I was typing in the figures for the RV8 in my program when notis that 210mph
was 182 knots.

by the way, with all settings at standard it gave an optimum diameter of 72"
but there are many but's.

Jim,

Just to eliminate all errors, I guess you don't misstake knots with mph,
but
210 mph is 182,45 knots, what units is your ASI and GPS reading?

Good thinking, good question. Knots. :-)
