You will need to make a production mold for those. > There's going to be a serious demand for them! Hey Bob, Thanks...yes, cool is good!. But I believe they will function somewhat better than Justin Kennedy's who claims enhanced performance...he sez he "delays the wall of drag most Europas hit at 130 kts. until 150 kts". Justin also notes, "Absolute cracking result. I predict you will be one of the fastest Europas. Not only that but in a shallow cruise decent you should reach Vne very, if not too, easily. Where and how to make the join is a tricky one. I sent you pictures of how we did it but it is quite arbitrary. We left a small amount of the under fairing attached to the flap which, as it curled down, served to stop the air spilling off the end of the flap in ground effect situations. The jury is still out on whether this is desirable or not. "When ours was test flown by Andy Draper at the factory we did not need the stall strips on the leading edge as a satisfactory buffet was experienced without them. Andy put this down to the wing roots so that is something to look out for. I hate these little plastic stall strips on the leading edge and was v. happy that we did not need them." (That may be an issue particular to the Classic) I'd love to see a set put on someone's plane which has recorded flight test #s just to see what they do. As for my mold, a local guy who used to do FG work at Boeing looked over my shoulder and recommended 4 layers bid tooling cloth which is 8/9 oz. w/ a pretty tight weave...he's made many production molds from FG, but we'll see. You have GOT to be nearing First Flight!...I do envy you!
