Zap, I and many others, have been testing the effects of radiator drag in the game since the latest patch release. Some of the results of the tests are in plain sight all over the forum. If you're suggesting that there is an actual game bug whereby the radiator drag effects are nullified by following this procedure, then by all means test it yourself and report your results.

However, I can tell you now, that the amount of surface area producing drag from the radiator shutters, programmed into the RAF fighters' Engine Modelling, was Doubled from v1.07 to v1.08. It was already 50% greater than the radiator shutter drag surface area plus oil cooler drag surface area modelled into the Bf109's Engine Modelling. This means that this surface area for drag calculation purposes in the RAF fighters is now Triple, three times, 300% greater, than that modelled in the Bf109s.

After extensive testing on a public server with temps effects off, then further extensive testing on a public server with temp effects on, i.e. ATAG server 2 and ATAG server 1 respectively, the workaround with 50% rad seen in the video, (if you even watched the video or followed the link) is the result.

In addition to the excessive radiator drag virtually nullifying any increase in rpm and/or increasing of boost setting, the relationship between adequate airspeed and engine cooling is dramatically more critical in the RAF fighters than in the 109s.

This information (in much greater detail) has already been communicated to both Luthier directly, and their FM programmer via BlackSix directly.

The problems surrounding incorrect mixture modelling also highlighted in the link I gave have also been communicated directly by both me and IvanK.

I would've explained this earlier, but I'm a one fingered typist, and posting stuff of this length more than once gets on my wick a bit. Please read the thread I linked in more detail.

Thanks Mate.
