2.Before assembling the main gear, please use a cutter knife to cut off the part marked in yellow on the tail drive gear(approx. 0.5mm).
This is using the same separate type design of TREX600, easy to replace the gear by removing four screws, no need to remove the one-way bearing.
This new main gear is great for the balance. New super strength plastic-steel material, multinational patent design, light weight, and special cooling blade design is good for lowering the temperature of electronic equipment and motors. It can efficiently increase the wind flow.
Use for TREX450 XL/CF/SE/S(tail drive gear 25T)
