One of the motor has stopped functioning (Technically it works but it cannot overcome any resistance and it turns really slowly) I can say with confidence that it is the motor itself and not any wiring or low battery problems. It still has a good angle reading and all but it only turns at 12-13 rpms and I cant adjust the speed (In Device Info) So my question is Can I get the motor replace or fixed? or Is there any possible solution to this?
PS. When I first got the kit (about a week ago) all of the motors were covered in some oily substance. Is that normal?
