The Grumman G-21 “Goose” is a classic from the early days of aviation. Designed in the 1930’s to ferry New York businessmen up the coast to their weekend retreats, it was also designed to take off and land on the water.
In FSEconomy
In FSE, the plane carries 9 passengers and can be had for v$450,000. The monthly cost is ~v$3,000.
With a capacity of 9 passenger, it sits in a sweet spot for FSE in that it’s not too hard to fill and you don’t get totally eaten by booking fees (which kick in once you put more tha 5 assignments in the same plane).
In FSE, there are currently (at the end of December 2025) only 8 planes listed for sale.
Turbo Goose
In FSE, there is an additional plane model called the “Grumman Turbo Goose”. This seems to be based on a modern effort to upgrade the engines, etc of the “classic” Goose.
In FSE, the Turbo Goose is much less common, with only a single, bank-owned plane currently (late December 2025) for sale (at ~$600k). Monthly costs appear to be ~$3,300.
The FSE model sticks with a 9 passenger capacity, but increases the cargo capacity from 1,343 kg to 2,418 kg and increases the (nominal) cruise speed from 155 knts to 200 knts.
In Microsoft Flight Simulator
Retractable landing gear; can also land on water. No autopilot.
The inclusion of the G-21 in MSFS 2024 is a delightful inclusion. It’s flying from a previous era, and without modern conveniences like autopilot or even a wing leveller!
Overall, the plane seems to fly well, if requiring full manual control.
The included model has quite a bit smaller tanks than the FSE configuration (110 gal vs 170 gal per side), and so I created a variant to match FSE. The Turbo Goose FSE model has even bigger fuel tanks (211 gal per side), and so while the variant includes big enough tanks to technically accept a full fuel load, it puts the plane over the Maximum Takeoff Weight.

My FSE Tanks variant is available to downloadable from GitHub or discuss it on the FSEconomy Forums. Also included is a second variant that FSEconomy maps to the Turbo Goose.
One of the nice changes in MSFS 2024 is that variants and liveries are now separated, so liveries should work with my variant above without other changes.
