G'day John
Not sure how to attach files using the pprune email. Here's a copy of the

Mad Scientist, given that 140 KIAS at sea level is only a shade over M0.21 would mach no. effects be significant? I don't know anything about the variation of stall speed with mach no. - could you expand a bit?
Cheers
Rob.
