Was just at Toledo show and bought a Hitec 8 ch supreme rx from MPI. I told the kid when he asked what radio, Hitec but he gave me one that says JR or Airtronics TX only. I'm using hitec prisim and Futaba sue 8 radios. what is the difference? Maybe I can email MPI and see if they will switch rx's but whata pain to send it and wait for another. any suggestions? TIA
