The SP series of Sangonomiya Aerospace Manufacturing Corp. (Sangonomiya aircraft for short) consists of 3 variants. The SP-21 for the Utility variant, able to seat 2, with twin 1000 hp tuboprop engines, the SP-24 with twin 3000 hp turboprop engines, which can seat 4, and the SP-31, a leisure variant with twin 2000 hp turboprops and can seat only one.

The aircraft is a low swept wing seaplane with V tails, and has a range that can take it all the way from Sangonomiya Island to Liyue Harbor.

The SP series gained popularity in the General Aviation industries that Sangonomiya Aircraft even decided to export the SP-31 to Fontaine to compete with other Fontaine-built seaplanes.


It was at the beginning of the Vision Hunt decree when the SP-31 would prove as a useful asset as a scout/reconnisance aircraft before the full blown war. The Watatsumi Resistance under the Divine Priestess Sangonomiya Kokomi ordered a fleet of SP-31s to be used as trainer and recon aircraft for the upcoming battles against the Shogunate.

    @WinsWings that would work, I just need to find a way to get the center of mass to align with the center of thrust

    @WinsWings I'll try doing that, Maybe a higher-wing version, then the holders for the wing floats are a little extended
