I better be (good at covering) had about 30 planes to get the hang of it. Believe I finally got the hang of it at about number 28. Had most of my upbringing with Monokote, and if you can keep that from wrinkling, Ultracote and especially Solartex is almost EASY.
The triplane will have to wait a little while, am finishing up a glider called Houston Hawk, at the moment. Had built the wings 2 years ago, hated the fiberglass fuse that came with it, soo..finally decided to make a wooden one. Another week and it will be done. Than maybe will get to that triplane, although really like your F2B too.
If anyone is interested here's a link to the Hawk plane: http://www.rcgroups.com/forums/showthread.php?t=691892
