Ok as promised i did a few trials with it in game (was late and i was very tired so its pretty simple), it will give you the basics.
As with all others ive done i'd be guessing the results are not 100% accurate to the exact MPH etc but VERY close.
Ok the Bf 110c4 in game
Top speed -
roughly 1000ft - 239MPH
roughly 5000ft - 245MPH
roughly 10000ft - 251MPH
roughly 20000ft - 263MPH
In a climb (between 5000-10000ft) i could manage a steady 129MPH at roughly 100ft a second. Could be just off though. This was a fairly steep climb though. In a good climb it handles its speed well (considerably better than some others).
It has a whole minutes worth of ammo (if using limited ammo!) which is good
It managed 486MPH in a vertical dive before the wings came off.
I managed to get a service ceiling of roughly 33700ft (the C4 could do 35000ft i believe?)
Maximum speed of the C4 (real life) -348MPH, at what height i dont know.
Maximum speed of the C4 (BoP) - 263MPH, at above 20000ft.
I'll do some more trials later if you need me to. Hope this helps a bit mate and puts you mind at rest or answers any questions
