For SBUS with the small spirit units, will any SBUS inverter work or does it have to be the "S-BUS adapter" from spirit? Thanks |

Which spirit? Only the original red spirit needs sbus inverter afaik. |

The original red i mean (small one). I know it needs an inverter, but I wonder if I can use any inverter or if it has to be original spirit inverter. I would like to think that any inverter works, but then I read about sbus problems with the later frsky receivers and thought that perhaps there is more to it then just inverting the signal. like different signal levels etc. I need to buy an inverter and the quickest option is just to by a generic inverter from the local store. |

I would expect it to work with any inverter. |

Hi, any inverter should work, but we recommend Spirit for safety reasons. It has better electronics (real logic inverter with LDO) unlike other cables. |

Thanks! So I bought a generic sbus inverter, but in the spirit setup the channel mapping tab it is all messed up. Channels mismatch from the transmitter and the center point jumps depending on what function I am trying to map a channel to. I wonder if the problem is in the SBUS inverter or in the configuration. Can you tell me if I am doing this wrong... The heli is a small "beater" with a spirit (non pro) and has been working perfectly for a long time with a jeti receiver. Now I am converting this to frsky (yuck! i know) just so I can use it for occasions when it is impractical to haul the jeti transmitter with me. Since the gyro is perfectly set up for the heli with Jeti, I made a model memory in the frsky tx that matches up all the channel mappings and PWM signals (center, end points and directions) identical to my Jeti. I then changed the receiver type in the configurator from Jeti EX-bus to SBUS and then plugged in the new frsky SBUS receiver with inverter. Should it work? It behaves as if the sbus signal somehow is corrupt. Some channels goes through as expected. Some has to be remapped/inverted, and some are missing/inconsistent. I expected to se working mapping and directions with minor adjustments required for center and end points. Would it be any different if I used the setup wizard? Receiver is frsky rx4r. Spirit firmware is 3.2.1 |

my bad  . I had not set the ranges correctly in the transmitter. Seems that made the gyro unable to read the sbus signal properly. With this corrected it worked after swapping channel 1 and 3, as well as reversing some channels.Still is it ok to swap receiver like this without redoing the wizard? |

Yes, you can swap receiver without any other change. |
