The FrSky module and receiver work together as a transmitter and receiver pair for controlling radio-controlled models. The module acts as a transmitter that connects to a remote control (radio) to send signals, while the receiver is a compact device on the model that picks up these signals to manage its movements. FrSky systems are available in various versions, including long-range (900MHz) and dual-band options, catering to a range of budgets from affordable to high-performance. You can find a variety of high-quality options exclusively at RCProduct.in.
