FMA suggests that the Co-Pilot doesn't work properly with "certain" Futaba receivers. The problem is a result of "certain" receivers sending data out channels 1 and 2 simultaneously, rather than one after the other. They don't offer any more than that - like which receivers work or don't work. So, my question is: does the R138DP output data on 2 or more channels simultaneously, or does it output data sequentially?

Thanks,

Hi Don,

When using the FMA co-pilot with a PCM Futaba receiver, it is recommended to use a servo buffer 605SB, this is placed on the elevator channel (3) and essentially adds a delay into the Futaba receiver output.Futaba receivers are unique in that they output channel 2&3 simultaneously instead of serially and the co pilot computer uses the added delay to allow it to capture the channel information.Without the servo buffer in place with Futaba systems there will be erratic servo behaviour.

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.

Thanks for the reply. You mention channels 2 and 3 being output simultaneously, but I'm concerned with channels 1 and 2. Do the receivers also output 1 and 2 simultaneously? Do they output all channels simultaneously?
