Meshing the Neu motor pinions

[Savage03]

I can say a little on this, I started with a plastic spur on my savage and a novak hardened pinion with the 2200 motor and rolling it by hand or as its starting to take off it is indeed very loud, loud enough I swore I did something wrong. After it was going tho it would get alot more quiet but still a bit noisy so I ordered the HPI metal spur and robinson pinion, just tried that combo last night and it was a bit more quiet then the other combo, lot better in my opinion but at slow speeds you will hear some noise no matter what.
