This is my second build and a lot more complex than my first. I was hoping I could get some advice.</p><p> </p><p>The power distribution board is the Advanced Power Distribution PDB 500 (<a href="https://powerdrives.net/pdb500">https://powerdrives.net/pdb500</a>)</p><p>The flight controller is an APM 2.6 (<a href="https://ardupilot.org/copter/docs/common-apm25-and-26-overview.html">https://ardupilot.org/copter/docs/common-apm25-and-26-overview.html</a>)</p><p>And the ESCs are Hobbywing XRotor 40A 2-6S OPTO (<a href="https://www.hobbywing.com/goods.php?id=398">https://www.hobbywing.com/goods.php?id=398</a>)</p><p> </p><p>In my previous build, I attached the ESCs directly to the flight controller, although they had a BEC. I was also donated a BEC. So my questions are:</p><p> </p><p>Do I need a BEC for every ESC?</p><p>What if I plug the ESCs into the FC without a BEC, will it fry the FC?</p><p>The PDB has connections for the ESBs can I attach them there without a BEC?</p><p>The connections on the PDB for the ESCs are semi-circular, if I were to attach the ESCs here how do I do that? Do I solder them directly</p><p>Any help is much appreciated, I understand these are probably basic questions, but this is a bit more complex than my last build Thank you</p></div>Ardupilot 2.8 BRD or Gerber fileshttps://diydrones.com/forum/topics/ardupilot-2-8-brd-or-gerber-files2020-02-24T17:53:15.000Z2020-02-24T17:53:15.000ZMINDS-i (Levi Wilson)https://diydrones.com/members/MINDSiLeviWilson<div><p>Does anyone know were the 2.8 board files are located?
