    Auxiliary Flight Function

    Built-in highly precise barometer to detect the height, the version with Cetus FC benefits from great stability due to its position hold mode, and auto-hovering, which enables the drone to stay at the current height. This function also ensures an emergency landing of the drone whenever loses control or is on low battery. Meanwhile, its stable flight allows you to catch the best footage with the FPV Goggles. It really does an immense amount of fun and ease of flight for all pilots. Recommend flying it with BETAFPV VR03 Goggles.

    Powered by 2S, Cetus X has loads of punch and speed, making it smoother and more suitable for outdoor practice, great for the next level. For indoor practice, the Cetus Pro with 1S power, which has the same auxiliary flight function, is easier for initial pilots to control and fly.

    Note: The position hold function is only available in N mode.

Combining this VTX and the excellent radio link ExpressLRS 2.4G, pilots can fly whoop drones longer to explore more possibilities and fun. In addition, C04 FPV camera (based on Caddx Nano Ant Camera/Runcam Nano 4) shows a better quality in FPV flight compared with C02 FPV camera

        Superior Customer Service; 100% prefect and functional, BUT...
        Number of Items: 2
        This product fits perfectly, after all it's just a simple piece replacement. The big deal is the counter reset, and this is where Customer Service outstands. People complaints about the difficulty of following the reset instructions, and with reason, as they are lengthy. But that is the printer you have, that is Epson's product. You either send the printer to them and pay the premium fee, or do it yourself, but you have to play their game. This is not Seller's fault; on the contrary, Seller put all their effort to include each and every steps you need to fix the problem, no matter what printer model you have. They included most, If not all, printer models you may have. They provided super detailed instructions to ensure your success; keys where needed, no keys where not needed, printer drivers location to download and ensure the resetter will work and, best of all, support if you need it. You have to contact them through Amazon asking for the user's manual (instructions; yes, the lengthy ones), the reset program and the reset keys if applicable (this depends on you printer model; some need the reset keys, some do not). And this is where you get concerned: When are they going to answer, now that my printer is locked? You think (I did): it is weekend, they will probably answer Monday or maybe Tuesday (after all, that already have the money, why care?). Well, I was absolutely wrong, they answered during the weekend with all necessary to have the printer back, up and running; Thank You. Some tips: 1. There is nothing wrong with the software (if got from a reputable source, and they for sure are), so get it without concerns. 2. Get the printer driver as advised; it is quite probable that the software will not work if you don't install the correct driver; don't forget to restart the computer after the driver installation. 3. Make sure your printer is set up with the USB connection Enabled (mine was disabled and that caused a headache: ET-4800). 4. When the resetter instructions call for Initialize the Counters, don't do it, not yet; select Check instead, just above Initialize. If you cannot read (Check) the counters, you will not be able to Initialize them: fix the connection problem first (make sure you installed the printer driver and RESTART the computer, make sure you enabled the USB connection in the printer, and make sure the usb cable is correctly connected). It's not Seller's fault to make long and complicated instructions, that is actually their effort to make sure you have all you need to succeed. Buy with confidence, this works: if you cannot make it work, you may find someone you trust to help you out (your kids or grandkids know a lot for sure), or just let Seller know, they are willing to help you out. Best regards.

        Works great for ET-2720 - no key needed for this model either.
        Number of Items: 2
        This worked great for my ET2720, and the price is exceptional compared to what you could pay to have Epson complete this process. I’ll admit that it took me a while to complete it, maybe 25 minutes, but that is because I was being cautious. When I do it again, it would likely take 5-10 minutes having already done it once. I did read a helpful review and followed some of their advice, and that might have added some extra time. Not sure if it is important to download the driver that the .zip file directs you to, but it is from Jan 2025 and is outdated so you might be regressing to an older driver version in order to complete this process. I’ll add some things to note: The driver software in the .zip - it is just a list of URLs to an Epson driver download for different printer models in an Excel document. Make sure you have a way to open a .xlsx file. You don’t need a reset key for all printer models. I didn’t need one for my ET-2720. Each download from their website has different instructions in the .zip - so they should tell you if you will need one or not and you can contact them ahead of time to get it. That’s another thing. Don’t waste your time with the instructions in the box. Just use them for the simple ink pad replacement steps and how to download the .zip from their site. Then just follow the .pdf that is included in the .zip from there on out. Solid choice for this solution!

        Awesome directions on install process. Printer USB cable is NEEDED to complete counter reset.
        Number of Items: 2
        These Gubffon waste ink pad replacement tanks are amazing. The company has gone above and beyond with the written directions, right down to the counter reset online instructions, they are easy to follow, plain text with clearly defined photographic images. Tank install literally took about five minutes, counter reset took a bit longer, but as my computer decided to do updates, typical, so I am unsure of the exact timing. Once installation was completed, I needed to do printer maintenance, but mainly due to my printer having not been used in quite a while. My Epsom 2720 is running like new. Would highly recommend this product. ***A USB printer cable is needed for counter reset***
