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 to work primarily with digital protocols like CRSF (Crossfire) or ELRS native UART communication, not standard PWM receivers. A cheap PWM receiver simply outputs servo pulse signals, which ExpressLRS transmitters and modules don’t natively decode. To use ExpressLRS on your wing, you’ll need an ExpressLRS-compatible receiver, which communicates via a serial protocol (usually UART). Here’s what to do: 1. Purchase an ExpressLRS receiver compatible with your transmitter module. 2. Connect the receiver to your flight controller via UART, ensuring it supports the protocol. 3. Configure your flight controller to accept ExpressLRS input. 4. Bind your transmitter module to the ExpressLRS receiver. Using a cheap PWM receiver will limit your control options and won’t provide the low latency and range benefits of ExpressLRS. For best performance and reliability, invest in a suitable ExpressLRS receiver rather than trying to adapt PWM receivers.
