Thank you Stoney.. BTW your avatar is one of my most admired persons in our history..

In addition to what others have provided so far I'll give you these quotes:


Robert C.Curtis, American P-51 pilot:
 On two other occasions ME 109s got away from me because the P 51d could not stay with them in a high-speed dive. At 525-550 mph the plane would start to porpoise uncontrollably and had to be slowed to regain control. The P 51 was redlined at 505 mph, meaning that this speed should not be exceeded. But when chasing 109s or 190s in a dive from 25-26,000 it often was exceeded, if you wanted to keep up with those enemy planes. The P 51b, and c, could stay with those planes in a dive. The P 51d had a thicker wing and a bubble canopy which changed the airflow and brought on compressibility at lower speeds."

The Naca 45-100 wing was on the XP51, the P51-1, the P51A/B/C and P-51D/K - All the same wing with one difference when the D/K was developed - namely a longer root chord to accomodate the new main gear and door. Gene lednicer did a very nice VSAero simulation on the B/D and there is virtiually no difference in the drag, but the D canopy was BETTER than the B w/birdcage and Malcolm hood. The wing on the P-51H was the Naca 66-(1.8) 15.5 so it was thicker than the 14.8% 45-100


Thomas L. Hayes, Jr., American P-51 ace, 357th Fighter Group, 8 1/2 victories:
"Thomas L. Hayes, Jr. recalled diving after a fleeing Me-109G until both aircraft neared the sound barrier and their controls locked. Both pilots took measures to slow down, but to Hayes' astonishment, the Me-109 was the first to pull out of its dive. As he belatedly regained control of his Mustang, Hayes was grateful that the German pilot chose to quit while he was ahead and fly home instead of taking advantage of Hayes' momentary helplessness. Hayes also stated that while he saw several Fw-190s stall and even crash during dogfights, he never saw an Me-109 go out of control."

My farther Bert Marshall, Jr.and his wingmand Chuck Hauver 354FS/355FG saw on go out of control in a steep dive near Mulhausen on July 28th for my father's fourth acore. He was also shooting at it so the result remains somewhat inconclusive.[/b]

Thank you Brooke - I will 'spell check' my posts a little more carefully next time.

Nah, don't worry about anything like that.  AH has a spectrum of folks from quite knowledgeable folks to folks who will argue with you until the end of days and won't be convinced even if they are misunderstanding some aspect of aerodynamics and a spectrum of folks from polite to cranky and belligerant.

Just keep in mind that there are many people here who appreciate contributions from folks like you and hope that you enjoy and participate in AH.
