Subject: Re: [BugHLG] Airfoil Options, Name & Stringing.
I had an old 2 meter glider called the Easy Breezy back in the 80’s and it used 2 balsa strips between the leading edge and the main spar. There were used as both turbulators and for strength. The plane flew great and I could usually outfly Gentle Lady’s and Olympic II’s regularly. So I guess it was beneficial.

What ill do is include a few options of the airfoil. Like John said, the original Selig 7014, AG37 & maybe the Drela foils. Optional half ribs will be a standard on all the wing plans. (Doesn't hurt to include them and it doesnt change spacing of the current ribs, they just fit in between) As for names, I had a few and mayfly was one that i was quite keen on too, but bugger buggered have quite a Kiwi (New Zealand) catch to them as it is a very common saying here. So keep em names coming! One thought i had for keeping the airfoil in shape could be stringing the leading edge? I saw this method used by an old guy here in NZ and he said it was less weight than sheeting the leading edge and the strength from it was great. It also allowed him to space the ribs out more without the sag of the tissue in-between. Dave Robelen used an interesting method with a tubulator for his micro models to generate lift. While we wont be throwing a square length or balsa onto the top of the ribs i just brought this up to suggest that the tiny bumps produced by the stringing the leading edge might not be too harmful? Thoughts anyone. I wont include this at all in the plans it was just an interesting thought and i will make a wing up like that to test it out & let you all no how it goes...
