Thank you. Now the question is will any of those cause problems with fitting since they do not show up under the "complete your build" section for the tutor?
You can use any ELRS receiver that has PWM outputs.
Many or most ELRS receivers are made specifically for drones and those don’t have the PWM connections that a basic rc plane needs for servos and the ESC. Drones use flight controllers and ELRS receivers usually communicate with the flight controller with a protocol called CRSF. The flight controller then communicates with the ESCs over another protocol, but PWM is never involved.
More recently, ELRS receivers with PWM connections have become more common, such as the ones that Litterbug listed. You should be able to use any brand of ELRS receiver, as long as it has those PWM connections. They will work just fine with your Tutor build, but the binding instructions will be different. It’s a little more complex, but ELRS is the “latest and greatest”, so you may as well learn it straight away.
Good luck!
