I'm buying the JR7202. If I were just using it for park flyers I would get the Spektrum. I have the Spektrum DX3 for my Losi and love it. My LHS is a JR dealer so that leans me towards JR for service and help with the radio if needed. To answer your question, yes you can use your Tx with other Parkzone planes just put in your receiver, set it up and go.
