I have a spektrum pro module for an m8. I need a receiver for it. Does anyone know if there is some kind of chart out there that will tell me what kind of receivers are compatible with my module?

The Pro module will work with all the surface Spektrum receivers (transceivers). So basically you can use all the earlier versions.. you just won't get the lower latency benefit.. won't be as fast as using the Pro Module with a Pro Receiver.
