Started with a 15 tooth on mine and temped 170 after 5 minutes. Dropping to 14 tooth helped a little. Dropping throttle punch quite a bit and then dropping forward power helped more but really made it drive sluggish. STEEL 12 had similar issues and remedied them in a similar fashion and also felt sluggish. I definitely would rather buy what seems like a bit much motor that I can tame with esc and radio settings. I've always had a pretty controlled throttle finger so a lot of motor doesn't make me nervous.
