Ok, so it turns out 2 of 4 motors are bad or going bad on my drone. So instead of waiting for it to drop out of the sky I've decided to go ahead and replace all 4. I've been looking at the oem dji motors or the tiger mn2214 motors. I don't care about longer flight times or performance but I would love to get a smoother motor if it truly does help. Does anyone here have any long term experience with the motors? I would buy a set from KDE but their out of my budget. Thanks in advance.
