Blade profile
Hi Sverre,
have attached another picture of the ends of a couple of blades. It's not critical but I sort of round the ends off.
Don't worry about 50 or 60 yrs to get off the ground. I have gyros here in Florida that last winter would get off the ground in about 5 ft with a 5 mph wind. Now, at 98 degrees and high humidity, I'm lucky just to get off the ground.
Phil
