B6.1.. comments?
 

Hello everybody,
I was expecting comments on the first pics and information on the B6.1, but nothing yet.. So I'm gonna start the discussion!
By looking at the pics it looks like the new transmission is not likely to fit the B6 chassis, and if this is confirmed it's a real shame.
I would say that the new gearbox does not use the rear two narrow holes but uses instead the wide ones for the D block.
I would hope (and it would make sense) that the front and centre pairs of holes are maintained.
The C block is different, and does not use wide mounting holes as in the B6.
I am wondering whether I will be able to use the original B6 C block and still fit the new gearbox.

If this is not possible.. I will be really disappointed: why calling the car B6.1 if you cannot update the B6 to the new specs? Call it B7 then!!

you could just get over it

Haha :lol:

Yeah.. I guess so..
But not before trying! Let’s see when manual and part numbers will be available..

Its not possible - you will need the full rear end.

Brent Thielke is trying to come up with a way to use the existing b6 chassis by providing a paper template with new drill hole locations.

However if you wish to use the new gear box the C block will be needed as will the wishbones due to the chassis technically being shorter - the new wishbones re extends the wheelbase.

He has not confirmed it is yet possible - just something he is trying. However estimating the cost of the rear end, it won't be a million miles away from new car territory.

Shorter chassis? :o
Crap...

the new car indeed has a shorter chassis and it has been confirmed the parts won't swap over, it would cost almost as much as a new car. tbh the new car imo doesn't need much adding to make it better, i can't decide which to get for racing on astro turf.

B6.1
 

Personally I'm not bothered. I won't be changing my car. Only bit I'm interested in is the easy access diff.

Totally agree.. I think I will go for the 3D printed gearbox from Shapeways..

I'm more surprised no-one has commented on the B6.1D... I think it could be a good car for wet astro racing with the ball diff and its balance between a stand-up and laydown, but to be honest I believe the car is developed too much with sugared tracks and the pro drivers in mind.

Yes, you can get away with a laydown-style gearbox on low-grip. However the setup window becomes small, it (likely) becomes more sensitive to changes in conditions / grip level and one needs to have a very good feel and response to the throttle of the car. The majority of drivers are better off using a car with less ultimate pace but a wide 'operating window' and a forgiving nature, but of course many are not willing to admit that, not even to themselves...

Before anyone asks... I am willing to admit that I need a forgiving car more than one with ultimate pace :) It's also a more rewarding drive, being able to push to the limit without ending up backwards or on your roof every time you go over the edge...

Bit off-topic... anyway, still exciting to see Asso if anything is again leading the charge with the B6 instead of merely following competitors' developments.

A few of the guys at our astro track have preordered the 6.1D as all round car.

It'll be interesting to see. I can only hope I'm wrong about the B6.1D or Asso see very soon they need a kit with standup gearbox in their arsenal. Or both... :)

They have already said there will be a stand up gear box for car.

Assume the b6.1 comes with a gear diff as the pdf on the website has conflicting info

With the B6.1-type slipper? And only 3-gear, or also 4-gear?

If you are referring to wording " Easy access ball differential" by the picture of a gear diff HERE, I would say it's a typo as it clearly shows a gear diff in all the pictures.

Yeah that's the bit I meant and I assumed the same as you surely it's a gear diff

Yep, apparently there will be a stand up 3-gear that allows the shocks to be on the front of the wishbones - so probably must have the new slipper.

From RC Tech
There are 3 new gear boxes for the b6.1 (3-gear stand up, Laydown, and Layback). All of them have a quick change diff and all of them allow the shocks to be ran on the front.

I don't think anyone will really know until B6.1D cars hit a wet astro track but I am fairly confident they will be THE hot ticket with the layback gearbox.

Recently I've spent many cold & wet hours at Kidderminster with grip levels less than that of ice on the areas in front of the rostrum and against laptiming the laydown is definitely quicker and realative consistency is the same for both.
Only thing I'm doing is trying to get the weight as far back as possible without adding additional weight to the car. Based on this being able to move both the motor and battery back 8-10mm (estimated from images) will be a huge benefit.

