Also the cowl-spinner interface is shaped incorrectly on the sig.
We flew one of the new sig P-51's last week on a breezy day and i was surprised at the lack of consistant upwind perfomance and presentation.
What i am saying is that I think it is possible to have too low of a wing loading for and scale warbird.
This results in excessive sport type performance of the aircraft.
Althought a light wing loading will result in a aircraft that is more acceptable to sport flyers it also results in a aircraft that lacks scale warbird type of in air presentation. I prefer more scale like performance and presentation.
