Cheers Curare - had a feeling that'd be a good answer.

One of my two airfoils is Bruce Tharpe's TLAR off his Four Star series, or at least a close relative. No-one's ever told me that a Four Star is boring to watch...

The other's NACA 00** - have it in CAD format, real easy to change the ** bit for thickness.

Amateur night still, but if % thickness has reduced, does that mean that flying speeds have gone up some? I got to a couple of pattern comps in England just before turnaround became the Big Thing and the speed some of those babies could hit on the display line was pretty staggering.

Low AR for a stiffer wing framework, but sharper taper on the wings to keep snap/spin departures within easy reach - sounds good.

Time for a new blank CAD file.

Thanks again
