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

The chipset in the OEM transmitter has these markings on the bottom
( Fanjie )
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.

Would be great to be flying these with the Devo. Potential great flyer but the #(&*$ original remote...
Any progress yet?!

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.

That makes a lighter, less complex and probably less expensive design, which is a good thing, especially on the RX, but that makes our lives harder
The RX part has "PAN" in the marking, so it's probably XN297L compatible (Panchip), one would have to try to sniff the TX "in the air", with an Arduino + nrf24l01, not that easy without knowing any parameters (address, bitrate, frequency, whitening ...), and/or use a SDR solution ...

Sounds like an interesting challenge

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.

I've never used bitcoins, but if you want to show your support, that's here:

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

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.Humanntrst wrote: 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.

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.Ok, I've (back)ordered one, let's hope it's the same version.
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.I've never used bitcoins, but if you want to show your support, that's here:

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

The H20 mini should be easy to add, looks like it's using the same protocol than the H20 but it needs an extra arm channel, I'm looking for some dumps, please post here:

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

Cool, give me a spi capture with the arm flag, shouldn't be long to add them

Most of them won't arm until you set throttle stick to middle position.
