ok BOB,heres the skinny on radios and recievers.You still cant mix match Futaba,Jr, Airtronics or Hitech radios and recievers. What u can do is get hitech recievers for any of these radios tuned to that radio freq. Now heres the tricky part, the Prism radio with the synthasize modual will operate any FM futaba reciever accept the PCM models. No futaba radio will operate any Airtronics or JR recievers and vice versa. As for the servos,u can use ANY make of servo for and brand of radio! All you need to know is that on both Jr and Airtronics servoes you'll need to swap the possitive and negative wires in the plug to use them with a Hitech or futaba.

Hope this helps you out, Art
