Hello again forum. I just finished working on my Kraton 4s and have a question. After getting the slipper all assembled, re-tightened with more thread lock I noticed it is very loud when rolling it. A lot louder than the Outcast 4s I have that is basically the exact same thing expect for the spur gear. The Outcast 4s is fully stock with stock Arrma spur and Arrma 15T pinion, and my Kraton 4s has the Hot Racing spur with the same 15T pinion. It reminds me of how loud all the 6s's were that I had. I redid the mesh several times and have it perfect, but its still very loud. Ive attached a zip file to extract of a recording to show you what I mean. The first sound is me rolling the Outcast 4s back and forth, then the 2nd is the Kraton 4s. Normal? Any ideas as to what to check? The diffs are perfect and turn nice and smooth so Im pretty sure its pinion and spur related. Thanks
