or similar Planes, I allready asked the following question in a 109 thread, but all the people, which "knows" that the 109 had a poor handling at highspeed seem not to know what a good highspeed handling, or the result of it is...

At
http://109lair.hobbyvista.com/
is a divingtest of a 109,
the tested 109 pulled out of 70-80? dive in around 1400-1500m with only using the stick and correct trimset, or with using the trimwheel (if dive was initiated with a wrong trimset) and pushing the stick foreward to be not blacked out... both curves have the same shape so maybe it was limited by the tendency to blackout?? - I don´t know..

(it was not a test to estimate the max machnumber!!!- they tested the flightstability for the tall tail of later 109s)

Max machnumber - 0,805 at 7.0km
Max IAS - 737km/h - 4,5km
Max TAS - 906Km/h - 5,8Km

Speed when the pilots started to pull out of the dive was around 880km/h TAS (as fas as I can read it from the curves in the documents..)

Are there any values for other planes around? How many feet/meters are needed by other planes to pull out of a similar dive? Would be interesting to know..

Are there any values for Spits, P51, P47??
If a bad 109 need 1500m to level out of such a dive, how many meter of feet would a P51 need??
