The old WOP Spitfire Mk1 and BF109E, with all the A2A upgrades, seem to work well enough in P3Dv4 (with the usual lack of
VC click sounds), and I think look good for their age. However, these were upgraded to FSX standards pretty thoroughly.
I haven't tried porting over the WOP Zero to v4. As I recall, the WOP Zero never received the full FSX upgrade treatment,
it was only upgraded just enough to run in FSX.
