Hello mates
I've done some progres with my drawing - most because help from Frankiewizc - but it's not easy to find material about Projekt 20180 at all. Some details are very hard to identify properly on the few current photos available and the vessels propeller are very much unknown
My best guess is they are the types which can turn 360 degrees because it seems there isn't any rudder but there is some kind of base to mount such propels.
If anyone has knowledge or materials which can help me on, I will be much obliged
I've come some further (it's my second edit of this message) and made some quite progress. But I've got some "holes" in my material - as you can see - where photos haven't been enough sharp or the angel has been wrong. And the propulsion is still a secret to me
Now I've come a bit further. The drawing here is removed, and I've placed my current improved drawing in a new post reply
