I did not buy the Dora but in multiplier I found it easy to out turn under normal conditions. The only time I had trouble was at high speeds say 270+ mph as a rough guess, or when he dropped flaps, but when I suspected this I took the fight into the vertical and has success that way. 190 rolls better, I expected this. The 51, at least on paper should turn better I think, as it has a lower wing loading, and I really don't think laminar flow is as bad as people say it terms of lift production as well. I have noticed many people quote only the tip airfoil section's CLmax value for those heated P-51 debates,(who am I to talk, I'm no expert, just suspicious).
In terms of vertical performance the Dora has a pretty significant advantage it seems. Even when he tried to keep turning with me they seemed to have much more vertical capability, I would even occasionally see him stall or drop a wing multiple times and he still had ample performance in the vertical.
I know I shouldn't talk tactics about a plane I have not flown yet but the Dora just seems like it should be kept fast, even if it can turn on part with a 51 why give up that advantage in vertical performance. I feel like it would be much more beneficial to Boom and Zoom or energy fight in it.
