Whats obvious looking into the motor stators and looking at the overall finish is that its well made. Or at the very least, much better than I expected for the price point(cheap from china, less cheap from amazon). The anodizing is nice, the windings look tight, wiring is solid enough, blah blah blah. Manufacturer specs are below the pictures, but the proof is in the pudding.
After doing some calibrating and adjustment on my Racerstar 30a lite ESCs in BLHeliSuite, the motors started running really really smoothly. The Racerstar 30a lite ESCs are also really great, but I did have a hell of a time diagnosing an issue with two out of my six ESCc.
Turns out the different factory lines or warehouses let two slip out without firmware, or with corrupted firmware…? I have a whole crazy gripe about it in the multirotors section.
