If you were trying to use wireless around a number of large motors and lots of noise is there is a "best" method to look at? I have used the Nordic nRF24L01+ where you can send some limited data control signals Prop to Prop. 1 Master module talking to multiple slaves. Even if there was a packet failure there is time to make multiple attempts to get a chksum to pass. 50' max. 25' minimum.
