Dave..........Porthole here........Have you been flying your F-117 ? I have been still sorting mine out, but I have it flying pretty good now. Had to keep adding weight to the tail, but have finally got it right. Flies decent and looks real good in the air. I had to add a yellow stripe to the top of each wing for visibility reasons. My eyes aren't what they used to be, so an all black plane at a distance can become a problem. Let me know how yours worked out.
