I spent a lot of time working with the RAH-66. Much of it with simulation work. The cockpit and MEP was by far the most advanced for a rotorcraft. While I did not fly the Comanche I knew many of the Army aviators who did work the actual aircraft. It was a good flying bird, even with it being very overweight.
The Army did make the right decision to cancel the program. The funding from Comanche will now allow for ~300 ARH(Bell 407), ~300 LUH(BK 117), 40 JCA(C-27J), new CH-47F, new UH-60M, new ASE and other kit. While the money does not buy all of the airframes I mention, you can get an idea of how much money was tied into one program.
Before I get on a dissertation of the impact of Comanche on the US rotorcraft technology sector, I think buried somewhere on my hard drive at work, I have a three view of the EMD/LRIP aircraft configuration. If memory serves me, the most outstanding visible differences had to do with the canopy layout and the addition of increased air inlet size (immediately below the engine inlet) to provide more ambient air to the IR suppression.
Edit: found the three view for EMD/LRIP. Hope this is what you are looking for...
A few pics of the cancelled EMD phase Comanche. Anyone have more info? I know for a fact that a publicly released 3-view exists but I haven't been able to find it yet.
