The Tachikawa R-HM is a refined two-seat cabin version of the Mignet pre-war Flying Flea, powered by a 90 hp Continental C90-12F engine. It is generally similar to the H.M.310 Estafette produced by Avioes Mignet do Brasil.
The R-HM is a tandem monoplane or heavily-staggered biplane, lift being divided between the two surfaces which give a slot effect.
The registration was JA3094.
