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 for digital protocols like CRSF (Crossfire Serial) that offer low latency and telemetry. Cheap PWM receivers typically output standard PWM signals and don’t support the ExpressLRS protocol directly. However, you can use an ExpressLRS transmitter module with a flight controller or receiver that converts CRSF to PWM, but this adds complexity and latency, which may reduce performance.

For a wing, it’s best to use a dedicated ExpressLRS receiver that supports CRSF or an equivalent digital protocol. These receivers connect directly to your flight controller or servo outputs, providing better range, reliability, and telemetry. If you only have a cheap PWM receiver, you won’t get the benefits of ExpressLRS’s advanced features.

In summary, to fully utilise ExpressLRS on your wing, invest in a compatible ExpressLRS receiver rather than relying on a basic PWM one. This ensures smooth control and optimal range.
