The Ki-84 is one of the best planes in Aces High....it turns tight and can be pushed to 453mph (fastest I've gotten it in a dive),has one of the best climb rates...better than any Me-109 or P-51, from 100 mph at sea level it only takes about 42-43 seconds to reach 300 mph, and with little more than cutting off your engine and a few quick rudder kicks, can slow down from 425mph to little over 200mph in under 3-4 seconds, allowing to to go from a flat out dive about to over shoot to 400 or less off your 6:00 and ripping you to pieces with its wing mounted 20mm auto-cannons... truly an amazing fighter when in good hands..
