Game Hurricane is 534 lbs overweight

It doesn't matter so much because how the FM is set up. The basic performance data seems to be set in stone (speed, climb, turn), and the engine just works out the results for different speeds/angles of attack/altitudes. More weight just not effects the raw performance so much as in real life, though it may well effect the handling/behaviour.

For example, since power and max speed are set, the engine may work out the acceleration from this, for which it also takes account weight. In the end, acceleration for example may be less due to increased weight, even though the plane reaches the same speed and turns just as well. OTOH it may well dive better than it should due to increased cross sectional densitity.

In short the effects are secondary, not primary.

That logic indeed applies to Spitfire and 109 as well, and so it does to all other planes. If they aren't overweight or less overweight, they are simply not done as wrongly.

That's not quite right. Of course it is possible to reach correct performance with totally wrong input numbers in game, but once you have your parameters set, and then change weight, there'll be the associated loss in performance just like it would be in real life. But be this as it may, imo a simulation game should have both, input and output correct. Otherwise the term simulation is just an empty phrase. Proper weights are one of the foundations for this.

Like I've said before, the FM of the Hurricane as listed in that other topic is essentially the same which was used in il-2 1946. Same fundamental flaws. It's a nasty surprise it was carried over 1:1.
