RE: esc location
Druss, 10cm!? Really? Isn't that the length of the entire stock HBK2 battery cage? 10cm from the front end of the receiver is well past the front of the cage. I don't see how this could be possible to accomplish on the King.
I servo taped my 30A Dynam ESC to the side of the battery cage. In any case, general advice is to keep the ESC as far away as possible from the receiver.
