    The noise...

    Well i built an e-revo frm the ground up, first thing i noticed is the 2200kv motor doesn't flow ( as it stops ) i have owned a 6800kV for the 1/18th and it just rolled without any friction, and no noise, the 2200kv makes a TON of noise, is this normal? it sounds like the gear mesh is way too tight or something always... awful noise.

    Also i have:

    23T pinion, and a 65T spurr which don't fit together, too tight, should I get a new what err,, 60T spurr or so?
    I heard the 21/54 is a great combo

    all my MMM motors make a bunch of noise. especially during braking. i found it odd the first time too but they are all noisy. so i roll with it. double check your mesh and let it roll.

    mine does the same noise, i think the magnet on this motor are just really strong that it makes all that noise.

    From my experience, the low KV motors make all sorts of noise and dont roll smoothly. I believe this isdue to the much stronger magnets in them. 4 pole motors are even more.

    The spur gear/pinion gear combo is larger toothed than the 1/18 you're used to hearing. The 32p will be louder.
