FS One is also marketed as the new SeligSIM 2024.5

If you want to download the latest version of the InertiaSoft RC Flight Simulator, it is SeligSIM 2024.5. You can download this version from the new site and user manual below:

FS One can work with practically any USB simulator controller. After your download, follow the setup instructions in the online User Manual, to get going. The Getting Started section (Parts I and II) is the only essential reading.

To showcase some of the physics in FS One, here is a video of an “unconventional” RC model in FS One – testing out a 110-inch span Yak 54 tail sitter, aka “Stunt Plane”:

Features

  • FS One has a rich set of features, including many on-screen navigation aids. See the Features grouped into 24 major categories.

Airplanes

  • FS One includes power planes and sailplanes ranging from beginner-level trainers to highly advanced model aircraft.

  • Airplane features include:

    • Jet propulsion, prop driven, gas/glow/electrics.

    • Movable control surfaces: ailerons, flaps, rudder, elevator, spoilers, and more.

    • Physics: P-factor effects, landing gear and wings that flex under loads, wheels that turn, breakable parts, crash sounds, real engine sounds, smoke and exhaust effects, air-swoosh sounds.

    • Graphics: photo-realistic textures/skins, accurate models.

    • Types: traditional model airplanes, 3D airplanes, scale models, warbirds, foamies, trainers, and more.

  • The snapshot below shows some of the airplanes in FS One. In all, there are over 140 stock airplanes and their variants.

Scaling Wizard

  • A unique feature is the FS One Scaling Wizard™. It is a physics-based airplane re-sizing method. It integrates into the flight simulator as an extension to the traditional airplane editor.

  • The Scaling Wizard can be used to resize an airplane along with its physics - going down to tiny micro UAV sizes up to full scale and even larger.

  • Creating new variants with the Scaling Wizard is easy and can take less than a minute (see the YouTube video below).

  • Below are three variants of the Pawnee in FS One – full scale, gas powered, and electric variants. Each variant has physics that makes it feel like its true real-world counterpart.

Aerodynamics and Physics

  • FS One specializes in aerodynamics and flight physics. It simulates +/-180 deg high angle of attack and high sideslip flight, including stalls and aerobatics such as spins, knife edge flight, inverted “harriers”, etc.

  • The data and calculations are all “under the hood”, but you feel it “pushing air” when you fly.

  • The methods coded into FS One are based on decades of experience in RC modeling and aerospace engineering [detailed technical paper pdf].


Next Steps

FS One requires a USB simulator controller and modest graphics support. Using an RC transmitter or RC simulator controller is highly recommended.

You can Download and install FS One on your PC under the FS One software license. While FS One is free to install and use, the simulator is not open source.

Follow the online User Manual to learn how to hook up your controller. Step-by-step instructions are provided to make the process go as smoothly as possible.

When you download FS One, we hope you support it with a donation in the amount of your choosing. FS One will continue to improve with your support.
