Missing bearings

[TimS]

Bearing part number

You should have got 30 bearings in 3 tubes. The on the top of the arm that has the motor mounted to it. The hole that the motor shaft goes through doesn’t get a bearing, only the bottom hole for the motor. All others will get a bearing on the top and bottom. I made this mistake but caught after assembling one arm.

See above link for what I found after watching the 4.1 arm upgrade kit video. Luckily I only had 1 arm together. Video is at the link below.
