I fly Hitec Supreme receivers with my Futaba 7C. I also fly the GWS RD8SL receiver available from Hobby City for $24.99 plus $3.99 for the crystal. This receiver (I own three) works wonderfully with my Futaba radio but is also shift selectable and will work equally well with JR or Airtronics transmitters.
The RD8SL is a full range, dual conversion receiver just like the Hitec Supreme IIS or Futaba R168DF. Two receivers and two crystals are just under the maximum weight for $5 shipping. Because of this outstanding value, Hobby City is frequently backordered, but they get them in all the time.
If you want a great receiver value for your 72Mhz FM radio, this is it. I'm flying my King Kobra with this receiver.
