T-REX 150 Main Blades by Align.

This is a replacement Align 120 Main Blade Set. This package includes two complete sets of Black/White main blades. These blades are manufactured from PA-747 industrial grade ABS, that feature a metal ring around the blade grip bolt for added safety and stability during high stress maneuvers. The "150 Main Blades" are specifically designed for the T-Rex 150X, in order to withstand higher headspeeds, & significantly reduce the risk of failures due to higher loads placed on the blades at these higher headspeeds.
