| Post subject: | JR in pwm mode |
Hi, I`m just wondering if anyone is using a Spririt FBL when using a JR XG14. On the TX I have it set to one servo as per the Spirit instructions. The RX is a RG612BX. Ive bound it so the XBUS is off, and not taking up channel six. The Ail Ele Pit servo`s work for cyclic but not for collective. The pitch is seen working on the TX monitor with the throttle, and the pitch channel isnt mixed with anything else that I can see. In the software the RX is PWM, I get varying results when setting the TX to CCPM120 three servo or playing with the correction mixing in the swash mix. I ve read that some people have had success setting the XBUS on and going that way but I thought it should work as a PWM Any idea`s? Thanks Dean |

Hi, if you use XBUS [mode B] (single line connection), then you have to select SRXL/SUMD receiver type in the software, else it can't work. If you are using normal receiver with 3 supplied cables, then it is always PWM connection. Which one do you wish to use? With XBUS you have to change channel mapping (I recommend in the TX if possible). Channel numbering does not matter (they are different between unit and JR) - important is that the movement is correct. CCPM 120 should be always disabled in the transmitter (no mixing) |

Thank you for your reply, Although the receiver can be used with the XBUS as a single line connection , it`s currently setup as PWM with the cables so the XBUS is disabled. The CCPM in the TX is disabled with no mixing. I just wanted it to act as a standard receiver. This method has worked fine when using a K/bar gyro although not with this particular RX. The servo monitor in the TX recognizes the pitch channel as working and also in the software, the green pitch graph moves, but no servo movement apart from cyclic. If I enable CCPM in the TX although it should be H1 or one servo normal, then the collective starts to work to verify the cables are ok but servo throws are all out of whack The cyclic movements are all working well when setup via the instructions but no collective movement |

When in the `servos` tab and select `servo travel correction` everything works as it should |

Then it is easy, your Gyro Gain is negative, which means that the Rescue mode is activated all the time. You have to just change the value and it will work. So practically there is no real issue. |
