Software emulators designed for RealFlight 7 were built during the Windows 7 and Windows 8 eras. Modern operating systems like Windows 10 and Windows 11 feature strict driver signing enforcement, which often blocks these unsigned emulators from running or causes system-wide Blue Screen of Death (BSOD) crashes.
When Knife Edge Software and Great Planes offered RealFlight 7 (and its subsequent 7.5 update), the simulator was packaged explicitly with physical hardware. The software was rarely sold as a standalone digital download during its initial life cycle.
Many pilots preferred to practice using their actual field radios (like a Spektrum DX8 or Taranis) rather than the plastic InterLink controller. Since the software locked out non-InterLink devices, emulators were used to "trick" the software into thinking a standard USB adapter was an InterLink unit.
RealFlight 7 and its update, 7.5, marked the tail end of an era where Horizon Hobby and Great Planes relied heavily on this hardware-level protection. The InterLink Elite controller was the standard for this version, acting as both the software's copy-protection dongle and the user's radio transmitter. The "emulator" was created specifically to decouple the software from this requirement. realflight 7 dongle emulator 19
: RealFlight 7 is a legacy product. Most modern RC pilots have moved to the RealFlight Evolution platform, which removes the need for legacy dongle emulators by supporting direct USB input for most standard radios.
(often referred to as version 19 or similar) is a software workaround designed for the RealFlight 7.5 RC Flight Simulator
The landscape of RC flight simulation has drastically shifted since the days of RealFlight 7. The necessity for complex hardware emulators has largely been rendered obsolete by changes in how the software is distributed and licensed today. Software emulators designed for RealFlight 7 were built

This dongle acts as a physical key. When you purchase a legitimate copy of RealFlight, it comes with either a dedicated transmitter controller (like the InterLink Elite) or a small USB interface dongle to which you can connect your own radio. This dongle must be plugged into your computer's USB port for the software to launch. Without it, the software remains locked. The RealFlight software can even be downloaded for free, but it won't function without this hardware key. The software was rarely sold as a standalone
Is RealFlight Evolution as bad as everyone says? : r/RCPlanes
It gave pilots a realistic, physical transmitter layout with authentic gimbals and switches.
If you own a valid copy of RealFlight 7 but have lost or cannot use the InterLink controller, or if you simply want to avoid the risks of shady software, there are legitimate ways to get it working.
