I still didn't like the look of that Seasprite, the nose just looks so big. So I went and scaled in a three view and it is quite a bit out of scale. Airframe is just too big plus the nose out of shape. I think the problem with helos is there is no simple measure like length because this often includes the rotars which often aren't drawn at full length. But using the US Navy's SH-2F Standard Aircraft Charcteristics form (I've added a link on refernces to a page with lots of these) I've found a fuselage length from nose to aft of tail boom but not including rotors of 40.5 feet.
I've started to draw a new LAMPS I Seapsrite but am only from the tail to the fuselage and will include some of the early versions, top view and a tail down landed view, plus the later SH-2Gs. At the top of my aircraft to do list but like Timothy won't be quick because of exams. Though I like to draw as a study break.
