    The 8Ch Turnigy 9X receiver doesn’t do PPM, only parallel PWM.
    Disable PPM mode and see if that does the trick 🙂

    Any special precautions for avoiding taxes etc?
    I have never ordered anything from Banggood, is it the same thing with them as with HobbyKing? i.e. hard to avoid beeing hit by customs fees etc?

    @Terje: Exactly right 🙂

    I was so lucky that i had unknowingly had a CPPM receiver laying around, only 6 channels though, but for an acrobatic model, i can live with it 😉

    You shouldn´t use Hot glue for Depron, use UHU POR.
    It´s actually really nice to work with, and almost as fast as hot glue.

    Are you saying that you CAN get the Depron in Norway or not?

    I´m using one on UART1. Only drawback is that I have to unplug it if I want to connect to the board using the USB-cable.

    I use UART2 for Blackbox, that´s why I don´t want to use it for OSD 🙂

    I´m not sure if you could go soft_serial for the MinimOSD, I know that you can´t do it for the Blackbox

    EDIT: Don´t forget about an 5V FTDI adapter if you don´t have one.
    You need it to change FW/character set and change the configuration (What you want to be displayed on the OSD)

    @lauka: I am sorry about causing confusion, but I think that the labels for the gyro axis is misleading, that axis only shows the PIDs. (still learning the tools!)

    How to test motors for vibration, just run them with no prop attached and “feel” the vibrations?

    I have actually not balanced the props, but they are high quality APC props, so I don´t think that they are that bad.

    Based on the roll values from the blackbox I lowereed my PID – I from 0.035 to 0.015 which seems to have made things at least a little bit better.
    How low can you go? 🙂

    Did a blackbox for the behaviour.
    Input please! 🙂

    @Terje: I would be thoroughly impressed if you managed to manufacture an integrated Micro Tri frame using nothing but a 3D printer, plywood and a coping saw 🙂

    Of course, you can come a long way with those tools, a 3D printer is @ the very top of my wishlist, but I haven´t allowed myself to buy one yet.. 🙂

    @LeoTheHuman: If you used a hollow rear boom that is circular instead of square, you could use a small servo on the frame to twist the entire boom, complete with motor and prop.
    You would have to find a good way to create some kind of journal bearing for the rear boom and be creative about mounting the motor to the boom 🙂
    See attached picture 🙂

    @LeoTheHuman: Doing a micro board with integrated PDB may be good enough perhaps?
    Hand soldering the PDB components are not a challenge like the USB-interface and the Gyro/Accelerometer would be.
    If someone would come with a suggestion for a board outline I´ll fire up Altium and get started.

    I could make a try to do the design for a micro integrated frame if @David would be kind enough to support us with prototype manufacturing. (I know that he has connections in that line of business…)
    Since I´ve only been flying the normal V3 integrated frame, I have no idea what the requirements would be for a micro frame.

    Maybe components could be distributed across two boards connected with SMT sockets/headers, or flex if that would be a better option (my own experience with flex boards are that then are quite wulnerable though..)

    @LeoTheHuman: Of course we should have a trouble shooting guide.
    I guess we could start a new thread and ask @David to make it a sticky in both the V3 and the Mini sections.

    @LeoTheHuman: The Micrel MIC5207 actually DO have reversed voltage/battery protection.
    The BEC 5V and the USB 5V feed the same voltage regulator through a Schottky diode.

    @pclark531: Thank you for testing the reverse battery protection out for us 🙂
    When you write “I am not getting power to my receiver” is that a typo, or are you still NOT getting power to your receiver?

    Hi.
    Should there be a LED that lights up on the receiver, or how did you reach the conclusion that it doesn´t get any power?
    Make sure that the CLI argument feature -RX_PPM is set, just to make sure that you are actually expecting Parallell PWM RX input.

    Does the receiver work with other ESCs/BECs and servos etc?
    Is it properly paired to the transmitter?
