Ki-43-II Hayabusa/Oscar WWII fighter 1100mm (L3D)

The Nakajima Ki-43 Hayabusa was better known under the US code name Oscar. Based on the Japanese experience in Manchuria, the army and its pilots wanted a super agile killer as a replacement for the Ki-27 Nate that had a fixed landing gear and open cockpit. The result was this airplane that became the Imperial Japanese Army main fighter during the first half of the WWII in the Pacific theatre.

The Hayabusa was often mistaken for an Mitsubishi A6M Zeke/Zero. Very light airframe, light armament, not much armor, nor self-sealing fuel tanks, but very agile and excellent turning rate due to its automatic flaps system. The 2nd generation, as the Ki-43 II, was much improved and was built in large numbers.

This 1100mm wingspan rendition of the Ki-43 II is powered by a 4108 with 600Kv or a 3536 outrunner for optimum performance and is designed to be printed with parts in LW-PLA, and several key parts in PLA+, like the forward fuselages sections, inboard wings sections, motor mount, spinner, servo and battery tray. The design has carefully planned internal structures for LW-PLA slicing resulting in clean parts with minimal oozing. Major slicer support is provided to quickly print clean parts.

Included with this file:
• Factory files for Simplify3D v4
• Cura 4.13.1 3MF files
• Valid STL files for all components

UPDATES:
2024-02-17: Added servo covers for the wings. Updated instructions.
2024-03-05: Updated servo tray and added missing GCode files. Use BatteryClips instead of BatteryTray. Updated instructions for the list of parts to be scaled at 100%.
