Dan,
Its rough, especially since everything on the tailboom is raised. The main fuselage seams aren't too bad though. The upper one is along the catwalk door separation on the turtleback and then it extends along the tail rotor driveshaft covers to the vertical tail. You shouldn't really lose much detail along here. The engine nacelles are a bit of an issue, but again, they tried to break them along the access door panel line. The seam does need some cleanup, but it shouldn't be too bad. The only area that you should use extra caution to avoid removing rivet detail is the tailboom underside. My take on that was simple. If no one's gonna see it, I'm not worryin' about the friggin rivets!
I'm almost finished with "51A", which was the first Longbow I flew. Should have it finished this coming weekend!
