These revving motors will work well for quadcopters on 130mm frames and 3" propellers.
EMAX company in the marking of motors indicates CW and CCW not the direction of threads, but the direction of rotation of propellers , ie CW motors with normal direction of rotation have reverse CCW threads, and motors with CCW direction of rotation have normal CW threads.

Attention! При установке слишком длинные болты могут повредить обмотку мотора, что выведет его из строя.
Хорошие крепкие и удачные моторы! Очень хорошо работают и тянут реально под 400г. Кому надо летать на мелкашках без телепортации, хватит с головой. На 1000 Диноджи 4 банках летает 7,5 минут в полном газе!!!
