I have 2 Futaba R319DPS Synthesized Rx. Just dial in the freq. you want. No more dealing with crystals or having to wait to fly. I also have a TP-FSM Synthsized Module that will fit the Futaba 9Z, 9C and the 9C Super. It will allow you to dial in any freq. in FM that you want to match any crystal Rx er you might be using or use it with the R319 DPS. My price shown is for both Rx ers and the Tx module. I will separate them out as: Rx ers....1 at $40 or both at $75 (includes free shipping and tracking #). The module is priced at $55 by itself (free shipping). Both receivers and module is priced at: $100.
