Can You Use ExpressLRS with a Basic PWM Receiver on a Wing?

Question: Can I run ExpressLRS with a cheap PWM receiver on a wing?

Answer: ExpressLRS is designed primarily to work with digital protocols like CRSF rather than traditional PWM receivers. Most cheap PWM receivers won’t natively support ExpressLRS because it requires a compatible receiver that can handle its high-speed digital signalling. However, if your wing has a flight controller that supports ExpressLRS and has PWM inputs, you could technically connect a cheap PWM receiver, but you won’t get the benefits of ExpressLRS’s low latency and long range. For best results, use an ExpressLRS-compatible receiver, usually with a dedicated CRSF or SPI interface. These receivers are widely available and affordable, often around £10-£20. To upgrade, bind your ExpressLRS transmitter module to one of these receivers, connect it to your flight controller, and configure your firmware accordingly. This setup ensures optimal performance, range, and reliability on your wing.
