    Hi,
    i’m currently stuck at setting up the servos – in a weird kind of way:
    Can’t set the servo midpoints an throw limits through Betaflight, no value i input (and save) changes the position of the servos in any way – and yes, i’ve enabled live mode.
    I’m running Betaflight Configurator 10.4.0, and i’ve so far tried the 3.5.4, 3.5.3 and 3.4.1 firmware versions.
    The servos work as expected when the transmitter is active.
    Has anybody experienced a similar issue?
    Regards,

    Steffen

    Hmm,
    strange, although i applied the resource mappings the servos are actually numbers 5 and 6 … i don’t get it!
    Think it would be nice to get an updated version of the build video with the new FC, maybe there are other gremlins still lurking.
    Cheers,

    Steffen

    Ok,
    with the latest Betaflight firmware the servo setup finally worked more or less as expected – the servos are #4 and #5.
    My current settings – be aware though that i haven’t had the time yet to fly the bicopter – are printed below, some values differ from the settings that David posted, e.g. the mixer is ‘BI’ instead of ‘BICOPTER’.
    Cheers,

    Steffen
