why is there a stiff spot as motor cools down
I noticed that my 3635 950KV brushless motr when landing , spining the prop by hand its perfect, then after about a 3 minute cool down its stiff as though the bearings are tight, then after 5 more minutes totally cooled down the prop spins freely again . I never saw this before with a brushless motor ,yet it flys well doesn't get over hot ,does anyone know whats going on with this motor?
