@ Airwave
I noticed that when I changed the inserts to mid high position. I think the default setting roll center is already too low so I went the opposite way to yours.

I run 17.5 on the black rug and I am using the mid-high position as well. You have to make sure not to put the "high" blocks in the low position or the arms will actually be lower than the bulkheads causing a bind. I am going to be trying out the new rrs links in the rear today. Been working on a good setup for awhile now. Once I get it to a decent point I will post a setup sheet.

I think Airwave knows that but he's prob trying different things.
Zeiler, do you use any other option parts? I've been sitting on my shopping cart with all those option parts a while waiting for VTD to be available.

I know everybody thinks it is already too low, but I'm running Volante 36R without additive, so I really need the car to roll to load the tyre and make it hot.

I'm pretty sure that on ETS carpent or Fasttrack II the roll center would be too low... This is coming only from a visual impression, when I run my VBC I can see the car roll and tyres temp is ok (around 47°C), my P4X seems to be too gentle with the tyres and the temp rarely get over 40 °C... So I'm trying. I'm also pretty sure that at some point I have to switch for the light CF chassis, this original one is too stiff for low traction asphalt.

Don't take my opinion for absolute truth. :-) I love reading other feed-backs on the car, on carpet or asphalt.

You have some option parts right? I'm running stock still. The car feels pretty stiff as you said. That's more so after I changed the piston from 2 to 0 hole and up'ed the roll center. The car starts rolling at entry of corner and then feels as it it stopped rolling and lost traction in rear unless I drive very smooth. Both front and rear slide together at high speed corner entry. Not sure if it's RC or 0 hole piston but I'd say it's 0 hole. I think damping is too much that it locks. Next time I'm thinking of trying 2 hole again. I began to understand why people get option parts as the car seems pretty hard to set up w/o them.
In regards to tire temp, mine records 105 inside-upto 115 (43C) outside in F. This is when I run 32R-36R sorex in ambient 80-90F, track 100-120F.

Even before I got the upgrades, making the changes to the 2h heave and 0h roll dampers were a massive improvement. Surprised to hear its difficult to setup like so

I changed roll center at the same time too. And I don't know about yours but the traction is low to medium in our local track. I think it's generally easier to drive the car with thicker oil (less piston hole) but the available grip wasn't just there with my set up. The car was still drivable if I made sure to squeeze brake and throttle slow enough but by no means "easy to drive". The fact that it was ok at large sweeper but not ok at esses and hairpins made me more suspicious of piston locking.
This car's suspension is just so foreign and you have to take both heave and roll dampers into consideration at the same time and this makes me fight hard to get the right set up.
Anyway I hope I can find better one in my 3rd outing soon.

So is an updated kit expected this season?

According to Felix he hopes by end of year.

I was told in the Facebook that when expect one by the end of 2017. Making my decision between getting an A800XA now or waiting to see what Awesomatix and Serpent have to offer for 2018.

With 3 great, mostly conventional, cars in my stable already, I'm looking for something exotic to feed the R/C addiction.
Project 4x vs A800 vs GZ2. My preference changes with the wind and none of the exotics have everything I want but an updated Serpent sure sounds exciting to me.

Thanx to McFactory Racing for getting this sharp looking chassis. Havent ran it yet but will this weekend.

Thanx Mike M.

Tell me how long it took for you to get it from order date. I heard the guy's slammed with work and some have been waiting for months.

About 6 days

That chassis looks fantastic and I'm not just referring to the cosmetics - the shape of the cutouts looks a lot more purposeful than the the typical TC aluminum plate.
