What is the difference between R309-DPS and R319-DPS? Is it better in any way? newer design? I have two R309 and have ordered a R319.
Thanks

The R319DPS is a newer version of the synthesized receiver. As technology changes, Futaba will redesign their equipment to take advantage of it.

Hi,

The R319 is my first 9-channel receiver. I assume I should plug my 6 volt power into the channel marked "9/B", but could not find this documented anywhere in instructions or on Futaba website. Thank you.

Use a Y-harness to plug the battery power lead and any servo lead into the receiver in any servo channel. Power can be applied in any of the slots in the receiver.

I hope you find this information helpful. You can also reach our Futaba support technical team at 217-398-8970, or via fax at 217-398-7721.

Could we get a little more technical detail on the difference?

Over time, certain components go out of production. The receiver then needs to be redesigned with newer components that are available. There are no performance differences between the R309DPS and R319DPS receivers. They are slightly different in design because of the differences in components.
