Hello Scooty, Thanks for the complament; I used the Parma Dual Tip Detail Pen, it seems to hold up better than a Scripto Fine Black permanant ink pen. I had to let it sit over night, but now I can use glass cleaner and it doesn't wipe off. I do have to go over areas when fuel sets on it at the field, but it's still visible so I just go over it and let it dry.
The maiden flight was out-standing!

I only had to click ailerons 2 clicks left and she was flying perfect. This is by far the best Mustang I've flown in the 7 years flying R/C, it has Zero bad habbits, I can crawl to land or fly it to the ground and chop the throttle; it's a very forgiving wing design. She also does some wonderful aerobatics. I'm pleased with Great Planes, it took me about a month to complete; the maiden flight was flawless. I posted pictures of her flying and the tail end of the landing. I'm not sure where they are now, I suppose you could look and see if you can find them. Take it easy, starcop
