CP, thanks for your response. I’m sure you are in the ball park; at least it’s a much more informed estimate than I could come up with. Now that I think about it, the .010’s could peg out my Heath Thumb Tach at 25K.
The 90 second remark wasn’t due to the way it flew. In fact it was like on rails and had a fast, flat glide. But my eyes aren’t what they used to be and sometimes the turns were made on ‘blind’ faith[
]. Easy to momentarily loose it during part of the turn. That was the exciting part.
