Trying to get started

    Hi Guys,

    Over the last months I have been thinking about getting a quadcopter. I have been going through various internet sites and discussions. YouTube is a good way to get acquainted with this world as well.

    So the biggest thing to tackle was: Am I going to get a RTF Phantom which works pretty much out of the box but is pretty limited if I want to get enhancements. Or do I get a DIY frame and build from there.

    Well in the end I got a DIY already built from somebody that wanted to stop the hobby.

    I got a Carbon frame with NAZA Lite, DX6i transmitter and some spare parts for the frame and a couple of sets of props.

    I have never flown a quad. So I am pretty anxious and really want to be sure I fly in GPS Attitude to get stability.

    So I put in the battery. I can hear the quad firing up. I can see the NAZA flashing yellow. Now they have told me that I have to switch more or less 6 times from Manual to GPS to get a constant yellow light. After that I need to do the movements to get a green light. Without that I shouldn't take of of course.

    Now, the problem is that the light keeps flashing yellow, no matter how many times I switch from GPS to Manual. Looks like I am end of the road here. Must be something with the transmitter.

    How do I know that my transmitter is connected? What could I do in this case. Or maybe it is something else?

    I am sorry for these novice questions.

    Thanks!

    Well, I think you see the wisdom of starting with toy quads or an RTF....

    If things are not working your only choice is to troubleshoot at the component level. Or, more likely, to ask the guy who sold it to you whether it actually works or not - and ask him how he got it to operate.

    However you fly, the Compass Calibration is important - that's what you are describing - that you cannot seem to calibrate the compass.

    Firstly, sometimes the switch needs to be thrown back and forth as many as 10-12 times before it goes into compass mode.
    Check out this video:


    If you want to make sure the basic RX is connected, you may be able to go to ATTI mode and then arm the props (don't fly, but just arm them to see if the TX and RX are talking).....

    Other than the basics, you'd have to become familiar with the TX setup and check all the various switches to see if they are set for the proper channels, etc.

    Thanks for your reply.
    I have done what you said. I have put it is attitude mode and try to arm the props (the two sticks below right and left corner). But nothing happens. So I think that the DX6i does not have any contact with the quad receiver. Should I bind it again? Can I do that with the quad assembled or should I take of the receiver?

    Thanks so much in advance. Paid some money for this thing and I cannot get it to work... ggrrr. But i am sure I will get there.

    Well, the good news is that you will learn a lot.....probably time to look at instructions and files at:
    https://sites.google.com/site/spektrumradioprogramminghelp/spektrum-spm-files/nazam-programming-spm

    I don't think you have to remove the receiver at this point, assuming it's only a software and binding problem.
    I also think you can try to NAZA assistant and see some of what is going on.

    TX programming is a PITA. I always feel like I am taking a step back to the early days of personal computers, when I spent all my time trying to make my computers talk to the printers....

    I am already a step further. On the DX6i the model was setup wrong! I set it to the correct model and it seems to have signal.
    The NAZA flashes on green en two red and it repeats. Now I have to find what that code is...

    Thanks

    Got it working. Naza light is constant green now and I have powered up the propos and they go like hell.
    The only problem is that I am a bit chicken to flight this thing now.

    Great - do it in a nice open area!

    Also, connect up the DJI assistant and check all the settings. This will at least confirm some parts of the setup. Also, if possible, make sure the course lock and home lock are enabled and assigned to a switch. No big deal if not - I didn't use them at the start.

    Thanks for the advice! I will do.
    But I have a Mac. I have discovered they also make the software for Mac OS. I just need to buy a flipping USB cable with a small connection point.

    Feel like a 15-year old with a new toy (but I am 45) :)

    What do you fly?

    That's a nice quad - setup for FPF or other cam uses where the cam can be up front.

    I fly lots of various models - mostly toys, but I just finished reviewing the Phantom 2 Vision + here... I didn't end up buying it because I don't have a need for taking a lot of video right now. I prefer experimenting with different cameras, etc.

    The quads I actually fly are the Phantom 1 - which I love for fiddling around with. But when I want to have some fun in my yard and street, I fly the v262 - that thing ($65 now on Amazon) is really a lot of fun.

    I like my Hubsan Quads X4 also.....and I probably learned more with my $35 Syma X1 than with any other quad - but don't have it any longer.
    I have a micro-qbot on the table which I use with the 9X TX - to learn TX settings, etc - it flies without much self-leveling, so it's another good one to learn on.

    In the next year I'd like to get (or at least test) the Eye One Extreme, the Skyartec Butterfly, The Parrot BeBop and perhaps put together a video and photo platform for myself....or buy a larger quad like the upcoming http://flyingeyes.com/

    Looks like you have some nice plans for next year!

    I have ordered the JXD-388 from Banggood to have a small "toy" as well to learn. Ordered it two weeks ago, I guess I need to be patient with Banggood. It was only 30 bucks! I wonder if I could fly it with my DX6i.

    Update: I have got it in the air for the first time!

    It was a bit windy but I could not wait for the first maiden flight. I loaded two Lipo's (2200 Mah) and went out in the field.
    Problem with this quad is that it actually has no landing gear. This means that you need to find a good flat spot with no grass.
    No grass means on the road (tarmac) which is not such an intelligent plan for your first flight with a carbon frame. So I took off in the grass anyway. Grass got in the props and the axis (**##@@*). Got everything out and started on the quad on the road, one meter from a grass field. As soon as it took of I hovered to the grass field. It worked.

    This thing is really stable with the Naza Lite. After a couple of minutes flying I got the hang of all the controls: Yah, forward, backwards, to the sides. The only thing that is a bit tricky is to remember what is front and what is back. I even did some fast overshoots! Landing is easy in the grass and with the Naza is stays put!

    I have noticed that the Lipo's only last for about 5 minutes before the red light start flashing on the Naza. I do not know what the settings are for low battery in the Configurator. I ordered the USB cable and I will have a look in a few days.

    When I reloaded the batterie I could get 1000 Mah in the 2200 Mah batteries. So it lost about 50% of its charge. Maybe the settings are a bit too cautious?
