These boards are PRE-FLASHED by Altitude Hobbies with the latest OpenAeroVTOL firmware V1.6 in collaboration with HappySundays and Ran D. St. Clair.
Many people have asked for a pre-flashed board as it is sometimes difficult to get your PC configured with the proper drivers, application software, and of course you need the programming cable to flash them yourself. You will still need to enter the parameters for your specific aircraft, but that is easily accomplished with the buttons and the LCD display.
This powerful firmware is useful for much more than just VTOL aircraft. It is a general purpose flight controller that can be used in all sorts of aircraft and for all sorts of purposes. People have even used it in cars to control oversteer. It can turn most any aircraft into an easy to fly trainer and is also a lot of fun in 3D aircraft that can be made to auto hover. It isn't recommended for simple multicopters as there are better and simpler dedicated flight controllers for that purpose, but it can fly multicopters as they are often a part of VTOL aircraft. It has a general purpose and very flexible user interface that is not aircraft dependent. The user manual and supporting documentation are very complete and combine with the board to create an excellent educational lab for understanding the basics of flight stabilization.
Ongoing and free product support is offered via this RC Groups thread:

If you want to use the Excel based GUI (Graphical User Interface) you will still need to set up your PC to flash the board yourself. Fortunately, the GUI is just a convenience and is not necessary. The on board buttons and LCD display are all you need. The GUI is available here:
Thank You to HappySundays for making all this possible.
