CL Racing F4S V1.4 Flight Controller built in PDB and OSD
CL Racing F4S Flight Controller V1.4 AIO with built in PDB and BetaFlight OSD . New Version
Introducing the latest development in F4 AIO flight controllers. CL Racing F4S designed by Cheng Lin.
IMPORTANT NOTE: This latest 2018 version (V1.4) is compatible with all ESC's, no matter how noisy they are.
Earlier versions of this board may cause death roll with certain escs this version is spot on.
This board is designed to fully embrace all the features of Betaflight. In fact, this design is ahead of Betaflight, in this case, because it is designed to be fully functional when Betaflight 3.2 will be released. Everything works, except the buzzer, which will work when betaflight 3.2 is ready. It's a programmable micro buzzer. See video below for more info and to get a look at it. You can also have a look at the full wiring diagram and specs below.
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.
