It's been interesting reading Facebook comments about the car. Dirt racers seem really happy and are surprised by how stable it is.
Carpet racers seems to be split between people who think it is great and people who think it understeers.
For me, it understeers.
I think the answer is in the front geometry somewhere because springs/damping alone haven't made enough difference. I have a few things I want to try but will be a couple of weeks before my next track visit.
If you like a planted car and are willing to hustle it into the corners you'll probably be happier with something close to the kit setting. I can only drive smooth and I'm not happy yet.

Got a couple of team drivers at our track and a variety of AE Cars, from what I can tell they are getting the cars to rotate fine on our tight track, I think one of them played with some caster settings and I am assuming they are not using AE springs, especially in the rear due to the available spring rates AE has versus what CoreRC and / or Willspeed has for the rear, similar to what they were doing with there B6.4s locally..

Interesting, forgot about the WS springs - Willspeed Springs - 13mm
Anyway, the Willspeed springs work well, fit our 13mm shocks no issues and look like they fit the AE shocks fine too so you don't need to buy anything additional to get them to work like the Core-RC Springs. I could see the Red 2.25lb and Green 2.35lb springs being great options to compliment AE's 13mm rear springs, maybe even the heaviest Blue too which is 2.5lbs depending on your conditions and driving. Probably only thing I wish was a bit better was how the shrink tubing fits the spring, as it can be a slight pain putting them on at times, maybe a combo of color and shrink tubing would be nice.

Also i have seen alot of people mention the hall brothers setup but all i can find is their setup for cork floor, not EOS carpet, does anyone have any info on the EOS carpet setup for the b7?[/QUOTE]
If the Hall's carpet setups aren't on CML mine will be very soon. If you race at Midlands speak to Zak Smith, I've helped him with setup and he is flying with the B7 now.
Hi Roger, I found similar positive results in a damp shakedown on astroturf at coastal model car club. While I had no timing and I was the only one on track I would mirror what you said. The car was set up for dry really when I headed out but it rained on the way. My set up was far from ideal and it far too miserable to mess about with many changes, so i basically pushed the battery right back, 4 degrees of toe in, 2 anti squat and put a bigger pinion on (7t motor). I had 2mm pistons in with 1.8 holes front and 2mm rear, orange springs front grey rear. I would say much more to come just from getting the springs and oil correct ( also rear arms forward 2mm). I was very pleased with the car and felt it was probably better than my normal wet car.
Glad to hear that you are finding the B7 good in low grip conditions.
You have some eos setup on petitrc.[/QUOTE]
When looking at EOS event setups remember they have to run ancient front tyre design ;-)
I've not run mine yet, what KPI setting where you running on the front hubs? Will run mine outdoors poss in the coming weeks, pending weather, no plans to head indoors again this season.
I've only purchased the B7D, pretty much gear diff and roll bars are out of stock. The roll bars on astro setup, wonder if they'll be needed for the dry.

Not sure about ARBs on dry astro, personally I doubt we'll be running a rear one, possibly a front one if we need to tame steering and/or aid return from roll. Too early to tell, a dry track to test on would be lovely but I don't think there has been any!

My work has been focused on getting good turn in with the KPI2 blocks on the front, something that wasn't too difficult but I will admit to adding weight around the servo to get it to hold it's line when biasing the geometry to corner entry.
Seams to benefit from a lot more weight up front for carpet racing. I've gone for the heaviest servo I can find now - and I've stuck the old B6.4 weight plate underneath the B7 plate so I've got 46g of weight there as well now.
Once a brass weight plate appears for the front cut-out and a steel front bulkhead I'll probably go back to my regular servo and ESC weight plates.

It is my intention to avoid a heavy front bulkhead at all cost, or certainly try to. My reasoning here is that although they aid mid corner steering they significantly reduce the car's ability to change direction and be responsive, no weight will be added in front of the servo weight pocket if I can help it and I honestly don't think it will be needed.

Those pistons are in the right area, Personally I am running v2 Yellow springs all round, front and rear shocks in outer hole on the wishbones are I find that although it gives a similar wheel rate it feels a like more nimble without becoming snatchy. For my personal driving style I didn't like any combination I tried using the middle hole but if I was forced to use the middle hole on the front I would be on something like a V3 Orange.
KPI2 seems to be the sweet spot for me, I want to experiment more with KPI but so far KPI1 seems to be too biased towards corner entry to suit me and KPI3 too biased towards mid corner steering to suit small UK track so KPI2 is the Goldielocks setting, or so it seems with the limited running I've had.
Not sure about ARBs on dry astro, personally I doubt we'll be running a rear one, possibly a front one if we need to tame steering and/or aid return from roll. Too early to tell, a dry track to test on would be lovely but I don't think there has been any!
I think it is partly a driving style thing, partly a track layout / surface thing and a LOT about the tyres used.

That seems a lot of extra weight. I run a full size servo anyway, ETRONIX ET2061 which is light and some of the low-profile servos weight the same! On carpet I have gone as far as 5g on each side of the servo mount and 10g in front of the servo. TMG will be releasing a brass under servo weight very soon and they have been kind enough to provide me one to evaluate, that evaluation is that it is a must have item if you are going to run Schumacher tyres on any carpet type.

Interesting, I messaged Dave B the other week whether he was doing much, but no response. I was initially after some 2mm pistons are most places out of stock, but also watching to see if people moved to the 2.5mm
I've not tried the fusion 2WD tyre, but then indoor running mm err yeah. Not even interested in what goes on the GP event in a few weeks. Now the 2WD dry astro choice, there is something more important

All good to hear, will be fitting the RSX3 KO into the car this week after debating dropping £££ on a LP servo, will get the car up and running first.

Re weight, hopefully I’ll have a spare steel weight left from my B6.4 clear out. Will be interesting re weight setups too outdoors.

I've quite a few older spur gears (none octalock) do they still fit a b7?

I am presuming that the Anti Roll Bar Hardware kit only provides enough for one end of the car?
