Using ExpressLRS with a Budget 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, which provide low latency and high reliability. While you technically can connect a cheap PWM receiver to an ExpressLRS transmitter module, it's not recommended because PWM receivers typically have higher latency and lower refresh rates compared to digital receivers. If you want to use ExpressLRS on your wing, consider using a compatible ExpressLRS receiver that supports CRSF or SBUS output. These digital receivers can often output PWM signals if needed, but it’s better to keep the signal digital for performance. To set up, first bind your ExpressLRS transmitter module with a compatible receiver. Then, connect the receiver to your flight controller using the appropriate protocol (CRSF or SBUS). If your flight controller only accepts PWM inputs, you might need a converter or use a receiver that outputs PWM natively. For a reliable, low-latency link on a wing, investing in an ExpressLRS-compatible digital receiver is the best approach.
