In high gear it climbs around 40°, in the low gear it can crawl up to 53° slopes, sideways it holds up to 44°.

    Milan, many thanks for your efforts! I think proper drivetrain is great, however, the lack of central diff winds up the transmission and slows the vehicle  - so my question is whether you introduced Ackermann geometry to compensate negative effect?

      I also built it, and found this was a problem. Not much you can do with just the pieces from 42099, although if you had a spare differential and a little patience I'm sure you could make a space to fit it.
