EMAX RS2306 2400kV Brushless Motor (CW Thread) (Black)
I personally think these rs2306 2400kv motors are the best emax motors to date. The amp draw is very minimal but still kills a 1500mah in 3 min. The motor and bearings are very solid just like the rest of the emax motors however im not a fan of the hollow shaft I have already broke a shaft in half on my second day flying and it was only from clipping a branch and falling to the grass. I also am not a fan of only clockwise thread they should bring the reverse thread back. As I clipped the branch with the clockwise thread and a clockwise motor direction the prop nut emediatedly flew off and the prop managed to stay on but when it landed the shaft snapped. I have crashed many times and way faster with the old rs2205 motors and have never had a problem. As a review I would say these rs2306 motors are deffinetaly better performing motors but less reliable compared to the old rs2205.
