The E7 is my first solo build, relatively straight forward and enjoyable up until the tail hub. The pivot ball in the bell crank was stripped on arrival, requiring epoxy repair. Upon disassembling the tail grips, I found that the radial bearings were oriented in opposite directions on each side of the grip, and they were exactly opposite orientations of those in the grip on the opposite side. Not only am I unable to determine which direction the radial bearings should be facing on either side ( the pictures are not detailed enough), I am unable to remove the bearings closest to the center of the shaft on either side without (I fear) damaging them. Please help!
