Wow... without even looking at the model too closely, I'm tempted to e-mail Nels and have the file pulled just for sheer stupidity of the description.
Problems with his statements -
1) The An-124-210 was never produced so there are no specs and no real world numbers to base anything off of, just the guesses made by Antonov and Air Foyle for the STSA proposal which lost out to the C-17.
2) The model clearly shows an An-124-100 (or 150) with the normal Ivenchko Progress powerplants and not the RB.211 that was proposed. The nacelles are totally different for the two engines.
Everything I see on that model screams that it's Tim Conrad's AN-124 model being foisted without credit.
