About this Plan

Nakajima Ki-43 Hayabusa (Oscar). Pseudo dime-scale rubber model. Japanese WWII fighter.

Direct submission to Outerzone.

Quote: "This is a personal favorite model of mine, another great design by friend Tom Akery, pseudo-dimer (16 inch wingspan) and a real eye-catcher. There’s just something about that color-scheme, HQ chutai 20th sentai, IJAAF that jumps out at me…Nakajima Ki-43 I Hayabusa (OSCAR). A word of note: In his rush to get the plan to me, Tom positioned the wing a bit higher than on the actual aircraft. No matter…easily lowered during construction. Tom has since redrawn this plan (a number of years later) but since this was the original that I worked from…here it is. I love this model…and Tom’s design work.

Researching a model during construction is a point of enjoyment for me and generally, I like to build with a theme in mind. As I recall, for me, the Hayabusa was “The Zero that wasn’t.” While the Mitsubishi Zero was heavily armed, the Hayabusa was anything but. On the other hand, it was far more maneuverable than any contemporary aircraft in the air…and remained so to the very end of the war. Major Thomas McGuire, one of America’s highest scoring aces in the Pacific Theater lost his life while attempting to turn inside OSCAR at low altitude. How many Allied aviators, at first glance, thought they were dealing with a Zero…only to discover belatedly they were attempting to dogfight with OSCAR? In spite of its ever-increasing design shortcomings, the little Nakajima fighter was the ultimate dog-fighter…from beginning to end. If ever there was an enemy aircraft that called for use of a hit n’ run tactic, it was the Nakajima Ki-43 Hayabusa. Watch your “six” and don’t mess with OSCAR!

My model utilizes a two-bladed propeller, standard for an OSCAR. Prop design is as per vintage Comet Models, i.e., balsa blades, cardstock hub, and shaped balsa spinner.

Thanks Steve and Mary for your work and dedication!"

Update 22/4/2022: Replaced this plan with a revised version, thanks to Tom Akery.

Quote: "Neal mentioned the main wing being located too high on the original plan. This has been corrected and I wanted to send the amended plan. Better late than never, I hope! Thanks for your great site and the modelers on our site use your plans frequently. Thanks again, Tom Akery - Sky9pilot/Administrator"

Another Akery plan, simple but very effective and accurate in outline. I know the Japanese Air Self-Defence Force (JASDF) aerobatic team is named the Blue Impulse* (Buru Inparusu, God bless the Japanese language!), might this flamboyant Ki.43 be a forebear?

* Credit field

The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.


This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
