Bug HLG

Dan, I like the idea of the added strength so I built with the added rib on each side. I was going to adjust the tip height to allow for the added length, but forgot. I ended up with a lower angle but I haven't noticed any major differences. The angle is not all that much different. The wing is bigger and thus turns a little wider (but not all that much). It may be hard to find someone who has tried it both ways, and with different angles, so just give it a try and let us know. Good luck. --- In BugHLG@y..., "Dan" <danstrider@a...> wrote: > What is the consensus on how much dihedral to use for the extended > wing?
