Can I use ExpressLRS with a basic PWM receiver on a fixed-wing plane?

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

Answer: ExpressLRS is designed primarily for digital serial protocols like CRSF, not standard PWM receivers. While you might find cheap PWM receivers compatible with your transmitter, using ExpressLRS with a basic PWM receiver isn’t straightforward or recommended. ExpressLRS transmitters output a digital protocol that PWM receivers don’t understand directly. For a wing, it’s best to use an ExpressLRS-compatible receiver that supports CRSF or similar digital protocols. These receivers offer lower latency, better range, and more reliable control compared to PWM. If you have a wing with a PWM-only receiver, you’d need a converter or a flight controller that can interpret ExpressLRS signals and output PWM, which adds complexity and potential points of failure. To get started, buy an ExpressLRS receiver designed for your setup, bind it to your ExpressLRS transmitter, and connect it directly to your flight controller or servos. This ensures full compatibility, simpler wiring, and optimal performance for your wing.
