EMAX would like to introduce a new line of RS1306 motor. Redesigned from the ground up to have better performance and smoother flight. Utilizing the T-mount system you can now have a small lighter motor. Also included is a bottomless design to continue to lighten the motor, decreasing crucial weight in the corners to help your quadcopter to turn more sharp and consistent.
I used many of these motors. They work really well for me in a very demanding application. So far I had no failures. Great motor, good price, I recommend.
