• Engine protected from head-on attacks
• Most armament is nose-mounted
• Faster than most opponents, and have a great energy retention, makes it a beast using BnZ tactics.
• Can hadle multiple hits on the fuselage

Cons:

• Pusher aircraft, engine mounted facing rear, exposed to enemy aircraft which may follow
• Required to set convergence due to wing-mounted machine guns
• Poor turn rate

History

Describe the history of the creation and combat usage of the aircraft in more detail than in the introduction. If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the vehicle and adding a block "/ History" (example: https://wiki.warthunder.com/(Vehicle-name)/History) and add a link to it here using the main template. Be sure to reference text and sources by using <ref>, as well as adding them at the end of the article. This section may also include the vehicle's dev blog entry (if applicable) and the in-game encyclopedia description (under === In-game description ===, also if applicable).

Media

Excellent additions to the article would be video guides, screenshots from the game, and photos.
