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 primarily designed for digital protocols like CRSF, which offer low latency and high refresh rates. Most cheap PWM receivers output traditional servo PWM signals, which are not compatible with ExpressLRS’s native communication. However, you can use an ExpressLRS transmitter module with a flight controller that supports ExpressLRS and connect a cheap PWM receiver to the flight controller’s PWM inputs. The flight controller will then translate the receiver’s PWM signals to control your wing. For best results, use a flight controller with built-in ExpressLRS support or add an ExpressLRS receiver that outputs CRSF, which is more reliable and responsive. If you want to keep it simple, consider upgrading to an ExpressLRS receiver designed for your wing. To summarise: 1) Connect your PWM receiver to the flight controller’s PWM ports. 2) Use the flight controller with ExpressLRS transmitter. 3) Configure your flight controller to map PWM inputs to controls. This setup works but won’t leverage the full benefits of ExpressLRS. For improved performance and range, a native ExpressLRS receiver is recommended.
