KISS FC Flight Controller

Product Rating:

Product Review (submitted on June 20, 2017):

I needed to upgrade my flight controllers from F1 processors since Betaflight is dropping support for these controllers. This KissFC clone seemed to be an economical way to do that. I ordered two and received them in 4 days (with standard shipping)! The controllers are pre-flashed with Betaflight but it is an older version. I tried for several days using various tools (DFUseDemo, DFU Flasher, BetaFlight) and drivers to upgrade to the latest version of BetaFlight with no success. Some tools reported a successful flash but when connected to BetaFlight the older version was still there. I finally downloaded the KissFC software from the Chrome store. The KissFC software would not connect to the board since it is a clone but it apparently downloaded and installed the correct drivers. The next time I connected the controller to BetaFlight in bootloader mode, it showed DFU where the com port is usually shown. I went to the flash utility, downloaded the latest version for the KissFC and it flashed sucessfully. BetaFlight now reports it is running the latest version of the software.

I'm very impressed with the controller. My quads seem locked in like never before. PID tuning was very easy also.
