I have read many posts suggesting low pinion( 12-14 ) with a 54 tooth spur. However in the manual and the site it suggests an 19 tooth pinion with the 54 tooth spur gear. I just purchased my first 3s lipo and was wondering how most of you actually gear your Slash 4x4's. For other needed info it is a Sky Lipo 3 cell, 11.8 volt 5000 mAH battery. I plan on bashing this coming weekend so I have a few days. Thanks in advance, for the advice. I look forward to more of the same courtesy and help I have always received here.
