There are lots of myths out there about the FW-190A.
If you do a search for the FW-190 you will see some of these myths explained.
Kweassa is correct. The FW-190A8 should be the more nimble version of jagd-einsatz's when comparing the FW-190A5.
The full combat weight differences between the FW-190A5 jagd-einsatz's and the FW-190A8 jagd-einsatz's are:
FW-190A5 - 4106kg's
FW-190A8 - 4272kg's
This assumes full fuel, full ammo, a 100kg pilot (w/o equipment) and adds in the winterization kit with full oil load for the kit.
The armour was exactly the same for the two planes.
The FW-190A8 BMW-801D2 motor develops 1900PS at FTH in a derated motor and 2100PS in a rated motor. Only jagd-einsatz's used rated motors.
The FW-190A5 BMW-801D2 develops 1700PS in a derated motor and 1800PS in a rated motor at FTH.
Shouldn't the A series have a slightly better roll rate than D series?
Yes it should. The Dora rolls very well but not quite as fast as the FW-190A series. The Dora turns better than the FW-190A series. It was lighter than the FW-190A8 and developed 2250PS at FTH with MW-50. The majority of Dora's were equipped with MW-50 by the end of the war. The Dora also had even less drag than the A series.
I will be gone for the next few weeks. Doing some traveling in order to further research my book.
