After my FC40 did a fly-away I thought I would try a different route. After a couple of failed EBAY deals I figured I would salvage what I could and try a DIY. Now being a newbie I am probably over my head. I have 4 motors, only markings on them is (readytoflyquads). Tried their website and not much info. I have the DJI 18A opto ESC's. Three ports labeled U,V,W, ??? The motor has three black wires? Any ideas on are the compatible and if so how to hook them up. The motors do bolt up to the 450 frame that I am using.
