Has anyone installed bearings in the wheel hub? How about updates to the anti-rotation plate for the electric brake disk? I found that the screws are not quite long enough (only two or three threads) and that there is a space between the back to the anti-rotation plate and the wheel hub, which can cause the brake to drag if one of these three screws come loose. Maiden was completed this past weekend. It flew great!! I noticed these during the post flight gear inspection.
