    Hi fellow explorers,

    Just finished the babytricopter build. But had 2 evenings of frustration…..

    I used an devo rx716 very small pppm receiver. Hooked everything up with the standard electronics kit for the babytricopter. Connected to cleanflight, everything works except the reciever input. Tried uart1, uart2, uart3. Set the rx output in the port tab. And set ppm in the receiver tab.

    Am I overlooking something…..

    The reciever binds (solid red light). Tried normal bind and fixed ID bind.

    Maybe the rx has a malfunction or its a setting in cleanflight.

    Forgot to mention, the green led on the FC is solid, the bleu light (and beeper) are flashing.

    What protocols does the RX support? Tried to google but couldn’t find the info.

    If it’s PPM as you said it won’t work on the UARTs as it’s not a serial protocol. You need to connect it to PPM input and configure the FC for PPM input, see https://youtu.be/-eAeA5McNi4?t=520.

    Okay you tickled my brain a little 🙂

    The protocol for the rx is ppm.

    I think the problem is that I soldered the rx signal wire to ‘r1’ (just followed the instructionvideo blindly) but it should be soldered to port ‘6’ because it is ppm protocol.

    is that correct?

    Yes, the pin labeled ‘6’ should be correct for ppm.

    Mine came with all white wires. But see attached picture from another forum for the ppm pin out. I used the ppm output.

    I don’t know what txd output does. Didn’t connect that one. Couldn’t findout what the supposed to do on the walkera site / forum’s or manuals.

    thanks
    so all works fine with that receiver and non walkera fc?

    i plan to use devo 7 and this rx716
    with cc3d board flashed with betaflight

    Yes it’s just the ppm signal that it needs. Also used it on other builds no problems
