Using 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 communication and works best with receivers that support CRSF (Crossfire) or ELRS protocols. Cheap PWM receivers typically output a simple pulse-width modulated signal for each channel and do not support the bidirectional digital link ExpressLRS requires. However, you can still use an ExpressLRS transmitter module to bind and fly with a PWM receiver, but you will lose the advanced telemetry and low latency benefits of ExpressLRS.

For a wing, if you want reliable control and telemetry, it’s better to invest in a dedicated ExpressLRS receiver that matches your transmitter module. These receivers are lightweight, affordable, and provide better range and response. If you must use a PWM receiver, connect it directly to your flight controller or mixer board and configure your transmitter to output PWM signals. But this setup won’t leverage ExpressLRS’s full potential.

In summary, while possible to use ExpressLRS with a cheap PWM receiver, it’s not recommended. For best performance and features, use a native ExpressLRS receiver on your wing.
