Bug HLG

Hi John, I thought about mounting the horizontal stabilizer with screws or something, but didn't on this one. The vertical stab is slotted to mount on the fuse boom closer to the centerline, the horizontal stab is glued to the pylon, and the pylon glued to the boom. This was my first bug, and I built it with the cruciform tail. I haven't tried a v-tail bug. The v-tail might be lighter, but from what I've read, the cruciform is better for side arm launching: less stress imposed on the fuse, and straighter launches. -BC --- In BugHLG@y..., "John Gospodarek" <John.Gospodarek@i...> wrote: > Bob, did you make your tail detachable?
