You are making quick progress on this one Roman, well done.

and another thing - I assume there is something with the wheel base in that kit as original data says 86 links per side and Trumpeter has 84 in the manual. Well, Trumpeter's tracks are out of proper size but look here. When using metal tracks with correct size I got a lot of sag with 86 links and 84 would not be sufficient here.

There is no way to adjust idler position without modifications, so I will keep it as it is, or maybe skip one lightweight split track to avoid that sag.]

Trumpeter have departed from their earlier link-and-length tracks, in favor of individual link tracks. No vinyl tracks are included. The tracks depict the split-link tracks without a guide 'bump' on the split links, appropriate for an SU-152. However, the kit tracks scale out to 700mm wide, whereas all vehicles based on the KV-1S were fitted at the factory with 650mm tracks, except for a few early production examples with 608mm tracks. For accuracy, you should replace the tracks with aftermarket items.

Well you have more data than we do, it was just an impression given the photos of your build you put up. Have you done the comparison with the outer face of roadwheel and outer part of the track? Does the width check out?

And I just wanted to give a constructive remark, Me I'm more interested in constructive remarks on my builds than the "WOW it's great!!!!" style of "feedback", but to each his own (just saying that because you sound pissed off);

Also this vehicle has been a pet subject of mine for years. I have the kit and some reference at home but I'm on holiday right now.

Cheers,

Christophe

BTW, the problem with the Trumpeter split links is well-known:
