I flew my modified E Flite P-51D 1.5m yesterday in light to moderate winds and some turbulence aloft. The new mod of cutting down the vertical fin worked great, no difference in performance or strength to the tail area that I could see.
There are a number of possible early D model P-51s that maybe someone is considering doing a repaint and tail mod to look more like the real thing. For instance, I'm thinking of a top ace in the P-51, Henry Brown of the 355th FG, who flew an earlier D model without the fairing on the leading edge of the vertical fin. This plane model could certainly be converted to one of those planes, if anyone is of a mind to do so. Just sayin.'
