Respect and very nice find.

The game Hurricane handles like a fricken whale and can't out-turn spitfire or 109. It is not nice natured either. Needs MAJOR attention please!!!

The extracted game files shows 427 liters or 94 gallons as max. fuel load, so your data card's figure of 97 gallons is not being used.

The TARE weight of the Hurricane IA Rotol with bullet proof windshield and armour plate used in the RAF test was 4982 lbs/2265 kgs, which is 744 lbs less than the TARE weight of the game aircraft which is listed as 2603 kgs/ 5726 lbs.

Scroll down for weights of 'overload' aircraft. (6750 lbs)

Also, real hurricane rotol takes 8 minutes to get to 17,000, in game it takes 12 minutes! the real hurricane in 12 minutes can get to 22,000 ft. Also the climb rate above 17,000 is shocking.

In addition, the dh5-20 is faster than the rotol to climb, which should be the complete opposite.

This is all totally unacceptable in my opinion.

I can't disagree with the perfomance issues. I can't see the weight of the pilot's seat armour and IFF included anywhere (73lbs) not that it would answer all the questions.

EDIT: IvanK, when I do my tests I adjust the fuel load to get the same weight as the historical data tests.

EDIT2: to avoid confusion I meant I can't see the pilot armour weight and IIF equipment in the Buzzsaw/game data. I'm sure it would have been in JtDs figures.

Here is the second weight summary for the Hurri report.

No, the Spitfire is all right, ours have armour plates modelled, which weighted about as much, the test you have shown simply does not have armor plates installed (which no Spitfire had prior to the end of May 1940). The so-called "armor plating over the tank" is in fact just a very slightly thicker aluminium plate over the fuel tank (its more like a deflector plate since it can really stop bullets unless they come in a shallow angle), but the aircraft lacks the pilot's back steel armor plates etc.

So the Spit weight is quite OK.

The Hurricane is well off, good spot.

97 gallons is the fuel tank capacity, of which 94 gallons are useable. Usually the 3 unusable gallons are included in the tare weight. 4982lbs is the weight of the aircraft without bullet proof windshield and armor. These items were not actually fitted, but the plane was ballasted instead and the extra weight is included in the service load.

Good work on this Buzzsaw. Note too that the Rotol propeller unit used on N3171 was heavier than the de H unit; the de H 2 speed unit weighed 345 lbs

For comparison tare weights are given here (Spitfire I w/de H unit 4,599lb, no armour or IFF):

Spitfire I w/Rotol 4,713 lbs a difference of 174 lbs:

With armour plating and IFF equipment fitted the standard de H propeller Spitfire I would have been slightly lighter than the Rotol equipped versions without armour and IFF, not forgetting the conversion to de H CS propeller, which would have added some weight to the propeller unit.

Very interesting. One point which might be worth considering is whether the real life weight includes a pilot. If not then the game weight would need to be a little heavier to allow for this although you would be unlikely to have a 700lb guy sat in the seat!

Just for reference - 1 gallon of British fuel weighed 7.2lb (Spitfire - The History)
