Does anyone know now close we are to seeing a CH-53 addon ?I know some have considered it before, and now with animated rear doors possible it would be fantastic. The CH-53 is a superb helicopter - much more agile and faster than what most realize. It also is still a major workhorse for the US navy/marines. I wish there were some good O2 modeling tutorials - most inform re; getting a ready model into OFP.
