Check these out; the main structure is cut from 6AL4V titanium sheet, while machined 6061 aluminum components mate with the hingepins and pivot balls. Stainless-steel rivets hold the interlocking system together, and Hardcore says the arms are the lightest alloy units available. We believe them.
HCR-05314; $300

I have heard some good things about hardcore they are a bit pricey for me but i guess you get what you pay for

I think I'll get the Traxxas setback arms for the Revo instead. :cool:

you guys gotta remember its titanium... which means alot more machining and tool cutting hours then aluminum... you have to have ALOT more coolant, too. $300 is actually a pretty good price, taking into mind the cost of fabrication...

Honestly, there isn't THAT much more machining done. They have special bits for cutting titanium already..they've been making parts for years now, so it's not like they have to make up for astronomical r&d costs. As for the price of materials, there's about as much material in a set of a-arms as about 3 sets of titanium turnbuckles... so if you sell 3 sets of turbuckles for roughly $20 each ($60), where's the extra dough coming from? Oh yeah, and the turnbuckle sets have more peices to be machined and just as much machinework done also (flatspots, lathe to make them round, tapering, and threading)

Not to start an argument ;) , but I have to believe that machining turnbuckles is significantly easier then machining suspension arms. All you need for turnbuckles is a lathe and a die. Making the arms the way Hardcore defiantly means more material and more machine time. More material because you start with a hunk of metal (although it does say titanium plate, so I could be wrong) that you "machine" away until you get the final product, and more machine time, because, well, you have all that material to get rid of! :) And we can't forget that it takes time to design and test new components, which unfortunately can translate into a higher cost to us, the consumers :( . But I do agree that they already have the equipment necessary to fabricate this stuff, so that shouldn't factor into the price. But all that aside, I really want to see what they look like! :)

No pictures?? BOOO! ;)

And I could find much better things to spend $300 on..that'd be more then half way to completeing my brushless and lipo RC10GT conversion I want to do :D

I see bulkheads breaking constantly! Stick with Flextec, the new Traxxas ext arms, or RPM arms.

IMO they look killer. They are made from titanium plate, not billet chunks of titanium btw.

Titanium is about $90-100g. density is .174/in3 (4.82 g/mm3)

pretty good price. i would buy them if i had a revo/the money. super light, super strong (only 60% heavier then AL, but strong as steel). JMO.

Wow, that's a really different look. I like it, but wouldn't the arms get clogged with dirt and mud rather easily due to the gap? If they work well then I guess that wouldn't matter, at any rate, they're cool looking. Too expensive for me though.

Very unique to say the least! At least the guys at Hardcore are thinking and coming up with new ideas.

These don't look at all bad, but IMO the FlexTek arms do look to be a much better design and concept. Also there aren't any bushings where the hingepins would pivot, so the ali looks like it would slowly develop slop. These arms are probably very strong and I don't like to criticise, but they don't look very flexible at all....one solid whack and I see busted bulks...

I agree, +1!
