I meant flight test performance data, nrshida, for particular airframe-engine combinations.
I know the engine / airframe combinations to a point but it's not an exact science. Some of the types were produced contiguously and some of the serial numbers incremented by an amount to make room for the parallel production. No one is sure how many Otsu were made as they were essentially filtered in on the production lines and they are almost indistinguishable externally so photographs don't help. Many records were destroyed by the Japanese. The Early / Late Production Ko business took an age to work out as Westerners use the Ia, Ib, Ic designation a lot and this contributes to the confusion.
I am very wary of information on websites, but I read a few days ago the Homare was designed around 94 octane fuel, but the fuel most squadrons got was worse than that. This situation was exasperated towards the end of the war although I know they were stocking up on fuel, aircraft and pilots for the planned mainland defence. It must have been bedlam, many of the instructors took it upon themselves to ram the U.S. bombers.
I'm sorry Bighorn, I do not have the complete ATAIU-SWPA flight test myself. If I had it I would share it with you.
FTJR, Yipee! PM sent, 1000 thanks
Butcher the twin 30-mm is erroneous, they were so short of the 30-mm which were still developmental that as few as three models flew in anger with this type (plus 2 x Ho-5 in the cowl). I know some of the books show twin 30-mm but this is believed now to be untrue. Even the developmental aircraft sometimes flew with the 30-mm removed they say.
