From a discussion on the "beginners guide to planes" i took these two bird up in training mode to see how they compared (curiosity really) and ehres what i came up with, bear in mind these probably wont be accurate to the exact MPH but its going to be very close -
TOP SPEED
P51D -
Below 1000ft - 298MPH
roughly 5000ft - 315MPH
roughly 10000ft - 331MPH
roughly 20000ft - 304MPH
109K -
Below 1000ft - 331MPH
roughly 5000ft - 339MPH
roughly 10000ft - 356MPH
roughly 20000ft - 392MPH
Rate of roll P51 is superior
Ammo cap P51 -29-30 sec
109k - 9-15 sec worth
Rate of climb 109 is superior
Cockpit vis 109 is better (prior to patch release, then P51 will be)
Weapons 6 MG's 2 MG's 3 Cannons
Please note this isnt 100% accurate but roughly what i came up with from trials i did on training. I maxed out the throttle with both and left it for a good 30 seconds to see if speed would increase. So speed could be/prob will be slightly different than stated (but marginally).
Ammo cap is the amount of time you'll get if limited ammo is enabled, so keep note of it
for the 109 you get 9-10 seconds worth of cannon fire and 15 seconds worth of MG fire. (roughly)
Remember this is also prior to the patch. Its highly likely that the 109 will stay as it is? but we all know the P51 will be "fixed". I look forward to "trials" once its sorted.
Im not a huge fan of the 51 or the 109 so im not sure if the above speeds are correct (roughly) for the models. Can anyone help?
I would imagine the P51 would be faster but from the test can see it has more speed at a higher altitude which i assumed it would as it was a high altitude escort
Overall it would appear the 109K is far superior. A few (not in depth) would also suggest its better than the spitfire XVI, though im yet to do a "proper in depth" test yet.
