64-BIT ANDROID OPERATING SYSTEM

The AX12 combines RadioMaster's proven radio control system with RadioMasterOS, an Android-based platform that simplifies setup, configuration, and field operation—without compromising reliable control. RadioMasterOS is RadioMaster's first Android-powered operating system, built specifically for radio control. It provides an intuitive model setup and adds touchscreen access to compatible Android apps for configuration, telemetry, and mission planning. This is not Android layered on top of a radio—it is a dedicated radio control system enhanced by an open Android foundation.

MALI-G72 MULTI-CORE GPU, 4 GB RAM + 64 GB STORAGE

An octa-core processor, 4 GB of RAM, and 64 GB of storage deliver smooth performance for control tasks, telemetry viewing, supported ground station apps, and utilities. The 5.5-inch HD IPS touchscreen (1280 × 720) delivers sharp visuals and 1000 nits brightness for excellent visibility even in direct sunlight. The responsive touchscreen interface makes navigating menus and adjusting settings quick and intuitive in the field. 

FULL-FEATURED RADIOMASTER TRANSMITTER

At its core, the AX12 remains a full- featured RadioMaster transmitter. It supports full 16-channel ExpressLRS control with advanced mixing, arbitrary channel mapping, custom curves (including 12-point custom curves), adjustable dual rates, and channel locking. Preset and user- defined model templates, full model import/export, custom model images, configurable voice prompts, and support for Tools Lua scripts provide deep flexibility for advanced setups.

ExpressLRS SUPPORT

The built- in ExpressLRS LR 1121 module supports 2. 2.4GHz or Sub-G 900MHz operation with low latency and strong link performance, and supports Wi-Fi OTA firmware updates for the internal RF module. MAVLink passthrough enables compatible apps, such as QGroundControl and Betaflight Configurator, to be used directly on the radio for supported workflows.

HDMI INPUT & OUTPUT

HDMI input supports video from compatible digital video systems on the AX 12 display, while HDMI output mirrors the screen to an external monitor or projector for teaching, review, or team use. Using the DJI Fly app and a simple USB-C OTG connection, the AX12 can display the live video feed from DJI goggles directly on its built-in HD screen. This enables passengers, spotters, or instructors to view the flight in real time while the pilot continues flying with goggles. The mirrored display can also serve as a handy backup screen for safety or for recording or live-streaming the flight feed.

Buy it! Lifesaver!
Size: 16oz
Yes, buy it when you don't have a spare tire because you will need it! I live in Florida and flat tires are just part of living here! Saved my life twice already and is absolutely self explaining! Cheaper then a spare tire, lighter than one too! Just throw it in your trunk and best case you will never need it but just in case!

Difficult to use and eventually hose end broke
Size: 24oz, Size: 24oz
I purchased this can of Fix-A-Flat to fix, what I believe, is a rim leak on my truck tire which needs to be filled once every week or so. When I attempted to use the product I let some air out of the tire (down to 25 psi) so it would be easier to dispense the contents. The instructions on the can say to have the valve on the tire at the 6 o'clock...which I did as well. When I attempted to make the connection using the swivel connector on the can's hose it was difficult. The hose on the can is very short and stiff and because it came coiled in the can's lid, did not want to straighten out making connecting it to the tire a very awkward process. It was hard to screw the hose end on the valve without it binding so it felt like it was cross-threading. I have machined aluminum valve caps and they go one very easily so I know the threads on the tire's valve stem are clean. I finally did get it on and when I attempted to dispense the contents it filled the hose but that was about it. I could not see any contents flowing thru the hose at all. I assumed it was not on far enough so I took it off to try again and the contents sprayed everywhere showing it was indeed under pressure....just not going into the tire. After multiple tries the hose end eventually just broke off and stayed on the tire's valve stem. I was able to get it off, but at this point the can is useless to me. Obviously I cannot and will not recommend this product. I have used this product before and had success, but that was when the hose was longer and wired to the side of the can making it much easier to use, versus how they are shipped now. I would recommend going with another product or possible going to a box store (which is what I plan to do) to find one that does not have this design. At the very least, if you do choose to disregard this review, I would try it with the tire's valve stem at the 3 or 9 o'clock position which might make it easier to thread the hose end on to the valve stem,. Also, if you choose to go this route you might just be throwing your money away. I attempted to get a refund from Amazon and was directed to the manufacture's web site. From there you are directed to use the 800 number of leave a general message that is in no way connected to your Amazon purchase. Past experience tells me it will not be an easy process so it looks like I am out the $12.

This is a necessity for anyone that tries a car!!
Size: 20oz 6pk
I haven’t used this yet, but I bought a case to give to my family members. My friend who came outside to a flat tire. It was a Sunday in Utah so there was really no one that could fix it. Walmart told her to get this product. She had to drive home immediately following using this product (300 miles) It has been over two months now and my niece is still driving on that tire. It was a brand new tire that was costly so she decided to just wait and see how long this product will work. Great gift for anyone in the family that drives. This does not work on a blown tire. If you wake up in the morning and your tire is flat, or you get out of class and your tire is flat, just use this product and no calls need to be made.

👌 Kaboom! 🌹 Air fills the room! 💥 Inside your tyres, that is ✨💖
Color: Orange, Number of Items: 1
Right out of the box this little wonder inflated my motorcycle tires to the decimal. I set it to .5 over on the digital pressure gauge so the pulling out doesn’t lower the PSI. This machine worked easily, flawlessly, and if you’re on the fence, I’d say pull the trigger. The hoses on mine screwed together making it just about the right length. Dunno how long it lasts but - wow - not much bigger than an old transistor radio & was controlled intuitively. Easy port on bicycle, cycle, auto. It’s a wow & I’m hard to please.
