There were plans for a F-117 several years ago in RCM... one guy in our club built it and it crashed on the first flight. It had a unique (strange) feature in that it had some type of elevator thing in the back. The article even said that this necessary to get it to fly. I hope you have better luck because you are doing a great job building this unique aircraft. Good Luck, I'll be checking back to see how thing's are going.
