Key Takeaways:

The North American P-51 Mustang is widely acclaimed as the world's finest fighter in its class, continuing to be a staple in air races and seeing limited service despite production ending in 1946.
It is considered a challenging aircraft to fly, especially during takeoffs, with its performance significantly improving after adopting the Packard Merlin engine instead of the original Allison.
Key developments include the P-51D model's iconic bubble canopy, and post-production, many Mustangs have been modified with engines over 2,000 hp, with a notable variant being the F-82 "Twin Mustang."

Many experts agree that the North American P-51 Mustang is the world’s finest fighter plane in its class. Most air races around closed circuits include a large percentage of Mustangs. Quite a few P-51s have been converted to seat two persons. Although the Mustang went out of production in 1946, it is still in service in some places in the world. By civilian aircraft standards, the Mustang is a difficult plane to fly; it is considered especially tricky on takeoffs when the engine torque requires expert pilot handling. Designed originally for the V-12 Allison engine, the P-51’s high-altitude and power performance did not live up to expectations. So, the 1,450-hp Packard Merlin became the standard powerplant.

There are several models of the Mustang, but the F-51 D was the first version to feature the trimmed-down rear fuselage and bubble canopy. Earlier Mustangs looked similar to the Spitfire. Today many Mustangs have been modified to handle engines with an output of over 2,000 hp. An interesting mutation of the P-51 was the F-82 “Twin Mustang.” Essentially, it was two Mustang fuselages joined by a constant-chord center section and a rectangular tailplane. It was used as a two-seat long-range escort fighter and had a maximum speed of over 475 mph.
