You've likely seen this. This is based on Stephen Chao's way awesome Pelican. I saw his model, and wanted one for my own. So after REALLY examining his photos, a lot of money, a gross amount of time experimenting, finding what works and what doesn't and then changing what I didn't like about his, I give you my version of the Pelican. The biggest change is that my version has the pilot and co-pilot sitting side by side. All four engines rotate, The back pops down for quick deployment, The canopy opens so you can put pilots in, even the doors to the cockpit open and close. I haven't sussed out how the front Landing gear folds up, so for now i have a place holder. Other than a bit of cosmetic stuff, it's pretty well done. This is the biggest MOC I've ever built, and it was a big pain in the heinie. I loved every moment of it.
Definitely one of the better lego pelicans i've seen. also one of the more unique paint schemes i've seen. Thumbs up on that. however, that forward-facing fin that's right behind the cockpit bothers me. I know what you were trying to do, but i'm afraid I don't know of a LEGO piece that will fill that role well. IMO,you should remove it, or possibly modify one, but it's still a great build.
