Can I 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 for digital protocols like CRSF, which offer low latency and high reliability. Cheap PWM receivers typically output standard PWM signals and don’t natively support ExpressLRS. However, you can use an ExpressLRS receiver that outputs PWM if your flight controller only accepts PWM inputs. To do this, configure your ExpressLRS receiver to output PWM rather than a digital protocol. Keep in mind that this will increase latency compared to CRSF and reduce telemetry capabilities. If your wing has limited space or weight constraints, consider a small ExpressLRS receiver with native CRSF output and a compatible flight controller or a converter that translates CRSF to PWM. In summary, you can't run ExpressLRS directly on a cheap PWM-only receiver, but you can use an ExpressLRS receiver set to PWM output to work with PWM inputs on your wing’s flight controller. Always check compatibility and wiring carefully, and test range and response on the ground before flying.
