Project Notes

#662 Tachikawa KKY-1

Building the rare Tachikawa KKY1 from Ukrainian model company Amodel. No electronics in this one.



The Tachikawa KKY was designed as a light ambulance aircraft. Only 21 were produced, and it was used in the Second Sino-Japanese War between 1936 and 1940.

The initial prototype and production machines as depicted in this kit were designated KKY or KKY-1. They are distinguished by the four cylinder air-cooled, inverted inline Cirrus Hermes IV engine. The British Cirrus-Hermes Engineering Company was formed in 1931, but taken over by Blackburn Aeroplane & Motor Company in 1934.

The later KKY-2 variant switched to the 150 hp Gasuden Jimpu seven cylinder radial engine.

The Kit

According to scalemates, Amodel is the only manufacturer to have produced a model of the KKY.

Amodel is a Ukrainian model company. Their kits are distributed by IBG of Poland and available direct from IBG.

Build Log

I initially primed in black and then sprayed white. The result was coming up too “cold”, so I subsequently gave it a light undercoat of cork brown before finishing in white.


The cockpit and canopy needed a lot of fettling to get a good fit. With this kit it is well worth taking the time before paint and glue to make sure the fit is true. Luckily I was warned of this by @tochi.nocchi.


As I was going to display the model in-flight, I needed at least a pilot. there are no figures in the kit, so I grabbed one from my misc spares box - I think an Airfix pilot.


The prop was an experiment using some 1:32 plywood texture decals from proper.plane to imitate a wood finish. I like the “impression” and it was easy, but perhaps doesn’t have the detail I’ve seen some get with good old brush and paints

Whipping up a quick based with some scrap board and a rough surface sculpted from papier-mâché.


And we have take-off! The pose is inspired by the box art.

With some prop blur;-)


Found a space on the bookshelf pending a proper home..

This page is a web-friendly rendering of my project notes shared in the LEAP GitHub repository.

LEAP is just my personal collection of projects. Two main themes have emerged in recent years, sometimes combined:

  • electronics - usually involving an Arduino or other microprocessor in one way or another. Some are full-blown projects, while many are trivial breadboard experiments, intended to learn and explore something interesting
  • scale modelling - I caught the bug after deciding to build a Harrier during covid to demonstrate an electronic jet engine simulation. Let the fun begin..
To be honest, I haven't quite figured out if these two interests belong in the same GitHub repo or not. But for now - they are all here!

Projects are often inspired by things found wild on the net, or ideas from the many great electronics and scale modelling podcasts and YouTube channels. Feel free to borrow liberally, and if you spot any issues do let me know (or send a PR!). See the individual projects for credits where due.
