Notorious Normal Notorious mesh sound? New out of the box tips?

[Grim_Skunk]

Hi all, just received my 1st Arrma. I read that the Arrma's meshing is loud. Just want to double check if this sound is normal. Feels like theres a slight resistance when rolling. Took it for a short test run, but still not sure. Also what tips do you have for me before I start bashing?

It's normal. It's metal on metal gears. I'd check your diffs to make sure they are full. Seems like they have had a lot of leaking diff issues as of late.
