So one could say that some designers sell quality receivers for long range that are single conversion, just higher quality design and filtering. I've noticed that JR for example, doesn't seem to market "park flyer" receivers. And they are single conversion RX that are perfectly dependable at out of sight ranges.
So one could say that the designations "single" and "dual" actually only mean the manufacturer who uses both is telling his buyers which are less dependable and should only be used at park flyer ranges. While manufacturers who don't use the designations at all don't need to.
The actual design of the receiver and filters is probably more important than the number of conversions,
Any help? You betcha. Thank you very much. It's actually what I remembered as an idea, just couldn't remember the words. thanks again.
