This is an USB interface cable for R/C simulator. The device looks like a standard HID joystick for operating system and converts up to 8 PPM channels from transmitter into joystick axes and optionally – buttons. If you know about radio controlled models and their PC simulators like FMS, Aerofly Pro Deluxe, RealFlight G2/G3 and Reflex XTR, and if you are an owner of PPM transmitter box then you definitely know how to use this device.
Basically this is a project for R/C models enthusiasts and it’s helping them simulating the control of their device.
