Hi mate OK we can start from the start , did you set up transmitter as aero No mixing of any type the KK does all the work , are all the servo leads the right way round on the board , the lighter colour wire is signal wire , test by going into monitor screen if all is ok in monitor screen have you got the motors plugged in to the right pins m1 = motor 1 ( all test should not have props fitted ) if you arm quad and give a little throttle till motors spin if you hold quad up off floor and give forward input the rear motors will speed up try and come back to me
