Introducing the latest development in F4 AIO flight controllers. CL Racing F4S designed by Cheng Lin.  

There are rumors that the designer, Cheng Lin, spent months in complete isolation working on this design atop Tibetan mountains in California. When he returned, he had a long beard, dirty toe nails and nothing but rags for clothes. But he was also wearing a big smile. To this day, Cheng has not once discussed his moments in isolation. Seems imminent he is preparing for another hiatus. We certainly can expect to see great designs from him in the future as the hobby evolves, just like this one.
