[NSRCA-discussion] Expert Electronics' F650 Negative shift RX

[J.Oddino]

I'm pretty sure it won't work.  The sync pulse is the wrong polarity with respect to the servo position pulses in the 9Z.  Just inverting it won't work.  I can't imagine why they did that.  Interestingly enough, the Berg receiver figured it out.

  Hello Incheol,
  I assume that the F650 does not work with the synthesized 9Z TX module.
  Try it with a non-synthesized module and it will almost certainly work.
  This would not be the first RX to show this "feature".
  I am told (though I have never tried this) that if you unplug then re-plug the 9Zsynthesizer module
  while the TX is powered up that those same  RX es will work with the 9ZS module.
  All the best,
  Dean

    Has anyone tried Expert Electronics' F650 (Horizon part number EXRR6501) with Futaba or Hitec transmitter(s)?
    This is JR Propo's R610 receiver in negative shift.  Very good and cheap receiver.

    So far, it works good with Hitec Eclipse.  It does not work with Futaba 9Z on PPM.
    Apparently Horizon did not know until today that this receiver does not work with 9Z.
    If anyone tried them, would you please let me know?
    Thank you,
