The tail incidence should be correct as the model was built to be 100% correct. If you look at all air to air pictures of all full size spitfires in flight they all fly with a slight down trim,,, we actually know paul bonhomme who flys mh434 and i have chatted in depth regarding the spitfires flying characteristics and one of the first things he pointed out was the need for down trim in level flight,,, I personally wouldn't alter anything. Just keep an eye on your trim settings. Depending on the engine weight and how much nose weight you like to fly with,,, the trim should be slightly on the downside,,, i think all models fly better slightly nose heavy and as a general rule of thumb the C/O/G should be a 1/3 back from the leading edge at the root,,, this should apply to all aircraft in the ww2 fighter range,,, Ive flown pretty much all variants of model spitfires and ww2 fighters in general and have found this theory to be true,,, no doubt others will argue.
