The Ki-102 otsu has a decent speed advantage over most enemy planes in a straight line or dive and very good climb rate. The climb rate is typically better than almost every aircraft it will come up to combat against. As with most Japanese heavy fighters, it is a very fast aircraft. The aircraft is as manoeuvrable as you would expect from a heavy fighter, though quite sluggish in a turn compared to a single engine aircraft. The Ki-102 otsu has good acceleration in a dive due to its two powerful engines and increased weight and decent acceleration when travelling in a straight line.

Usage in battles

Describe the tactics of playing in an aircraft, the features of using vehicles in a team and advice on tactics. Refrain from creating a "guide" - do not impose a single point of view, but instead, give the reader food for thought. Examine the most dangerous enemies and give recommendations on fighting them. If necessary, note the specifics of the game in different modes (AB, RB, SB).

Pros and cons

Pros:

• Powerful 57 mm cannon
• Self-sealing fuel tanks and decent survivability, unlike many Japanese aircraft

Cons:

• Weak defensive armament
• Rather slow for its BR

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 If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the vehicle and adding a block "/ History" (example: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></ref>, as well as adding them at the end of the article with <references />. 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.
