V252 "Pro" different protocol?

Ugh... I just received the WL Toys V252 I ordered (Hubsan X4 clone with transparent body and lights) to fly at night.

They have been hard to come by as I guess Hubsan has been filing injunctions and stopping their sale everywhere. Anyhow, the one that arrived is a brand new "Pro" version that is much uglier looking, and only lights up a little on the bottom -- top is solid metallic paint. It has some cheesy pinwheels for feet. Looks like this:
V252

Anyhow, I thought perhaps all is not lost if I can order a new body shell for it somewhere so I figured I would fire it up quickly. It does not bind.

I tried the RTF tx it came with and it does bind automatically after about 10 extremely piercing annoying beeps (no usual throttle up/down). I'm wondering if they changed the protocol in this revised v2xx model to something else Has anybody else tried one?

Definitely not interested if I have to install another module just for this... everything else I have is Walkera or nrf24L01.

Do you have your nRF24L01 module isntalled in your devo ?

Yes indeed My V222 and JXD 385 both work great with Devo 10.

I seems like this "V252 Pro" is a pretty big overhaul if they changed the board. I wouldn't have thought the RX/protocol would be an issue as much as changing the physical appearance if it is because of Hubsan lawsuits. Just adding the spinner feet doesn't seem like it completely sets it apart.

I gave my 911 away as it wasn't my cup of tea, but now that I think of it the remote and beeping is reminiscent of that.

Maybe they are using their new "KN" protocol as well as for their new Power star helis.... Yes Wltoys have a fourth new protocol but it's surprizing for me they used it for the V252 pro. For example, for the new incoming V323, it's still using the "V2x2... Well it's clear that WLtoys are completly illogical

After FlySky, HiSky, "V2x2"<=> "LG", i.e. the name of their rx board designer subcontracter, the new compagny acronym used to design their new protocol is KN. The good news it's still based on nRF24L01 architecture (in practice more a BK2423).

yes what a short sight they are. They have just let go a golden chance to build up a standard “WL” protocol to lead the toy industry along with the then huge success of their 911

Well it seems like they want it to be a secret...

The RX board has 3 chips on it... one is the Inversense 6-axis gyro, one is completely potted in black like a $2 calculator (the one closest to antenna which I am guessing is RF chip), and on the other side is the main MCU which has had the markings precision ground off (looks sandblasted except for the 'dot' at pin 1).

It has ABE-JRWL252-6R written on it. The TX might shed some more light but I haven't taken it out of the packaging... hoping to return it for a refund so I'm waiting to hear what my seller is going to do. They seem to think everything is A-ok since I bought a V252 and that is what showed up, despite the listing baring no resemblance to what I received other than size and model number.

There are some rumors that some new models of Wltoys will return to FlySky protocol.
@marcoose, do you have a A7105 installed in order to test with FlySky ?

I don't, but I will see if I can borrow the 911 remote back and try it out. I was hoping to get away without another module as I'm pretty happy with the selection of models for NRF and built-in, but if anything the A7105 is probably the other one I would add

Or switch to the new super-universal module

I have the a 7105 and got same quad blue guy spinners whole 9 yards but had bumper to striped that stripped feet and tried to Bing with flysky protocol hubs an protocol both no go or not using a step properly

I opened the TX here is best pics I could take help me if you can

ABE-2.4GPA-3A is on the back of chip having trouble uploading the photos

ABE compagny .... smell it will be compatible with the Sky Walkr protocol.
The same compagny actually are making the RF part for the last JXD quads (389, 390, 391, 393). The Sky Wlkr protocol is also compatible with the Cheerson CX-10 and CX-11 (probably the CX-30 too).

For the Sky Walkr protocol, the flipping channel is not (yet) working. I can sniff SPI log for identifying it if HexFet is reading this message

VDD_PA circuit is also suspiciously close to nRF24L01.

Sure. The SkyWalkr option still has the YD717 flip control on channel 5. If that's not working, if you can get a trace of using the flip control it should be possible to add the function.

What model will you use to get the trace? Might not be the same data for different models.

Thanks

Well I will try to capture for new JXDs. I know there will be also a Sixth channel (turn on/off lights) and maybe a seven one (turn on/off camera).

For the CX-11, the RFchip is directly on the main board.... means pitch between pins is 0.1mm so for me almost inpossible to solder wires as probe.
Hope channels are common with all these models. It's amazing how "ABE" compagny recently provided for all these toy quad the RF part.
