The design of the Aluminum Main Blade Grip with Thrust Bearing was to optimize for rigidity, stability, durability and overall performance of the BLADE 450X / 330X / 330S helicopter. It is directly replaced the stock plastic.
The new upgrade product is designed with Thrust Bearing in the inner side of the Aluminum Main Blade Grip, to increase Spindle Shaft and Radial Bearings support and significantly reduce play. Radial Bearing system is technically re-engineered more reasonably with the Thrust Bearing between two Radial Bearings, instead of placing the Thrust Bearing outside like the stock plastic Main Grip. No more pressure from the Spindle Shaft Screw lock, or come apart, or lost easily during installation when the Thrust Bearing is placed in the inner side.
