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 primarily for digital protocols like CRSF, which offer faster response times and better range than traditional PWM receivers. Most cheap PWM receivers won’t natively support ExpressLRS because it requires specific hardware and firmware. However, if your wing only has a PWM input and you want to use ExpressLRS, you can use an ExpressLRS receiver that outputs PWM signals. Many ExpressLRS receivers support multiple output modes including PWM, SBUS, or CRSF. Here’s what to do:
1. Choose an ExpressLRS receiver compatible with your wing’s PWM input.
2. Bind the receiver to your ExpressLRS transmitter module.
3. Configure the receiver to output PWM signals (using the ExpressLRS configurator or via onboard settings).
4. Connect the PWM output from the receiver to your wing’s flight controller or servo inputs.
This way, you get the benefits of ExpressLRS transmission while maintaining compatibility with PWM-only hardware. Avoid using generic cheap PWM receivers alone if you want the full ExpressLRS experience.
