If your align 550 is designed for 6s don't worry about the HD. A 6s esc will have a BEC built it. The Hobby wing 100amp Low voltage is an great example. Now the same esc for High voltage does not have the BEC and will need an RX pack.

Does the polarity of the servo wires matter I can’t find any info on this? Also direction of the mounting for the ikon2 is it micro USB port forward if I’m mounting on the top behind the awash?
