This is one of the Hitec receivers previously mentioned. It will work with JR/Airtronics (positive shift) radios as well as Hitec/Futaba/Tower transmitters (negative shift). The Hitec Supreme IIs is also one of the finest 72Mhz FM receivers ever made.
I've also flown the GWS RD8SL for a number of years:
The GWS RD8SL is also an 8-channel dual conversion full range FM receiver. It is shift selectable to work with JR/Air radios or Futaba/Tower/Hitec transmitters, also.
Hobby King stocks the RD8SL 72Mhz FM receiver and sells them for $24.95. The last time I bought GWS dual conversion crystals, I ordered them from
www.allerc.com at a very reasonable price.
Good luck and good shopping!
