Since I'm hating on the Hurricane series (by misusing the poor things by doing really stupid things with them, like hanging out behind massed bombers at 50-100 m), I've discovered a few other bugs.
It appears that the armor that surrounded the reserve fuel tank (the one ahead of the cockpit, behind the engine) and the firewall isn't modeled, or else are modeled in a way such that the armor isn't flush with the fuselage.
The effect is that rifle caliber bullets penetrating from dead ahead, penetrating the fuselage just behind the engine, penetrate the engine firewall and the reserve fuel tank (probably empty since I was flying with 50% fuel) to seriously wound the pilot.
The problem is that there should be about 1/4" (6 mm) of armor plate over the top half of the firewall, plus at least four layers of aluminum (2 for the firewall, 2 for the tank) and possibly more layers of armor that surround the reserve fuel tank that should slow down or stop even an AP 7.62 mm bullet fired from 100+ meters.
Cutaway view that shows what I'm talking about here (assuming bullets penetrate about 25-50 cm ahead of the filler cap and penetrate through the instrument panel):

This website gives really nice illustrations of what the armor and firewall look like and how they should be mounted:

As another minor issue, it appears that while hits to the leading edge of the inboard wing will puncture the oil tank mounted there, the black smoke "oil leak" effect only emerges from just behind the oil cooler on the plane's belly.
It also seems to be impossible to get a coolant leak effect (white "smoke"), despite the fact that the coolant radiator and oil radiator seem to have shared the same housing.
