Hello Angel, we took long time to do video meeting with you and to guide you to find the real problem of the system. After we found out the problem together, we are able to make the new motor for you. Since we have upgraded our motor and system so by that time, we don't have that motor in stock. We need to make specially for you. We are sorry it took long time but finally we have solved this problem. We are upgrading our products all the time and hope we can still have some cooperation in the future.
