I think you meant some computerized parts like FCS, HUD, RWR, radar, MFDs, DL because warbirds also have electrical systems, avionics, hydraulics, engine management stuff (air/mixture/oil/water/cooling), gear&suspention, airfoils, canopy animations, FM, DM, cockpit/external model, IR signature, textures/liveries, weapons integration... all this has to be modelled and coded and it doesn't seem that much less than modern jets. Maybe it's possible in 2 years but counting on it does not make sense because we can see how it ends in practice. Anyone seen F4U lately?
