This is the VOX 14x5 Electric Wooden Propeller by Precision Aerobatics. This prop is a must-have with the Addiction X (PABADX-RB, PABADX-BCF). This is the highest range propeller for the Thrust 45 Revo with the Gen 2 4S 14.8v 2600 mAh pack and is an excellent overall propeller for extreme 3D specifically tuned for good punch out of a hover and slow 3D.
