Speed graphs for Spitfire and Hurricane

When the Spitfire II was 30mph too fast the LW complained so much it was banned, suddenly there are few on the LW fighting the cause for the RAF types which run way too slow now.

Interesting what you say about coolant now causing engine failure - that's a big fix and will be interesting to see the behaviour.

I'm not say, the small difference is OK, I also want that the graphs become accurate. I'm just say, the difference isn't 60-80mph (as the IIa was).

Yesterday one of my mate notice this coolant leak, but need further testing - or ask Luthier the detailed change list...

One of you is talking 50mph and the other 50km/h.

Lack of 50 km/h is at only 6 1/2 lbs power settings for beta patch Hurricane but when you know that BOB Hurricane MK1 was flying with 100 Octan fuel at +12 lbs emergency power the difference - lack of speed would be 50 mph at the deck.

Hi Tom, I know that 1C has stated the IIa was 60 mph faster than the RL Spitfire IIa, but my tests to 10,000 feet (where the majority of ATAG combat takes place) seems to place it within 20 mph (too fast). Have you seen the chart(s) that 1C has used? IC has adjusted the RAF fighter FM's downwards accordingly and I'm frankly puzzled by this turn of events and the reasoning or logic behind it.

Hi. No, I didn't see the 1C measurement results, but i don't understand, B6 why would say this, if it's not true.
ps. Some kind of Clod-compare would be the best. Everyone would be happy if we can get accurate and detailed performance graphs.
