I have a Futaba 7C Radio, I currently use the New 168 RX in my models. On channel 13. I have acquired 2
older Stick planes One a .60 size and one a .25 size. I know that I have to have a low band neg. shift RX
but can I use a single conversion RX or do I have to stick with a dual? Also can you explain the Diff between
single and dual conversion.
This is the RX I use in all my current planes.

I was thinking about something like this for my sticks

I am not trying to be cheap but I don't want to spend 50+ on RX for planes
that I am not even sure how good they fly.
I've never used one but have heard that the Berg's are good full range RX's. Be sure to use their crystals.
You can use either single or dual conversion RX's interchangably but be carefuls as many single conversion units are NOT full range.
Single/dual conversion refers to the internal processing of the RF signal. Different crysatal are also used. In the dual conversion units the signal is "mixed" twice before final processing of the data stream while in the single it is only "mixed" once.
From Futaba FAQ:
Dual Conversion
A type of receiver that converts the incoming frequency through two intermediate stages. This tends to eliminate the type of interference known as "image". With high-precision components, it also allows the receiver to be much more precise in selecting the incoming channel it accepts. This is what helps the receiver to be very narrow-band.
