The Spektrum GPS Module: Sportsman + is a GPS add-on for compatible aircraft setups that unlocks GPS-related features such as Virtual Fence and Autoland. Buyers generally like its solid build and Spektrum-style integration, but installation and first-time calibration can be setup-heavy, and the price is a common sticking point.
The FAS Receiver, 315Mhz is a compact, 315 MHz remote receiver intended for specific LiftMaster models. Buyers report easy pairing and solid real-world range for gate and garage-door style setups, with the main caveat being that range expectations vary by install and a small number of users report shorter coverage.
