Using 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 for high performance and low latency, typically using serial protocols like CRSF rather than PWM. While you can technically connect a cheap PWM receiver to your ExpressLRS transmitter, it won't provide the benefits ExpressLRS offers, like improved range and faster response. For a wing setup, it’s best to use an ExpressLRS-native receiver that supports CRSF or SPI. These receivers are small, lightweight, and easily integrated into wings.

If you already have a PWM receiver, you can use it with your transmitter, but you won’t get ExpressLRS’s advanced features. To upgrade, follow these steps: 1) Buy an ExpressLRS-compatible receiver (e.g., ELRS 2.4GHz 4/8CH). 2) Bind it to your ExpressLRS transmitter module. 3) Connect the receiver to your flight controller using UART (CRSF) or SPI ports. 4) Configure your flight controller to recognise the receiver protocol. This setup ensures reliable control and maximises your wing’s performance.
