Hi everyone,
I was excited for my first flight after getting everything together but the KK board started with a sound and back light only , without any writing (KK board is new i have tested it once few months back and it worked). I tried changing batteries thinking might be voltage but it was the same.
if there is anything i can do to fix it on the spot please let me know
