Something I learned from building an Allegro Lite..... I built 14 horizontal stabs trying to get one lighter than Drela's sanded solid balsa one. That includes bagged glass/balsa, covered balsa, built up and covered etc. The lightest one was a simple sanded balsa stab with a carbon strip and a light coat of dope. I suspect you'll find the same thing for the bug. Stick with a simple light balsa stab and you'll get the lightest. Maybe add a very light coat of dope to seal. Note the emphasis on light. If you don't have a gram scale next to your building board, your mileage may vary. Steve L.

The fin/rudder goes through some severe side forces during a SAL/Discus launch. If you look through the photos of Bugs on the group site, how many do you see with a fin/rudder with lightening holes? This is because lightening holes are also weakening holes. > I'm not saying that it's impossible to have a tail built with lightening holes that has the strength for SAL (early Blaster DLG's had CF built-up tails). It just won't be any lighter than the solid surface tail. > > John > > ________________________________ > From: Christopher Behm <cbbehm.lmbehm@...> > To: BugHLG@yahoogroups.com > Sent: Saturday, December 29, 2012 2:13 PM > Subject: Re: [BugHLG] Re: BUG DLG Modifications > > > > Aren't there some extremely light coverings available now?? > What are your recommendations for sealing the balsa from moisture?? > > Thank you DLR for your advice. > > R, > Chris > > --- On Fri, 12/28/12, gldrgidr <mailto:gldrgidr%40yahoo.com> wrote: > > From: gldrgidr <mailto:gldrgidr%40yahoo.com> > Subject: [BugHLG] Re: BUG DLG Modifications > To: mailto:BugHLG%40yahoogroups.com > Date: Friday, December 28, 2012, 8:59 PM > > > > From long expereince, holes and covering look better but weigh more than a light weight balsa solid surface uncovered.
