Technische Anweisungen des General der Truppentechnik

The handbook confirms it. In fact, according to TAGTT 151/152, any Bf 109 G could increase VNE to 850 km/h at 1km and 800 km/h at 3 km if it had the following requisites: 1) Enlarged tail fin & rudder 2) Horizontal stabilizer trim range reduced from +2º to +1º 10' 3) Elevator fitted with...

Copies of this report are available in several public archives in USA (NASM ) and Europe (IWM, EADS), in microfilm and paper form. Tell those "professional fake-report detectors" to look for microfilm reel 2617, and maybe they will stop spreading nonsense... And FWIIW, Mtt project office...

Yes, they are calculations, but without details on exact configuration. It's also unclear the source for the G-10 curve in Samoletostroenie v SSSR. 1917–1945 book.

Both come from Mtt AG Projekbüro: - the one for DB 605 DM was in one of GL/C-E2 performance summary sheets - the other for DB 605 DC came from sheets A/IV/39/45 "Steiggeschwindigkeiten für 8-109 G10 mit DB 605 DCM" (20.1.45) and A/IV/40/45 "Höchstgeschwindigkeiten für 8-109 G10 mit DB 605 DCM"...

Propeller looks like VDM 12087A, so it might mean DB 605A or 601E experimental installation.

Mtt AG also tried to do a fighter from the racer a fighter, unsucesfully ;) The problem with the second incarnation (Me 209 "II") is that there isn't many primary sources neither for its flying qualities nor its performance, so anything written about it (V5, V6 or V7) must be taken with a grain...
