Can I use ExpressLRS with a cheap PWM receiver on a wing?

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

Answer: ExpressLRS is designed to work primarily with digital protocols like CRSF, which offer low latency and high reliability. Using a cheap PWM receiver with ExpressLRS isn't straightforward because PWM is an analogue signal type and ExpressLRS transmitters usually output digital signals. However, if your receiver supports PWM output, you can connect it to your flight controller’s PWM inputs, but you won't benefit from ExpressLRS's full capabilities like telemetry and low latency. For a wing setup, it’s better to use a dedicated ExpressLRS receiver that supports CRSF or SBUS output. These receivers are affordable, reliable, and easy to bind with your ExpressLRS transmitter. To upgrade, buy a small ExpressLRS receiver compatible with your wing’s space constraints. Connect it to your flight controller via SBUS or CRSF, and configure your flight controller to use that input. This setup ensures you get the best range, response time, and telemetry features ExpressLRS offers, which is particularly useful for fixed-wing aircraft flying longer distances.
