Open for discussion.

Yes please!  More low-tier aircraft would be wonderful.  +1.

Is the 250 kg load kamikaze or standard attack?

250 kg is not standard load but used for standard attack (maybe frontline modifications). When Kamikaze attack they load 500 kg.

After the WW2 this plane has captured by french " armée de l'air "

But he was only used for a transport mission

+1 Would make for a nice 1.0 dive bomber

[Z3r0_ 4,128]

250 kg is an adequate payload for a BR 1.0 dive bomber.

[Hronomant 182]

In a number of Japanese sources there is information about the use of 500 kg of bombs on this aircraft during "special attacks", which is sufficient to ensure the combat effectiveness of the aircraft
