Flies very nicely, may be hard to set up.14 April 2017There are better brushed flight controllers out there for a cheaper price, but it can be argued that this one is more reliable, seeing as it hasn't burst into flames yet. When I got mine, I had a similar board (clone, with a few differences) that was very easy to flash. I tried multiple computers but none of them could pick this board up in DFU mode. I tried Zadig, as well as a few other methods of getting it flashed but none worked. If you encounter the same issue, you can flash it using DfuSe in the same way you flash the KISS flight controller. Once everything was wired up, and I highly recommend wiring your non-Spektrum receiver to UART2, not UART1, it flies very well. I have not tried it on 2S, but 1S works nicely. It has onboard voltage monitoring, which is completely useless unless you're using telemetry or an OSD. I recommend this flight controller for brushed builds.
