What's "good" and "bad" is something really subjective. It depends what you want, good racing chassis can be too fragile, which means bad for bashing, bashing chassis might be too heavy and slow for serious racing. So really bad chassis is the one which just won't work for you from whatever reason. Really bad chassis is fragile, heavy, non reliable, non adjustable and without spare parts available.

http://www.rc-tabor.com/Forum/ This one is only active I have found. RC forums in CZ are dead nowadays, most of people migrated to facebook. You can try local RC rally groups on fcb (brno, tabor, safaricup etc.), they might help you.

What about DF01/TA01/TA02? They can be built to different widths and wheelbases using different combinations of chassis and arms. For example Cayenne DF01 is 200mm width and 280mm wheelbase

Hello, I just registered week ago and now I noticed your topic Skoda shells in the past were made by Airdesign. It was just some sort of minor bussines, since their main bussines is acessory for real cars. Their bodies disappeared years ago and it's uncertain if they ever appear again. Now some limited amounts of Skoda bodies are made by local clubs, but it's mostly recent Fabia variant, not 1.gen WRC.

Reversible arms work well for rally. Maybe better than XV arms. But you have to grind fronts around C-hub a little to allow more than 15mm droop.

If you have issues sourcing 0.6, you can use 42p. Do not use 48p, that's equivalent of 0.53 metric, so it won't work.
