Hello! Thank you for your kind words! Scalemates say this kit dates back to 1992 - if they wanted they could have gotten in touch by the real thing by then, but it's early. Plus the internet wasn't really operational by then...
It sure is a big chopper - it's comparable in size to the F-4 Phantom, that should give you an idea. It's a direct relative to the Mi-8 transport helicopter, and that can take a car onboard, so you get the idea.
Thanks for your comment and have a nice day
