Nice...However done it for real at Spadeadam (though the peice of kit I worked on is not done on this sim, and in real life its a multi operator job to operate any of those Russian systems). I love to see somebody do a Bloodhound Mk 2 one (The Swiss still have a working LCP Mk 2 trainer at their Bloodhound Musuem at Gubel, which they use to show the public how engagements were carried out, plus they declassified all of the Air Publications (they used the same books as the RAF) including the EC Handbook on the day the system was phased out and kept a copy of all of them at the museum).
