But, I think HTC selected most difficult version in Ki43.
because,Ki43-II have some minor version.
I showed it in forum "Ki-43 service dates?"of"Aircraft and Vehicles".
if you want know Ki43, plz check.
(notice, Version name was attached Aero detail's name"
http://www.aeroflight.co.uk/biblio/series/aero_detail/ad29.jpg"
.IJA did'nt use such name.)
and Ki43-II's Max speed is diffelent each minor versions.
I think , HTC should select Ki-43III, because Ki43-III don't have many minor versions.
(it's only Ki-43IIIotsu, having 2 Ho-5 20mm , is prototype.but Ki-43IIIkou was build over 1000.)
may be, this info is first info of many people not speak japanese, i think.
and I'm worried that many people don't believe my info, because Book in English side is not have such info.
But Japanse Book and Original IJA's resource have these info.
