Ron your Tx certainly can operate a single conversion Rx. The filtering senario used by the Rx has nothing to do with the Tx. Also you do not have to stick with Futaba Rx's, in some cases the cheaper after market Rx's are superior performers as a matter of fact.

Don,t confuse the Rx conversion methods with modulation shift. This is an entirely differant matter and not being an electronic egg head I am not going to try and explain. What is important for you to understand is that the Rx and Tx must be of the same shift, either positive or negative. Most aftermarket Rx's can be ordered in the shift required and some are switchable. Also sonme Tx's are selectable for either shift but this is a valuble function that you will never see on any Futaba Tx, All Futaba Tx sold in north america are Negative shift.
