Flight Simulators At Their Finest

Knife Edge Software creates world-class flight simulation software. For nearly three decades, our most famous product has been a hyper-realistic RC (radio-controlled) aircraft simulator known as RealFlight. RC pilots have depended on RealFlight to practice everything from basic flying fundamentals to advanced aerobatics. In our hands, RealFlight evolved into an indispensable tool allowing countless RC pilots to safely and affordably refine their skills.
In November of 2021, we made the difficult decision to close our final chapter with RealFlight. Its legacy will continue under the capable direction of Horizon Hobby. We sincerely thank everyone who has supported and contributed to RealFlight over the many years. Moving forward, we are thrilled to begin producing powerful new flight simulators and other high-caliber products. Please stay tuned for future updates!
