Flashfire has been around for quite a few years. I believe they're a Chinese company making low priced joysticks and game pads, with their market usually being outside of the US, which is why it can be difficult to find their products available in the US. One of the main complaints about Flashfire products is the quality of the build and lack of any real software support as they generally rely solely on the default Window game controller drivers that come with any Windows OS, which means the drivers are only updated when Microsoft decides to update the generic game controller drivers for Windows.
Hardware quality also has a less then stellar reputation, usually the build is used with cheap plastics that tend to break easily and the electronics sometimes aren't put together very well. It's an inexpensive joystick, so you typically get what you pay for with these types of low quality products.
I'd also be very interested in your thoughts on the Flashfire HOTAS after you've been able to test it out. It does look like Flashfire has at least tried to make a "modern" stick with what appears (at least visually) to be a decent build. At first glance, it is obvious Flashfire took most of its inspiration from Saitek's first gen HOTAS controllers. I wonder if with this HOTAS controller that Flashfire has developed software for the controllers and also won't rely on the default Windows drivers. However, for the price, having a 32-bit HOTAS controller system is a good deal, provided the quality is there to back it up and that has been the main failing of Flashfire products.
