Bruce,

Thanks to you (and all who have participated here---I hope it goes on).

My problem in understanding has been a natural affinity for relatively high----well let's call it moderately high aspect ratio (vs. sailplanes)---- designs (that preference also identifies my age group). These designs are used in fully aerobatic models which are capable of the complete pattern schedule though they are NOT currently competitive--nor intended to be--with the two meter planes. (they sure fly prettier though)

I just don't feel that I had an understanding---certainly not a good understanding--- of the adverse affects of the higher aspect ratio designs. I have a limited understanding of the effects of the lower Reynolds numbers as chord is a multiplier but I hadn't put it all together properly . This exercise has certainly helped.

I do not feel we are at the bottom or end of the useful information to be gleaned here so I sincerely (perhaps selfishly) hope that the thread will continue for a period.
