Global Drone, Skull Drone or GW008

Whatever you want to call it there was quite the buzz on this little guy all over YouTube so as soon as Banggood restocked (Recieved 11/28/16) it I ordered and just as my luck would have it, doesn't bind to the (green) option under CX10 protocol; I searched the forum for further info on this quad and there is not that much. I will try and get some pix up tonight.

It gets great reviews on the website and on the R/C forum but to me it is uncontrollable with the stock transmitter. Maybe I am just to spoiled by the great control ability the the devo gives. I will give it two thumbs up for looks though and I am very much a fan of the speed from this little guy.

For some cons; using the stock controller in low rates the aileron is almost non existent and will not help if you get into trouble in a sharp turn. In mid rates the quad flys very well except for the throttle and its quirkiness hard to keep it on any horizontal plane its always up or down adjusting for any particular level of flight. (again maybe its me being spoiled). Cant fly with high rate at all indoors dont ask me how I know quad was all over the place (mostly on the ground after a crash)

I will do my part and try to get spi for this and the other three quads that I have that didn't bind; however, its gonna be awhile ordering a analyzer from china. So to anyone that can help I'll be needing it in the near future

I am also curious if the chipset used in the OEM transmitter is what is the determining factor in which module installed in our Devo's that will control the R/C vehicle? At the moment I only have the nrf module installed in my devo.

The chipset in the OEM transmitter has these markings on the bottom

FJ-SCMK-1
And on the top: NST LT8910SSC

Vcc, ground, miso... are clearly marked so when my hardware (analyzer) gets here I shouldn't have any problems attaching correctly to the tx but as I said earlier this is all foreign to me so I'll be looking for help any and all are appreciated.

Hi there, got two of these, both with the same board. (Different coloured remotes, tho).
Would be great to be flying these with the Devo. Potential great flyer but the #(&*$ original remote...
Any progress yet?!

I got mine yesterday and it wouldn't bind to the deviation Hui Ying protocol (CX10 Green). I opened everything up and the FC board is still printed HY-853. The TX is 851? I'm puzzled. Note the TX chip size slot in the board. Heh. Woulda been a much easier SPI capture, so I was disappointed to see that. It's now a direct connect between the MCU and antenna/crystal oscillator. Toy quads. Start out with all the bells and whistles and slowly whittle everything down to the bare minimum. Just a few months after yours it's now bare bones. 3 motor wires disconnected lifting the FC up with practically no force. That's a new one.

I'm no electronics guru. I can hook up probes and the logic analyzer to MCU pins and see what I get. There's less separation now without a TX chip going to exact pins. Not sure if the data will be mixed with other functions. Might be better to go to the RX.

Here's a pic of each. Humanntrst, this is the sort of detail you need in your pics if you want anything done here. I'd really like to see traces from the TX chip to the MCU. So can you get a detailed shot of the other side of the TX board, and which traces are MISO/GND/Voltage? It's an awesome little quad, but the stock TX is easily one of the worst. The controls are so stiff and non-linear. Feels like 2 pop-o-matic bubbles. I've posted this on RCGroups as well. We'll see if we can get somewhere. Still waiting on a new Yi Zhan X4 to do SPI captures. I broke the first with a cheap rubbish soldering iron. Got a great one now so I'd like to work on this.

Thanks for the quick reply goebish. Appreciate it. Sucks about the quad though, cos the TX is truly awful. I have the gimbals from the broken Yi Zhan X4, let's see what happens when I solder them in .

Do you know if any vendors will source early versions upon request? Prolly a silly question but just thought I'd ask. I'm a bit over getting quads that aren't/can't be deviated any more. At least I can now start picking up new models. I suppose they're the most likely to be deviated at some point. Thanks again.

Oh.. ok! Happy it peaks your interest. Ordered December 1st from Banggood. I'm more than happy to pay for the donor. No need for personal details. If you use bitcoin PM me an address. Not sure how often you actually fly but you'd really like this one. Unlike most I think the look is errrr....10 year olds would love it I got it based on opinion.

I've written a LT8900 emulator and I would like to see a dump of this little guy to see if they have activated any of the 8910 additional feature. Let me know as soon as you can do a capture.

Ok, I've (back)ordered one, let's hope it's the same version.

Hmmm...re-order It should be the same. Having said that, I just got my 'new' Yi Zhan X4 and and it's a green board that binds to my Devo 7e! Heh. They did send me a non-LCD version, so maybe that model isn't updated to the REV:04 FC. Fingers crossed.

Cool. Thanks for the hard work. Edit - Didn't know how it worked. Sent $20, looks like it goes towards next month. I will definitely continue supporting each month cos deviation will benefit me for as long as it's going. I'll have to lower my monthly pledge, but wanted to give you $20 first. Hope that's ok.

Note that I can't promise anything and I already have 4 or 5 protocols to implement before I start working on this one ...

Of course. Anything on top of what I already get with deviation is just a bonus. Are any of those protocols the new JJRC H20/30 mini? If no-one's working on those I'd like to at least get the SPI captures (if possible). I don't need to worry about the Yi Zhan X4 now, but I will still finish the captures (quad wont bind but the MCU still operates)

Sounds busy! So these new quads. The latest gimmick is altitude hold. Given we're using Devo's without sprung throttles (by default), can that function be turned off so we can still look forward to buying and flying these models. I haven't bought a single one yet because I just don't think I could ever get used to a sprung, centered throttle. I also have no desire to use altitude hold on a small quad. A big expensive one, yes, but not fun little flyers.

The H30 mini binds to the H20 mini controller too. And vice versa obviously. So 2 birds...

So how would alt. hold function on a Devo without a sprung throttle? Do you have to mod it so both sticks are sprung to fly them? Or is 0% throttle effectively the middle? Push down throttle to 0%, quad hovers? Sorry, last question. I'll let you get back to work now .

As I stated I've got two of these little skullys, wouldn't mind sending one of those plus the transmitter to you, Goebish. I'm living in the Netherlands. Just let me know.
