I received an iPower 8017 from funtobuyonline and its shaft has a bit of a play. After careful inspection, it's clear that the bearing disks are not tight enough. In the beginning I thought that this wouldn't be noticeable once its powered on but after doing a test run today, the footage is practically sh*t since the motor is used for Yaw and the shake it produces is transfered to the whole gimbal. I'm trying to contact FtBO to have it returned, but thought I'd post here in case someone has had similar issues.
