Can't get any servo movement - they make noise but no inputs from transmitter. Here is what I have done. In Spirit software: Updated to latest firmware 3.7.1 Set receiver protocol to PPM ??? Receiver did bind to transmitter ESC throttle to AUX1 ESC additional power to Aux 2 ESC RPM ??? don't know where this is to go From the RP3-H 4 wire connection to Rud channel Neg to neg ??? VCC to pos ??? rx to signal ??? From RP3-H tx wire only (white wire) connect to top pin only at elev/pit/ail ??? Have Hobbywing V5 telemetry but not worried about that yet but it will plug into ST-1 (satelllite connection) Is this information documented anywhere? TIA for any help, thank you. |

The manual is kind of a mess on this topic tbh. There's the main wiring page which isn't complete, and then there is the crossfire page which isn't linked anywhere, and the governor page which describes the rpm wiring. In any case when you flash your receiver you choose what protocol it outputs, you likely want crsf for telemetry support, but it can also do sbus. Setting to PPM makes no sense to me. See these two pages: https://manual.spirit-system.com/index. ... sFire_CRSF https://manual.spirit-system.com/index. ... ng_example Or if you want to use sbus output for some reason: https://manual.spirit-system.com/index. ...

Thanks for the help I was pretty close.. the wiring for the RP3-H is AS FOLLOWS: RUD input - "S"= white wire; "+"=red wire; "-" = black wire ELE/PIT/AIL input - "S" = green wire I just need to get the governor working now. Going to solder up a connection from ESC RPM to middle pin on EL/PIT/AIL just below the green wire and hopefully good to go. |

Just a tip, if you use the standard 3 pin servo plug (JR, the one that is likely already attached to the rpm lead), you can easily use a needle to lift up the plastic tab on the open side of the connector and slide out the wire, then push it back in where it needs to be. This way you can make it into a single plug with rpm and crsf rx. |
