Toshi, Just wanted to stop in and say that I really enjoy your builds. You, sir, show the patience of a gentleman, as my grandfather used to say to me when I was a kid. And I'll be watching this one with much interest, this kit is very high up on my wish list. Another note about the P-61, one of my favorite planes of all time. The nose cones were designed, if I'm not mistaken, to not be painted because the paint could degrade the radar set's ability to work properly. You have to remember, this was all new technology back then. I remember reading pilot's accounts of flying the -61 in combat, where they would say, "weapon bent"--when it was raining and the nose got wet, it could be enough to make the radar not work at all! Here's an older article from a magazine about a Black Widow that ended up shooting down a B-29--intentionally. Crew bailed out and they got to splash it. Cant wait to see how your bird finishes up, that cockpit and the IP are awesome!
