Testing the KK2.1 with Steveis 1.8S1 firmware.
The stock FW that comes with the board (1.5) and the new one hobbyking released (1.6) are both useless for acro.
A huge thanks to Steve for all the effort he has and continues to put into the KK2 boards for us all to enjoy.
KK2.1 FW version 1.11S2 and 1.12S1 for Beginners is now available
