stainless steel

gotcha, bashem is almost certainly correct then. hardening will more than likely just make em brittle. crap. Come on lunsford. My buddy snapped a pin yesterday on his too. same race and everything. Different jump.

If its a steel hing pin then you could try hardening them (thats if its a high carbon steel) however it will make them brittle and probably no good to use. If the force was being applied on top of the pin then maybe but the way the force would be applied I would expect them to break very quick.

If you are using Titanium you should not have to harden them, the titanium alone should be strong enough.

Im no metalurgist either but there are many different grades of titanium just like many grades of aluminun and steel...
