The Feiying launcher is particularly popular because it supports a wide array of transmitters, ranging from entry-level brands like to advanced Futaba or JR units.

The headline feature of version 14 is the Dynamic Memory Paging System . FS2020 and X-Plane 12 are notorious for "memory creep" during long-haul flights. FSL14 runs as a low-level monitor, automatically purging standby memory and optimizing page file usage without requiring a simulator restart.

This is the most critical section. Because FeiYing Simulator Launcher 14 is closed-source and originates from an unknown developer team, you must assess the risks.
