Xtreme upgrade part. Thrust Bearing Kit for Main Shaft (Belt CPv2) The stock main shaft bearing (radial bearing) is taking the large shearing force (up and downward vertical force) during a flight and this force make the radial bearing damaged.With Thrust bearings kit, it takes the vertical thrust load away from the stock radial bearings. And thus making the main shaft rotating more smoothly and reduce the chance of bearing seizing (damage).
