Thanks guys, The tail is hopefully going to get built this week! The undercarriage was bent to shape and will get welded up tomorrow. All my worries about lack of nose weight faded away when I put all that heavy wire in place. The wheels come forward in line with the front of the cowl. Thinking about it today, I might fabricate the wheel spats from fibreglass, rather than block balsa, cheating, I know, but so is using Oracover and a brushless motor!!!
As for the tail, I think a pair of HS65 MG servos inside the fin will be the way forward.
That tailplane half way up the fin is a nightmare for RC !!!!
