Name that noise

[jamesban]

Heres my brushless muggy. I just put new HD cups and diff gears in the front and rear with 10k oil. Im running a MM 2200 and its running 13/45 with a plastic spur on 4c A123. It makes a clicking sound when I throttle it for a few seconds. It's meshed properly but since the center diff was locked when I got it and Im guessing with this gearing, the locked diff and the plastic spur that the clicking is coming from the spur and pinion but Im only guessing? Im hoping its not coming from the new diffs? Can anyone here tell by the sound in the video? Anyway I plan to get the 45T delrin slipperential next payday so if its the spur it should solve that by having some slip I hope? Thanks. You can hear it around 7 seconds, 12 seconds and 40 seconds in the video
