Hi Pail, You may want to check out a wing design programme called Profili2...as it has a tab in which you can work out reynolds numbers based on wing chord and airspeed/altitude..it helped me understand this alot better than I did...Rgds...Laurie --- In BugHLG@yahoogroups.com, Tim Schuh <tim@...> wrote: > > On 3/5/2011 8:44 PM, Paul LaChance wrote: > > Thanks Marvin, > > > > I actually do not have the plans, so I am going to scratch build a glider very similar to the Bug.
