Hi All,
I'm working on my next set of blades. This time I laminated some ceder so as to have the stock wider at the root. I'm using Hugh Piggot's spreadsheet and sticking to the chord numbers all the way to station 3.
Anyway, I'm looking at profiles. I'm leaning to a NACA2412/ I'm a little bummed that I already cut the flat on the back according to the spreadsheet, I can see that I can't quite stick to the NACA2412 profile all the way to station 3, but it will make it to 4. Anyway, anyone know what profile Hugh uses? I poked around on his site but didn't see it. What profile are y'all using? Something with a perfectly flat underside would be cool. But I haven't gone so far with this set that I can't start another.
Thanks!
Jonathan
