DIY QuadCopter with KK Board
Finally have the time to post this being doing this for quite sometime now, finally finished with a good result but still need to brush my flying skill a bit more 
Most people in Multimotor consider this as a mini QuadCopter but to me this Quad considered medium size Quad
This is what I call mini QuadCopter:
Size Different when side by side
the mini haven’t have it maiden flight yet as number of problem with the electronics setup, will need some new part to fix that but the medium quad is flyable!
Will post flight video if I have one in near future!
