This is an optional Align Main Gear Set, and is intended for use with the Align T-Rex 450 XL, CF, SE and S (tail drive gear 25T). This main gear set uses the same design as the TREX600, for easier main gear replacement, eliminating the need to remove the one-way bearing and provides improved balance. The super strength plastic-steel material is light weight at 26.5 grams a set, while the special cooling blade design helps to increase airflow, lowering the temperature of electronic equipment and motors.

NOTE: Modification to the frame and tail drive gear may be required for proper fit.

Includes:

• (1) New main drive gear (150T)
• (1) New autorotation tail drive gear (106T)
