Ruby Store
We don't have our own online store, but below are some of the manufacturers that sell air units, ground stations, VRX-es that are ready to use with Ruby (just buy, plug and play) or that can be flashed with Ruby and used in Ruby.
If you really must (support open source projects): 
OpenIPC Ruby air units
RunCam air units
EMAX air/ground units
Example: Cute litte air unit, about 50 mW radio power output, perfect for very small drones.
You can buy it here