Now I've typed that watch us have the driest and warmest season on record :)

So who's pre ordered what then?

I’ve preordered one, my lads having my b6..that’s what got me the ok from the Mrs lol
Any date yet?

I've ordered a b6.1d , never run AE before so hope it's a good choice

At last you are doing the right thing Ian....! 👍👏....best decision you've made..😂.......and if , for any reason you don't like it, you can sell it on to me..!

Can anyone confirm the B 6.1 D comes with a ball diff ? thanks

Yes according to ae site info

Won't be long now :thumbsup:

2 weeks :lol::lol:

Do we think there will be a new 4wd car coming too?

Hi,

Should be in stock with shops soon.

Some on the way to me, should be here Friday.

MiCk B. :-)

Hoping mine will be with me tomorrow.

Got new kit
 

Kit looks mint , anyone got any tips for carpet set up or should I follow kit ??

Built my b6.1 over the weekend, everything seems to be a snug fit compared to the b6 much less initial slop :D

So , setups for the b6.1.

The kit setup seems quite soft to me, certainly compared the to b6.

Has anyone run theirs on dry Astro yet (probably not considering the weather)

What changes have you made from kit setup and why?

It is the 2x1.8 rear pistons that cause that feeling.

Ran a full day (nearly 8 hours) at Kidderminster with mine.

B6.1D ... so much forward drive it's silly, on a par if not slightly better than my B6D stand up, corner speed nearly as quick as the laydown in the same car.
Drying track stopped play.

B6.1 .. even on the kit setup it was obvious immediately that the car was more than the sum of the parts.

Has a lot more steering than the B6 and generates far more forward drive too.

By the end of the day I had a really sweet handling car that was easy to drive and quick (had an F1 driver there for some of the day so had a pace setter).

Changes from the kit B6.1 setup (other than building it with hard arms and alloy front bulkhead)

Front bar from blue to white
Front oil to 37.5wt

Wheelbase to medium on rear arms
Removed rear ARB
Rear shocks changed to 27.5wt/2x1.7/grey V2 spring

Added 35g under the LCG lipo I was using, total weight of car 1555g.

Tried lots of other stuff but kept going back to the kit setup for reference and like the longer links.

If the grip wasn't quite so high I'd be tempted to go back to the more customary set middle hole in front bulkhead and middle hole on the rear camber plate.

I strongly recommend starting with the kit setup and tuning from there, if you bolt on your old B6 setup you might miss some of the benefits of the new car ;)


As for the B6.1D I didn't get chance to change much as it dried really quickly.
At Coventry this weekend Dave Searl ran his B6.1D to great effect, kit setup other than shocks on the back & softening oil 1 step in the pouring ran.

I had a conversation yesterday with someone about the 1.8 pistols and why they came with that. His reasoning was the molded 1.7 pistols had a lot of slop in the shock body that fluid flowed around the piston and now they are machined and a better fit they have opened the hole by .1 to give it the same feel

Hi Roger,
Can I confirm your link position on the front caster block on the B6.1?
In the manual, the setup at the back says outer hole, but in the assembly instructions, they use the inner hole on the caster block (ALA B6).
Which one did you use?

Thanks
Mark

Stand up gearbox for 6.1
 

I see there's a stand-up gearbox AS91788 is there anything else needed to fit it to a 6.1D as I see the kit came with a spur gear cover for it? Just asking because run yesterday on wet slimy astro it was terrible fitted old three Gear stand up box instantly 4 seconds quicker massive difference

My thinking is there will be a conversion kit for thw standup as the 6.1 also came with gear cover and waterfall

Also need motor plate 91794, top shaft 91798 and possibly idler gear 91717.

What’s the benefit of using the 4mm steering block over the 3mm steering block
