I used a Pébéo Drawing Gum Marker 0.7mm for the masking. It is an experiment - seems to work well as long as one does this over a very hardy paint. Here it is fine with Mr Hobby Aqueous .. over Vallejo MC, the gum marker just scratches off the paint!

キ84 疾風! Arma Hobby provide 6 schemes in their Ki84 Hayate boxing. I finally broke my #buildersblock choosing the “green camel” factory ferry scheme sighted in Saigon, 1944. It was the most attractive, but also the most challenging - I decided “just go for it!”

As I work through my stash of @armahobby kits, I continue to be amazed by their quality. I have fond memories of their earlier PZL P7.a and TS-11 Iskra kits. Maybe next I’ll start on their Hurricane series.

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.
