Majord, many thanks for taking the time to answer my query. The technical manuals have thus far eluded my ability to comprehend to the point of achieving much practical application. Too bad you weren’t the author as you definitely have a talent for translating Greek into very comprehensive terms. I shall follow your advice and take another look at CS’s flight manual. Perhaps it will make more sense to me on my next go at it? You’ve been a big help. Thanks again--- Ziggy
