The f8f differs in as much as it has a different cowl , flaps and a larger canopy. Pretty much like the real thing , the rear bare has slightly shorter wings too . I like them both and in the world of models its upto us modellers to use our modelling skills and improve them after all they have done most of the work . I enjoyed mine , it caught me out on finals but thats pilot error and for that Im all the better for it .
