Ki-100 is a decent ride, good firepower and overall stats - however it still suffers from one major flaw in which its top speed is only 360mph, granted its still one of the finest aircrafts the Japanese produced during the war.
Contrary to the myths - the Ki-100 did not fair to well during the war, with a lack of skilled pilots - it didn't perform to well in combat - however in a few engagements flown by veteran pilots - it was well liked for its ability to combat the best the US had to offer.
