    Networkm0nkey's Build Log - AQ Cyclone v2

    Although I'm fairly new to the RC world, I have decided to try and build a nice quad while waiting for spring and warm weather to arrive. Since I do want to transition into some better AV and eventually FPV, I selected the Cyclone frame since it large enough to handle a GoPro, can setup in several different configurations and has parts that can be replaced fairly easy.

    So here is what I am planning on so far:
    Frame: Cyclone v2, X format
    Brains: AQ 2.1 Kit
    Transmitter: Spektrum DX8
    Receiver: Spektrum AR600 Sport DSMX
    Motors: BP A2217-9
    Props: APC 10x4.7
    ESCs: HobbyWing FlyFun 30A
    Battery: Hyperion G3 Vx 5000 mAh 3S 11.1V 35C
    Altitude: MaxBotix LV-EZ0
    Camera: GoPro Hero 2

    Further down the road:
    Wireless: Most likely Xbee 900mhz
    GPS: Maybe
    FPV: Probably try for a 5.4ghz system

    First good news, according to FedEx, my frame and mega kit were delivered today and are waiting for me to get home from work! Now while I work on putting the all headers, etc. on the Arduino, hooking up the shield and sensors, I can decide on the rest of the parts.

    Looking forward to the build, trying to remember to document the process and joining the community here.

    Cheers

    Seeking feedback on selected parts list

    Hi All,

    I was hoping that someone with a little more experience could comment if I am on the right track with my parts list. At the moment, most interested in whether I have a good motor/prop/ESC combination, but any other comments, questions or advice would be great as well.

    Here is the current part list:

    FrameCyclone v2, X format
    ControllerAQ Mega 2.1 Kit
    MotorsTurnigy 2217/20
    ESCsTurnigy Plush 30A
    PropsAPC 12x3.8
    TransmitterSpektrum DX8
    ReceiverSpektrum AR600 Sport DSMX
    BatteryHyperion G3 Vx 5000 mAh 3S 11.1V 35C




    Thanks

    I have pretty much exactly same components on my bigger quad.

    One thing about the motors, you will want to put threadlock on the screws holding the axle (otherwise the screws will undo themselves and fly off and your quad will come down).

    Publishing individual build data in this way is an excellent idea and deserves a separate sticky thread where we can all post our data - how about it mikro?
    As well as pid settings a flight video would be good to demonstrate the achieved stability.

    FPV, remove bullets, testing new landing gear

    Removing bullets
    So I finally decided to rewire my quad by removing all the bullet connectors between the motors and the ESCs. I had avoided this in the past since it would make it a pain if I had to unsolder everything, every time I needed to replace the arms. However after a crash a few weeks ago that almost chopped my motor wires off, when I crashed and the motor mounts slid down the arm, I decided to just run the wires outside the arms. Now that I am doing that, I can remove the motors from the arms without having to unsolder everything.

    One nice side effect of removing the bullets, was the weight, all the bullets and the solder in them to hold in the wires added up to over 40g. I also was able to shorten the wires running to the ESC, since they now run straight from the motors back to the ESCs, saving a few inches on every wire.

    Adding FPV
    Friday, my order from Hobby King finally arrived and I now have their cheap 200mw 5.8ghz video TX. I spent quite a bit of time yesterday getting the MAX7456 OSD wired in, getting a cable setup for the GoPro2 to hook into the MAX and video TX. I was able to get everything temporarily mounted on the top side of the Battery plate, but had to switch out the 1/4" standoffs with 1/2" standoffs in order to make sure that there is enough clearance.

    So far it is working, but do have some issues with the video signal dropping completely for 1-2 seconds at a time. This could be due to having too high of voltage on the video RX, using a 2S lipo at the moment, but it calls for 5V for the RX, so need to take care of that. Might also need to adjust the channel on the TX/RX and add a 10K resistor to the MAX OSD, instead of the plain wire that is running between the 5V+ and reset.

    Here is a test video in the basement.

    Note: The GoPro was not recording, so the camera shuts off partway through the video. The quad is a bit unstable after removing bullets and adding the video gear, it needs some more tuning, but that is fine since I can now change the PIDs via the OSD menu!!

    New landing gear
    I installed some new test landing gear that Mikro sent, so far I love them. The new landing gear and nylon screws/nuts almost cut the weight by 50% over the original ones. Saves almost 20g per gear. Now I need to get outside and fly, to see how well the new gear holds up.

    The need of 5V seems to be a typo on the product page as it says otherwise (6.5-12V) in the Rx data-sheet (last page) and personally I already powered it even with a 3s LiPo without any problems.

    Yep, 12v is correct for that system. You probably are also seeing close phasing problems when a transnitter and receiver are so close. When they are farther apart, it will work better.

    Cheers, Scott

    Thanks, confirmed that up to 12V should be fine for the RX, went ahead and picked up a AC adapter so that I can skip the battery when close to an outlet.

    Scott, think you are correct with the RX and TX being too close together. I moved the quad upstairs and ran the RX downstairs and saw much less issues with the video dropping out, once the quad was back downstairs, then it had an increase is the video dropping out.

    Any issues with wiring the TX direct into the battery feed on the quad, using a 3S, so the 12V should be right on. If that should be fine, I'll probably wire in a connector so that I can kill power to the TX easily if I am not going to use it.

    Thanks,
    Matt
