That looks very cool! That's my all time favorite F-1 car---total innovation within the existing rules!! Of course, they legislated it out of legality!!

I continued to prepare the car for its first outing.

Installing the electronics is always a challenge. I want to have short black cables, hidden from looks. But that isn‘t easy with formula cars. I decided to do an arrangement with the esc behind the motor. This way five of the six cables from the esc can be quite short without interfering with the pod movement. The cable to the receiver is long therefore. The receiver sits on the front left and the servo between the front tires. This leaves an awkward space in front of the battery. Two reasons lead to this decision:
1. Attached with tape like Tamiya recommends it, makes the servo move under load. The front of the chassis is too narrow to attach the servo properly with mounts. The front suspension plate is wide enough to do it.
2. The angle of the steering links is quite extreme in the recommenced position. Even with the small compression travel of this king pin assembly, the angle of the tire was changed a lot. With the servo sitting on top of the front plate and a little upwards shimming, I could install the servoarm downwards and the links underneath the steering arm.

Some tuning parts were also added. I installed the RM01 servo mounts, F104 v2 carbon pod plate (for the wing), aluminium side spring holder, Tamiyas servo screws, the aluminium servo arm and endplate, blue steering turnbuckles, some more blue screws and a carbon rear axle.






I am also already dreaming of an independent damper style front suspension... Double A-arms, four damper... I checked for 1/12 front axles, but the costs would be extremely high. I will make a decision once the first day of running came to an end

Some more pictures of the car (I love the look!):

Gorgeous! One of my favorite Tamiya's from back in the day. Nice job on making the body sit correctly.

I really like the direction this Mistral is going. Very easy to adjust the set up geometry.

Two questions:
Was it too expensive to continue the simple adjustability at the rear by using shims instead of the plastic axle inserts?

Did you test top decks to see if a stiffer setup helped?

About the last part.
topdeck are interesting but they can lead toward tweak, if you (like me...) make some extra not necessary mistakes...
To mimic the topdeck effect, but w/o taking away torsion, we can use a turnbuckle between the 2 highlighted points.

Same servo fixing point, can be used if you want to use a long connecting rod for the shock absorber



Then...
I assume you ask about the rear axle, which relay on "old school" eccentric. If I understand well your question...


It's a common solution in our old Mistral, in our pancar and in the new Mistral 2.0.
Held quite well hot motors like the one used in Europe from pancar crazy fast guy....
it works...

No pivot ball... that's a thing.

yeah, I know, courtesy of Achim Schultz (fmr. Porsche chassis Engineer) on his 1:12 Ascari, which became the Hatzenbach Pro10 monsters, then the RCdevil pan cars.

Its always refreshing to see something different especially with the rear multi-link used on the Mistral 2.
What is the benefit over a typical rear pivot?

Also looking at the Facebook page, there are multiple holes for mounting the tie rods for the rear link.
Can anyone explain what the effect will be and when you would use the different mounting points?

Cheers

I believe this is the pic you refer to:


Roughly, a conventional pivot roll center is about B1.
Lower you go, more mechanical grip you can get.

When you want to play with roll center? when you to optimize the rear grip, for instance... aka trying to get the most out of a tire...

I forgot almost, that the VIP car from Tobias W. runs a similar setup in Pro10 and Euro GT. They are very successful in the RClemans Series, so the Fenix F1 should do quite well.

Here a pic of the Hatzenbach A12...

Basically... Mistral 2.0 take his shape from out G56 Pancar:


V-link is definitely interesting as is giving a wide range of setup. I never was 100% happy with the feeling I've with the Volante we use at ETS, so I start to look for some extra tuning options.
G56 backbone is clearly visible in Mistral 2-0
