OK, in that case the only thing we can do until the module becomes available is to look at other games - which of course will be highly dependent on the specific implementations and quirks of each game’s flight models.
In Aces High Mosquito FB.VI get to fight 109K and 190D and I have a bit of experience with that. Both the 109 and 190 have a significant speed advantage at all altitudes, and increase with altitude. There is no escaping from these planes.
The 190D can BnZ the mossie from dusk till the cows come home - if it plays it timidly. In a knife fight the mossie EAT the dora, with a better circle and slow speed handling, specially if flaps are used. This assumes that the mossie can engage its WEP which makes a huge difference.
The 109K is much closer to the mossie in a knife fight. Its major advantage is that it build energy incredibly fast, so if the mossie can’t win the fight quickly, it is very likely to lose. The 109k can also BnZ the mossie as much as it wants if it plays it safe and doesn’t push too hard.
Should the fight start with E advantage to the mossie, both of these planes are in big trouble. The only escape for the Dora is to dive to very high speeds, and the 109 must try to evade long enough for it to equalize the energy states. One mistake from them all it takes for the quad hispanos to evaporate them.
This is how it plays in Aces High.
