I guess it was a lousy NATS for Crescendos. My Class A Nos version stalled off the top of the climb on the first flight and stalled all the way down, which it does from time to time. I’m beginning to think the leading edge is too pointy. I am pretty sure on the plan that I have it shows the bottom on the wing completely flat, but I was looking at the three-view in the Zaic Yearbook last night and it showed the leading edge with a fair bit of upsweep or Phillips entry. So this winter I plan to build a new wing with that and a few other changes. Denny, what does the leading edge on your model look like?
