My dad is not quite the gamer that I am, but one thing we’ve always had in common is a mutual love for flight simulators. These hyper-realistic experiences are even better when you have equipment like a joystick or throttle that adds to the immersion.
Another popular role is to handle radio communications from the air traffic control tower. That’s where the Flight Simulation Radio kit comes in. This kit is compatible with X-Plane using ArdsimX, but it’s also usable with Microsoft FSX and Prepar3D (with limited support).
The kit comes complete with everything you need, but some basic soldering skills are required. You can even daisy-chain kits together to form a full radio stack. The radio is programmable for Nav, Comm, Transponder, ADF, Groundspeed, or any other output from the simulator.
