The Nakajima Ki-84 Hayate (Gale) first flew in March of 1943. It was the only Japanese Army fighter with a four blade propeller.
 
The Nakajima Ki-84 became combat operational flying out of Hankow, China in 1944. Later they were based in Japan, Okinawa, the Philippines, Southeast Asia, and Taiwan.
 
At 20,000 feet the Nakajima Ki-84 was faster than a P-51 Mustang and had a better rate of climb. It could out turn a Supermarine Spitfire. A captured Nakajima Ki-84, when run on high octane gasoline, had a top speed of 428 mph.
 
Having learned their lessons from previous fighter aircraft, the Nakajima Ki-84 had armor plating for pilot protection. Pilots of the Nakajima Ki-84 enjoyed acceleration, maneuverability, and climb rates unmatched in previous Japanese aircraft models.
 
It is said that at medium altitudes, the Nakajima Ki-84 could out run and out distance any Allied fighter aircraft. However, ground handling of the aircraft was not good. The Nakajima Ki-84 had limited forward visibility when taxiing and pilots had to be ready to compensate for high engine torque when the aircraft rotated on take off.
 
As with many aircraft rushed into production, the Nakajima Ki-84 suffered from a number of quality defects. One of the most prominent was a tendency for landing gear struts to fail during hard landings. This was due to improper metal hardening during the manufacturing process.
 
In addition to being used as an interceptor and fighter aircraft, the Nakajima Ki-84 saw limited use as a fighter/bomber.
 
In April of 1945 Nakajima Ki-84 aircraft attacked Okinawa air fields occupied by the United States. A number of U.S. bomber and fighter aircraft were put out of action by the surprise attacks.
 
It is argued that if the Nakajima Ki-84 had been introduced earlier in the war and in sufficient numbers, it would have been a huge threat to Allied aircraft.
 
Nakajima Ki-84 aircraft were flown in to the 1950's by the Chinese. A total of 3,449 Nakajima Ki-84 aircraft were produced.

Radio Control Airplanes:
 
In the picture above is the RC Nakajima Ki-84 airplane from Alfa Model. The Nakajima Ki-84 radio control airplane is an ARF of foam construction. Wing span of the rc airplane is 34 3/4". Alfa Model recommends a 400 size outrunner motor to power their radio control airplane.
 
In the first picture below is the Hyperion RC Airplanes Nakajima Ki-84 ARF radio control airplane. Wing span for the RC Airplane is 45" and length is 38". Powering their radio control airplane is a HP-Z3019-10 brushless motor.
 
The second picture down is the Aerotech Models 1/5 scale Nakajima Ki-84 RC Airplane from their kit. The radio control airplane weighs about 30 lbs. with a wing span of 80" and a length of 78". Aerotech recommends a G 62 engine for their RC Airplane.
 
In the next picture is the GPI Models Nakajima Ki-84 radio control airplane. The RC Airplane has a wing span of 86.5" and a length of 78". Power for the radio control airplane can come from a G45 - 65 gas or 2.0 glow engine. All up weight for the RC Airplane is about 22 lbs.
