This version of chassis remind me a lot the original C01AL, flex is much stiffer than the S2 and if I am not mistaken it was also using a longer wheelbase like the last A800.

I already taken the measurements to make a lowered P12X with the droop screw. I am still waiting the first version from Shapeways to see if I am on a good path.

Thanks again Oleg for the new chassis.
Can I dream of a 10th anniversary A700 rerelease with all the last goodies for 2021?

Racing is nice but bench racing can also be interesting!
Do you think it’s necessary to have High RC set up on your car
Is it that you try to less roll chassis

Hi OVA,

I don't have experience with long arms but the trend right now is to run high roll center to if I am not mistaken, regain some roll...for my initial setup I will try to transpose some setup sheets for the A800MMX.
I just want to see how high I can go especially in the rear...for me it's about 1.75mm with AT21ST-A balls.

Copying setup sheets is fine but ultimately it's my lap time and consistency that decide which setup change I made. Between you and me I have a bad tendency to only try to find the fastest lap time possible but habitually the car is difficult to drive

If I check my old A700 setup sheets on high grip with short arms I almost always run between -0.5mm (AT21s) and 0.5mm. I tried sometimes more but it's rare.

I am impatient to do some testing!

Hi
I hear you..
I remember back than ,some of the racer added shim under the gear box to get more clearance

I am out of town for a few weeks and I receive my Shapeways order...I am not able to bench race but can still annoy people on the forum

My girlfriend even open the box and take some pictures!

Files will be released and free once I confirm the fit is perfect.

I have made two swaybar height version of P12X one at 8mm and the other at 8.5mm. They are asymmetric (left and right) and have integrated P06.
A tentative of a thinner AM73-3 with countersunk holes...I am not really certain it will be rigid enough and I dont think the countersunk will be OK but for a few bucks it's worth a try.
And for my A12 I made new P06 version with no lip on one side and a height of 1.95mm so no need to shave them after installation just a little bit of CA glue. Usable also on the new A700 aluminum chassis.

I just need to be patient!

I think the countersink is fine as long as the square slot fit perfect c/t the gear box.. the flat screw only just secure the AM73-3 in place
what worries me is the is plastic is might crack when the motor take a hit

Default a700

I've been running A700 in VTA now for four years and they simply have the lowest amount of drivetrain friction. The least amount of built in "fade" for an 8 minute main. per notes above, I have two chassis identical in set up except for roll centers. On the high bite I like my high roll center car, less twitchy and easier to drive for that full 8 minutes.

if you are interested in buying these two chassis and photo parts noted, reach out $600 takes all.(SOLD)

I just return back from my out of town work trip and test fitted all the parts.

All the parts works I am just not able to make test in the field yet but for low stress parts I don't see any reason it will fail.
The only part I don't trust 100% is the AM73-3 it's really flimsy but once I screw it to the rest of the car I have a little bit more confidence in it. In the pictures you will see that I use 0.5mm shims on both motor mount screws...the reason is that since 2015 I run the motor mount 0.5mm lower (no AM69) so if you want to run the motor mount at original height dont install them. I really suggest to use mode 3 and 4 with this plastic part so you will still need to install 0.2mm shims as usual.

Don't put too much torque on any screws...

So anyone that want the STL files PM me they are free. The only condition is to don't make profit out of them.
BTW At Shapeways I use Multi Jet Fusion Plastic Gray to be able to see thin cracks if they appear but you may choose black.
Like I said I am not a machinist or engineer so take anything I make with a grain of salt.

I am really looking forward to test the car!

Question:
which pivot ball do you have and the thickness shim you have under the AT21 ?
Thanks

Hi OVA,

Maximum is 1.75mm with AT21ST-A balls that are 0.5mm lower...so 1.25 with regular AT21...so no crazy high roll center here.
Caps are regular P03 with OR14V o-rings.

I really need to put this car on a track and see what I need for roll center...I am already working on a revision of the part I want to push the swaybar about 3mm more in the middle of the car. This will probably help to have more clearance on top of the P03.
