More IJN planes would be outstanding. I think Wotan stated in another thread about IJN torpedo planes. the following might be the reason why it's taking a while for Hitech to come up with a planeset for the PTO. if ya'll find some other IJN A/C that you think would be cool let me know, I'm still researching.
The Nakajima B5N Kate did not have armor, self-sealing tanks, forward firing MG (Only one 7.7mm in the rear) Kamikaze plane only, I reckon. Is it worth it? More is always better. Top speed 235mph
The Nakjima B6N Jill had 2 7.7mm forward and a ventral MG (7.7mm?) It replaced the Kate in 1943. reports call the Jill as not much better that Kate.
Top speed 301 mph.
These plane are the ones i have found that would be Historicaly and time accurate for planeset. We probably wont fly most of these. IJN A/C were very maneuerable, but not much else till the end of the war. thses are just some examples.
For a PTO IJN early planeset:
KI-43/ Oscar / Fighter (intro.1941)
KI-27/ Nate / Fighter (intro.1938)
KI-45/ Nick / Sort of a JAAF's version of Me-110 (intro.1942)
B5N/ Kate / Torpedo bomber (intro.1938)
D3A1, VAL / Dive bomber (intro. 1940)
D2Y2, Judy / Dive bomber (intro. 1942)
For a PTO IJN late planeset:
KI-84/ Frank / Fighter (intro . 1944)
KI-100/ Fighter (intro. 1945,Basiclly a radial version of the Ki-61)
B6N/ Jill / Torpedo Bomber (intro. 1943)
