a few notes:
the main rotor head you modeled is too flat. The -60 hub is actually quite big. I'd say about .7 Meters tall and a little over 1 meter long.
I can see that air intake would be pretty hard to model. it is an odd shape, it could probably be a little longer. The exhaust duct you modeled isnt bad. Just so you know, most of that exhaust duct is hollow, if you look at it from behind you can see almost a full meter in.
I saw on spot where the perportion was wrong, the area forward of the cargo door and aft of the gunner's window: there should be a piller there a bout a half meter long. The langing gear vertical strut goues all the way to the top of the cabin. Hover most of it is behind a fairing.
The 'red light' you have on the top of the aircraft isn't red. We call it the 'disco ball' it is a cylinder with many little sqaure mirrors.
The 'bump' on the front of the aircraft. That is actually just a color weather radar system MH-60's don't usually have those. Typically only Medevac and Search & Rescue birds. Most MH-60's do have the long refueling probe on the front.
Overall, I'd say you built a very fine model, and most people would not notice the little errors.
I still fix US Army helicopters,.. as a civilian contractor
I wish I could get you some better detailed close ups. However, cameras are not permitted on the compound. Security it pretty tight these days. I'm still looking for that box of old photos, there might be something useful there.
one more thing: I realize this model it not ment to be photo realisitic. If you ever feel like make one here's a tips:
HM-60's are not olive drab like the rest of the Army helicopters. They are almost black, I'd say a very very dark green.
Along the the length of the tail boom it reads UNITED STATES ARMY on both sides. Also, on the vertical stabilizer in the back below the tail rotor there is the 'tail number' for all -60's it reads like this: 97-26123 ,... okay, the first 2 digits is the years it was built. the 3rd and 4th (26) designates it as a Blackhawk,.. the last 3 are the serial number meaning, from the tail number I have above it was the 123rd Blackhawk to be built in 1997. There's a bit of useless trivia for ya!
The area behind the engines where the cabin section meets the tail boom (called the transition section) usually has black soot for about 2 meters behind the exhaust.
Military helicopters are dirty! They work for a living. On -60's you normally see oil stains around the front on the air inlets. There is a seal that loves to leak fron the engin gearbox. Normally it's the left hand side that leaks ,.. but sometimes both.
I hope this helps you! I'd be happy to answer any questions about any of the US Army helicopters, (short of compromising national security. LOL) I work on all of them.
When my LW skills improve, I plan on making some seriously realistic models. stay tuned!
