    EZUHF JR module and Taranis

    Apologies, if this has been covered before.

    I now have SBUS firmware running on the EXUHF JR module in a Taranis, and the 4ch EZUHF receiver is also running SBUS firmware.

    The receiver is connected to a Pixhawk using an SBUS lead, Pixhawk in in fixed wing mode with servos being powered by a 5V BEC powering the Pixhawk servo rail.

    I have noticed something on the Elevator control, when the throttle is at 0, the Elevator servo operates normally. As you increase the Throttle the movement of the elevator decreases. Occasionally a glitch is observed.

    It seems like there is slight channel crossover between channel 2 (Elevator) and channel 3 (Throttle). Has anyone else come across this and found a fix?
    This was the same when the PPM firmware was installed.

    Taranis is running firmware 2.1.9 due to an issue with 2.2.0 There are no mixes set whatsoever in the Taranis transmitter.
    Exactly the same on two separate transmitters.

    Thanks in advance.

    Hi how many channels are you using and did you also set those channels in your Taranis? And pls use the ppm firmware. Sbus is only for small racing quads that don't go out far.

    Thank you for the reply

    The Taranis is set up for 1-6 channels
    EZUHF TX and RX are also set up for 6

    OK.I will reflash the firmware back to PPM. Will that not cause twitching due to slight differences of Taranis frame rate?

    Can you set both taranis and ezuhf up to 12 channel? Try and see if that fixes it.
