Bug HLG

Thanks for the input. Im not sure if I will build the cruciform this time or not. I am working on a 2nd fuse but I have not had mush time. I have used a 1/8th CF tube for the boom. The V-Tail may work better than the cruciform on that size of boom. I have the V-Tail already cut so I may have already have made the choice. Thanks again, and I'm sure I will try the cruciform sometime. --- In BugHLG@y..., "bob_chiang2" <rhc3@c...> wrote: > Hi John, > > I thought about mounting the horizontal stabilizer with screws or > something, but didn't on this one.
