I have decided to stick to Schumacher for 12th scale, despite the missing F1 chassis, so that is good to hear.

In Atom 2 - what happened to damping the front? System like Asso 12L when I left the sport 1985...

It is the same as the damping on 90% of current 12th LMP cars. It works and keeps the car simple to work on.

You are right - and of course I am provoking a bit ;-)

Lets analyse the info´s. The exploded diagram is available at racing-cars.com.
I like the hard-coated kingpin U7880, although to my knowledge, DLC coating would be even bettter frictionwise.
The ball joint U7881 we find in former designs, like the Supastox pivot of rear pod and current Eclipse2 front axle carrier mount. This part did occasionally break out of the press fit in its mounting hole. After learning that, in all my cars I secure them in with superglue.
This ball joint was never freee of play and cannot be adjusted, but the distance of upper and lower beams U7892 U7892 may put the wobble in the usual tolerance, which seems to be class standard.
I am still waiting on higher precision front wheel guiding. It may improve the performance. (In a real car, if there is any play, something is broken or worn out and you must repair)
The play in the ball joint bore for axle + damping fluid will again provide a damping function. There is no reason, the damping fluid will stay in these quite short space, resulting in frequent maintenance. I found the current eclipse 2/Atom solution more elegant - you can re-feed damping oil from the top mounting holes of the kingpins.
The solid mount of the upper beam will increase stability, but add a little weight.
In the back, finally adjustable play free side links U7872 (like many competitors) and a new pivot with also adustable play. This promises improved function = maybe improving performance.

Certainly a good car! Schumacher doesn´t release cars without competition testing.

Best regards, Erhard

So can I just install my Eclipse 2 rear hubs/axle on new Atom 2 and have a new "LMP" class 12th scale (convert 12th GT to standard 12th)?

Do you have any experience with the Eclipse 2 in the GT12 body? The GT12 body's downfors are clearly smaller than the C12's. For

I'm asking if i can convert the new Atom to a standard 12th scale chassis in order to shortcut the wait for the new Eclipse. I need a new 12th.

GT12 is an up and coming class it seems...is the steel chassis competent for that class? I have a small indoor track I'd like to toy around with

You could, but you'll have a very heavy LMP. The Atom 2 has a steel chassis as it is designed specifically for GT12 (original UK type GT12) with a weight limit of 950g, so just the chassis plate weighs over 200g.

I think, if you have no motor limit and therefore compensate the heavy weight, it is worth a try. The low center of gravity is a significant benefit.
The rear axle can be transferred. In fact, only the hub carriers differ.
On the front, the story is different, The GT12 have smaller front width too. I am not sure how to adapt front width. Is it just the wheels? I dont think so, but I don´t know.
I think the Atom 2 is showing a bad thing. GT12 was designed to be a robust class for a budget option in Racing. Now - the components are expensive again and identical too LMP. But the cars are no more robust to the same extent. Quite the contrary - the parts are more stressed due to the great weight difference. This is damaging the good idea and spirt of GT12.

Interesting and still tempting.

I completely disagree about the Atom 2 not being robust. It is probably the strongest GT12 car that has ever been released. I know how much extreme testing Schumacher put in to make sure that the car is not easy to break.

OK, what about the carbon diff-axle? We broke a few in the 20% lighter Eclipses. Also the improved ones. Never broke a steel axis in Supastox. The rear axis ball bearing - same. (compare to supastox Ball Bearings)...
Front axle ? OK might be more robust, than Eclipse.
But I do not only want to complain. Overall the cars are competitive, robust and easy to work on. The price to value ratio is excellent.

Anyways, I am looking forward to the Eclipse 3 as the Atom 2 does not fit into our weird German GT class with 800g weight limit. (basically we run pan cars with GT shell, not even tyres need to be different).

Maybe an Atom 2 with lighter chassis (-150g!) would be a solution here. Should be doable with carbon instead of steel, as an option part.

Any idea, when the Eclipse 3 will be released?

Best regards, Erhard

Maybe you ought to look at the Atom 2 more closely. You haven't even noticed that it has a steel axle. If you look you will realise how much thought has gone into it.

My fault! Well, the exploded view is showing a black (carbon) axle, but looking closer, Kit axle has a different number and in spare part list appears as steel-axle.
