The upper arms are to reduce flex.

With that said... i am happy to be finally joining the arc family. Just hoping the 12.1 is at least as durable and as easy to drive as people clain its predecessor to be...

Tamiya did this like 400 years ago. Maybe just leave these new parts off.

I thought there might be some dissention when the pics came out. I think if the upper links were formed from plastic (i.e., xray) it would "bolster" this more. I will say I don't think I've ever run into a situation where that area of the car flexed too much (unless it was a pipe I was introducing myself to intimately). The turnbuckles create another problem where in order to set your camber you have to set both links. This causes undue stress that you really cannot feel at the wrench and may make a casual tap into something much more severe. This feels like "keeping up with the Jones's" but in a way that is very superficial.

The rest of the things on the car really do nothing for me. I can't tell you how many times I was looking to replace my outdrives on my spool and wished I could do it while it was still in the car. The low friction stuff I get, cause the non low friction stuff still has leaking problems even after "fixes" were made. Active rear suspension...hated it from day one. Adds more parts to the car for no real reason as if you are setting something like this...you are probably running a different car.

But to call this the 12.1...yeah, doesn't feel like it to me. Looks like an excuse to sell more parts as they've added a ton with no real upgrade to performance. Just my thoughts...sorry in advance if I've offended anyone.

OMG... What is the point of having such configuration... If you crash or if you are not attentive enough, you suspension can be totaly bent... Why not going for harder lower arms instead?

They are trying so hard for it to look like a Awesomatix, it is becoming comical...

Harder usually means more brittle.

Indeed but adding these "things" will absolutely not do the same. And the geometry is complex, on the inside, if the lower axle is not parallel to the upper axle, the suspension is not working proprely. That's probably why they went for ARS in the rear... But in the front, I'm curious to see how it move if you try old school toe out, like 2.5°...

Xpress has been using this arrangement for years and it hasn't been a problem for them.

It has been for me. The only day I've tried this kind of installation in the front of my XQ1, it just stopped entering the corner. I even stopped before the battery was empty :-(

I have put about ten packs through the Arc12.1 so far and am quite happy with the performance. Only thing i have changed is moving the upper deck screws around to increase flex at the front and stiffen up the rear.

Car performs great out of the box and has much more grip (which i would expect) compared to my 2012 bd7. Cant provide any quantitative numbers on lap time improvements but the fact that i am much more comfortable pushing the car around the track should equate to better times... i am also faster than people i was struggling to keep up with but this could also be down to the condition of our tyres at the time.

Regardless i am quite happy with the Arc12.1 right now.

Now that the R12.1 has been out for a little while & ppl would have had some time with them, what are your thoughts on it over the R12 ?
