When you upgrade to a  Main Brushless motor (plus a Main ESC) you are usually required to upgrade you tail motor as well to keep the rotation in check.  Instead of upgrading the weak brush tail motor to a stronger brush tail motor you should consider upgrading to a brushless tail motor (plus a Tail ESC) as well.  This double brushless upgrade is highly recommended to save you extra work down the road.       Requires ESC (Electronic Speed controller) to function.   Shaft size same as Feigao and Losi: 1.5mm (actual 1.33mm) Gear pitch: same as 4G3, CB100, V100D01/03, 4#6/S, 4#3b and Novus CP & FP Pinion: 12 teeth Speed: 11,000kv (actual appx 15,000kv) Weight: 10.9g
