  • Try SeligSIM™ – free to download and run, works with any controller, does not require Steam/login.

  • SeligSIM is for anyone, whether you are a seasoned pilot, Sunday flier, or beginner.

  • SeligSIM focuses on accurate aerodynamics, ground reactions, and overall physics modeling.

  • Exceptional control feel and precise accuracy.

  • Realistic flight dynamics - aerobatics, stalls, tip stalls, spins, etc.

  • Unmatched ground reactions physics modeling, including breakable parts.

  • Continuously improved since 2003.

  • Comprehensive online User Manual, clickable from inside the simulator.

  • 50+ stock airplanes plus 90 variants. Over 140 airplanes in total.

  • Create an unlimited number of airplane variants with the Scaling Wizard™.

  • 35+ flying sites (3D and 360-deg pano).

  • 40 different photo-realistic skyscapes.

  • 24 major Feature categories.

  • 75+ specialized camera views. View your flight from practically any angle and position.

  • Many instructive on-screen messages. Over 40 categories of messages.

  • Built-in lessons cover the basics from trainers to mastering prop driven 3D aerobatics.

  • Earlier versions of SeligSIM are also marketed under the brand FS One®.

SeligSIM 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 show some of the physics effects, here are a couple of videos: take off and landings with a 60% scale J-3 Cub and an “unconventional” 110-inch span Yak 54 tail sitter, aka “RC Stunt Plane”:

Airplanes#

  • SeligSIM includes power planes and sailplanes ranging from beginner-level trainers to highly-advanced giant-sized 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 SeligSIM. In all, the stock airplanes and their variants add up to over 140 airplanes.

Scaling Wizard#

  • A unique feature is the SeligSIM 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 SeligSIM – full scale, gas powered, and electric variants. Each variant has physics that makes it feel of its true real-world counterpart.

Aerodynamics and Physics#

  • SeligSIM specializes in aerodynamics and flight physics. It accurately predicts +/-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 the simulator are based on decades of experience in RC modeling and aerospace engineering [detailed technical paper by Michael Selig, pdf].


Next Steps#

The simulator 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 SeligSIM on your PC under the included software license. While the simulator is free to install and use, it is not open sourced.

Follow the online User Manual to learn how to hook up your controller. Step-by-step instructions are in the Getting Started of the User Manual.

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