The latest version of the CLF4S is here!

Version 1.6 will have voltage scale change from 110 to 160 in the battery tab, and user selectable BEC is now 7.2V or 5V.

V1.5 added some small changes to improve how the board handled larger motors. The F4S version, this CLF4 FC is packed full of the latest features and technology in the industry, like camera control. Loved because of its dependability and affordability, the CL Racing F4S is a fan favorite!

Build Tips

• 1. Solder the main battery lead to the board first.
• 2.check on the bottom label :UART 1- >sBus. UART 3 -> telemetry
• 3. use TX4 for the smart audio if you use it.
• 4.if you solder on the buzzer, go to CLI paste " set beeper_frequency = 0" enter and "save"
• 5. For use telemetry. select the uart3 as smart port. and go to CLI do " set tlm_halfduplex = off " you have to use this command to make it work.
• 6. for use 4 IN 1 esc. you can use the cable comes with the FC. but you may have to shift the pin around to get the correct motor layout. if you esc has the current sensor, you can use the solder pads label as (EXT) for the external Current sensor ( INT ) for internal current sensor
• 7.after soldering everything on the board. check continuity on all 4 motor signal wire to battery positive and battery negative. very important. if those have continuity. you will have a big problem. smoke stopper won't stop this.
