Dennis Bassano the president of NALSA asked me to take over the Nalsa web site . Instead I made a new yahoo web site because thats what I know and I like the...
Hi John, Great picture of your boat on the homepage. The paint job on the wing looks great. Sounds like everything worked out quite well after you got the bugs...
Later on I plan on building 2 new identical WD 40 boats. (Wing Development 40 sq. ft.). I will build the boats to be lab rats. I'm going for the original...
... I applaud your building of two near-identical yachts to do two-boat testing, with one as the baseline. However, I think this may be an expensive way to...
Tom, I Have a son and a nephew that are wanting to sail small wings really bad. The boats were in the planning anyway. I just thought it would be fun to mix up...
... There are lots of ways to get the coordinates. You had to have patterns for the ribs when you made your wing, right? Add the skin thickness to those, and...
Tom, Can Javafoil handle slotted flap airfoils? How about double slotted? While following leads on an Internet search a few weeks ago I stumbled upon a very...
Hi John, Excellent video!! Very exciting to watch and listen to. If I hadn't already built a wing, that would have inclined me to do so. I noticed you used a...
Kevin, I designed my flap controls to have the sweet spot at 22 degrees flap angle . Every wing will be different depending on where the pivot point is located...
... Yes, to both, I believe. I've not used it extensively, so I've not tried double-slotted myself. ... Read further down in the thread. You'll come to a...
Hi John, Thanks for the detailed flap explanation. I have found myself in the 25 degree slot most of the time. It seems to have the most power taking off. Once...

... That's too coarse a criteria. The leading edge really needs to be designed with something like Xfoil for the angle of attack/lift range. The resulting...

Great video John. It amazing how spread out we are after a half a lap. Did Alan spin out on the first lap leward mark? Is that why Bill was ahead on the...
Keith, Yes Allan spun on the first lap . I think he came into the mark too fast and steep of an angle. The big wingmast/sail combo's are hard to shut off . Not...
-John: As a competitive, well at least often-competing, DN sailor, let me offer a few words from experience: 1. DN Cost. Building a DN hull is cheap, with...
Ken, You must have been reading my mind. I was going to contact a DN er in the racing loop to ask them what they would recommend if they were contemplating...
... Have you checked Sarns prices lately!? You might be safer just quoting the boat w/o the runner hardware. I just added it up: front chock, bearing, rear...
Wow! thats a bit more than I thought. I'll keep track of what I spend to make these boats . I'm optimistic that they are not very expensive to build....
