Hello,
i didn’t found the search function for the forum. so i ask the question and hope it doesn’t allready exist:
i am using davids PCB with build in BEC and 3 ESC’s without BEC.
How do i wire up the KK Board, because i have to power the board at M1 but i have to feed power to M2-M8 because the servo also needs power.Do i have to use a second BEC?
Thanks for your help.

18 October, 2015 at 19:33 #21532SzilardParticipantHello, I am a newby copterwise, i have a kk2 and some turnigy multistar 20A blheli ESCs, i wire up like in the video shown by David, but when i try to run the copter no respons comming from the motors or servo. The reciever test is ok, but nothing happening. Can you help me? Regards Szilard
19 October, 2015 at 02:13 #21541ChadwickParticipant@Szilard have you armed the board? With the kk boards you do this by holding throttle off rudder to the right.
21 October, 2015 at 20:35 #21673SzilardParticipant@Chadwick many thanks, it worked, but now i have other things to clearify. I have connected the servo to chanel 7 out but no movement on it. I move the rudder stick but nothing, no reaction? Also is it normal if i push the yaw to one side the opposite motor stops totally, should it be like thet or is a cheap bad quality ESC is the problem. Turnegy Multistart 20A blheli? And also if i hit the thottle to about 30% 1-2 motor starts up but not all at once? Of course the throtthle curve can be also some problem, but i set up as David showed, someone can help. Any idea apreciated??
Regards Szilard
14 November, 2015 at 21:35 #22555SzilardParticipantHello,
I connect the servo to the output 7 (as in video) but does not moves at all. I tried output 4 but nothing. Reciever test works OK with the rudder, can be that there is not enough power from the KK2 board, should i use external power supply for it?
Any idea?14 November, 2015 at 22:22 #22562SzilardParticipantOK, I figured out myself 🙂
