@Devs: Stop the Central nerfs - its enough

The fact is all the Merlin aircraft except the Spit IIA have a serious engine rumble issue that varies from type to type from as low as 7000 feet up to around 16,000ft. Throughout this band they are all power limited. You can transit this band with limited power to keep the rumbles at bay. The 109 suffers no such issue in this band. Its a fact of life in CLOD that has to be worked around. The fact that the RAF types can struggle up to a higher altitude than the 109 is being overstated .... who is going to use that capability to fight ? Agreed there is a global altitude issue in the FM/EM's it shouldnt be there but we are stuck with it.

As to Eng cooling its no a big deal in the RAF types any more. the last RC2 made some significant changes in this area. Engine cooling is easily managed at high power settings, it requires a little more attention than the 109 though.
