CRM2413A Brushless Metal Motor Contra-Rotating 1300KV | CRM2413, Prop Adapter Included, Two Propellers Included, Works with Two ESC, Strong Power Supply

I bought 4 of these contrarotating motors and they are all fantastic. Excellent build quality and VERY powerful. The description lists their thrust values using a 3S battery, but they can readily handle a 4S lipo with the included 9 inch props as well as some other 8 and 9 inch propellers I had. The motors were only warm to the touch after flying. I also used larger 40 amp ESCs for each motor.

Good motors but you dont have much options for changing the prop, make sure your esc's are identical and to remove one of the signal wires if your using a y harness.

CRM2413 1300KV Was Ship to me with a SEIZED rear motor and a piece of the prop is missing. The thing is it was not damaged in shipping it was well protected .I Blame the Quality Control at the Factory.So it will probably take a month to get a replacement .
