@zathros Many thanks for all the info . I'll refer back to it and digest it all a bit at a time. It's 30 years since I've done any electronics so I'm a wee bit rusty . @spaceagent-9 Thanks again Jim . As far as I know I'm the first to publish any card model photos of the Buran on the web. Searching for reference pics for Wolf 359 is getting kinda bizarre now - half the results are my own photos from this thread! lol I'm not posting any build pics of this next one as I've covered it in another thread - it's Jim's, now familiar, Klingon cruiser:- The command module pieces were too small for me to use to I used a tiny blob of blu tac instead. The damaged one will have the command module, left nacelle and part of the left 'wing' blown off. It's well on it's way and should be finished tomorrow.
