I've spent the last several hours trying to figure out where to purchase a none Chinese knockoff of the Arducopter flight controller.
I've seen references to 3dr but I can't find an Arducopter flight controller on their site and Google searches just lead me to lots of what appear to be knockoffs.
Can someone please point me to a reliable source for an Arducopter flight controller.
I live in the U.S. and would like to purchase from a U.S. seller.
Thanks in advance
