    Since Marko is interested.. Here is my first LOS(Line of Sight) flight.

    Realized i did not do a full video overview of the semi-finished quad yet.
    So here it is :
     


     
    Edit: And the very first decent in flight video.
    Camera is still slightly too much to the front, resulting in a minor yaw offset. But will be fixed.
    Also: BEWARE, LOUD NOISE!!!

    Well it's flying! Got a total flying time of about 14 minutes now, and my first crash
     
    Finally felt confident enough to fly it higher than 40 centimeters today. So it was at about 3 meters and easily hovering towards me when one of the cheap rubber bands that keep the propellers on popped off.
     
    Flight lesson number one: A quadcopter missing a motor/prop behaves like a brick.
    Flight lesson number two: Bricks dont fly well.
     
    result:
     

     
    So i was bummed, but then the urge to fly tomorrow came. So i dove into my drawer, found an old 10mbit network card, stripped and cut it, and voila: new arm base Its even stronger than the one i built originally, and i pushed the motor mount a bit towards the struts. Also, its the forward arm, so that now has a unique color.

    Ok, i really dont know if the picture is accurate, and motors and props are included. Because the description only says "Flight Board with XXXX Sensors".

    Supposed to have an STM32 controller, but the picture shows an AVR. If its indeed an STM, those are pretty common and easy to program. Bit faster than the avr as well, and 32 bit. And seems on the picture that like most of the pins are broken out.
     
     
     
    This is apparently the STM version
     

     

     
    But for that price, and free shipping, im going for it. Just ordered and see what arrives
    Will update here ofc.

    I think I am done with the layout.
    To make this board more versatile, port P1 is connected to the header, so instead of USB->MIDI, this board could also be used as logic analyzer or USB->Power Board/Relays, etc.
    There is a programming header, BSL header, 3 LEDs (one USB power and two general use,) opto isolator and buffer for MIDI In and Out.
    The two drill holes on the left can be used for wire tie, in case wires are soldered directly to the board.

    The phone was too far too the front, so it was heavily correcting for the imbalance, as wel as correcting for level. That does not work Next attempt soon with camera in the middle.
    And got my eye on a 35 dollar 28 gram HD camera, from the mentioned Chinese supplier (im not an ad service )

    But only the arm damaged, and already got a better design. So should be a 30 minute fix

    Not much info yet, just the price; a $4.99 kit. :clap:

    EDIT1: Found an LCD boosterpack for this board http://www.kentecdisplay.com/uploads/so ... ide_03.pdf

    EDIT2: by the name of the boosterpack It looks like there will be one of the LM4F120 Series

    Im using these motors: http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=5358
    Only about 10 gram, dirt cheap, and working pretty well so far. Just make sure to re-tighten all screws before flying the first time.... In my 3d flight one of the motors came out of its mount costing me a prop.
     
    Right now im using a 850mAh 2s lipo, but i already have a 1500mAh 3s here to mount, only need proper connectors. The extra voltage from the 3s will give it an additional 75 gram lift per motor, for only 100 gram extra battery weight. And just within specs. The extra mAh is because it will empty faster with the increased power, bit of compensation.
    But still need to test that setup, so dont take my word for it yet.
     
    I also switched to a new board. Crius multiwii. Its still fully programmable with arduino/multiwii, but the board is configured for easier connection of the esc's, RX channels, and all other pins also nicely broken out.
    PLUS it has on onboard gyro, accelerometer, compass and barometric pressure sensor.
    I was originally only looking for the extra sensors. but when i saw that complete package for only 31 dollar, and a total of 17 gram, i was sold. The 0.2 version i found is sold out now, but the 1.0 is available for 38 dollar: http://www.rctimer.com/index.php?gOo=goods_details.dwt&goodsid=761&productname= Same precessor and sensors, just slightly different board layout.
     
    Finally, i started work on the lights. I took the shiftregister module i created for the MSP430 porsche, converted that code to arduino, and slapped it into the Multiwii main routine (not the flight loop ofc)

    Aaaaaaannnnnnddddd...... A flight video!
     
    I was trying to stay low because i was testing new rubber bands for the props, at one point you see one snapping. Also trying to stay low for the camera ofc.
    But it gives a nice impression of what it can already do.

    Nah. A motor was damaged (caused the crash anyway), one arm was bent/fractured and 3 props with missing blades. All the important stuff survived. It was flying again later that weekend.

    Brilliant work! That's nice stable flight you have there.
     
    I would forget using prop savers. You are hanging the weight of the quadcopter (/4) on those rubber bands. Use fixed hubs and buy shares in a prop manufacturer. Trust me, I have. :?
     
    And be confident and get some height! You'd be surprised at how much ground effect there can be.
