mjx rc car protocol？

[nzjott]

hi just got my radiomaster tx12 here and want to use it on mjx 14302 hyper go rc cars, but I can't find a right protocol for it. I attached original rc for it.

The main IC does not have a proper marking so I don't know which RF component is being used. I need access to the TX and RX to reverse the protocol, if you are willing to ship the hw to France PM me.

It's really a pain to ship thing out from nz, is there anyway I can dump the data and post ? I also have a radiolink r4eh rx and rc4g tx and want to see if there is anyway to dump things out of them

For the mjx, you can always try to do a XN297Dump in auto mode.

For the radiolink receiver have you tested the existing protocol : https://github.com/pascallanger/DIY-Multiprotocol-TX-Module/blob/master/Protocols_Details.md#radiolink---74

I tried but seems not work. As the old radiolink rc4g tx and r4eh-h / r4eh-g aren't compatible with the newer rc6gs radios. They even have free receiver exchange from r4eh to r6fg when the rc6gs first came out. ..

Hello, I am interested in the protocol for MJX cars as well. Are there any news? Thanks!

[pascallanger]

Unless I have access to a TX + RX nothing will happen.

I´ve checked the transfer costs. Approx 40€ in total for both ways. If anyone else would participate in a cost share I could send you the equipment. Lets see if more are interested in this. :-)

Is there otherwise a possiblity to dump the protocol with a pc and a modified wifi card?

I am also interested - I have a TX and RX .. not sure how much it would cost to ship from the US.. How does one go about reverse engineering it? This seems to be an autobind protocol and it's not compatible with any of the mjxq entries already in EdgeTX. The receiver I have is only marked with R30 .. my car is a hypergo H16BM brushless. I put an R85C that came with my MT12 in it but I think it would be cool to get the protocol working natively.

Why not just swap out the receiver for a DumboRC one and get a DumboRC remote? That was one of the first things I did for my MJX cars. The receivers are very cheap, and the transmitters don't cost much, either (and are way better than the ones that come with the MJX cars).
