Mel,
Please, Please ANY trainer pics you have, I'd love to see. That goes for anyone else who reads this thread. I have collected over 500 pics of Army trainers, but you can never have too many!
Aaron,
I e-mailed you the other day, I guess you didn't get it. PM me if you get a chance. As for the differences between A, B and C model Hueys:
Alpha: short rotor mast, blade counterweights face down not up, different weights on the stabilizer bar, ammo chute exited forward fuselage instead of the rear like B and C models. I think the rotor blades had a smaller chord as well (maybe 15 inches), right handed fuel filler, nose mounted pitot, narrow chord symmetrical stabs, narrow tail.
B model: Same as Alpha except: taller rotor mast with blade counterwieghts on top of blade grips, newer style stabilizer bar, ammo chute exits the rear of the cabin (more forward on the left than the right), blade chord is 21 inches
C model: Same as Bravo except: different rotorhead (540 in C vs. 204 in B), blade chord increased to 27 inches, left handed fuel filler, roof mounted pitot, wide chord assymetrical stabs, wider tail cambered 5 degrees, support bar for the M156 universal weapons mount.
There are other differences that were variable, but those are the main structural ones. The 1/72 Italeri kits can be made into a nice B, but to make a Charlie model you'd need a 540 rotor. Cobra company makes one or you could steal one from a AH-1G cobra as they are virtually indentical (except that the cobra lacks the stabilizer bar on top). Making an Alpha just means some scratchbuilding, but making ANY accurate US Army bird from the Italeri kits will require some scratchbuilding. I hope that helps.
