Special note for Castle Creation ESC’s created specifically for multicopters
Castle Creations have created a pack of four ESCs. You get three ESCs without a BEC and one with a
BEC so you don’t need to remove the 5V wire from the ESCs connected to M2 to M8.
The ESC with a BEC will be connected to M1 so that it powers the KK2.1.X and receiver. The problem
is that the other ESCs need a 5V signal “up the servo connector” in order for them to work. If they
are plugged into M2 to M8, they don’t get 5V and therefore, won’t work! Strictly, you should use a
UBEC on a spare M2 to M8 output to power the other ESCs. However, providing you don’t have any
servos, you may want to consider bridging the M1 and M2 to M8 5V power busses.
