New 2mm 3K carbon fiber side frame for simple yet rigid frame construction, not only for easy assembly and maintenance, but also allowing capable of 730MX(850KV) motor to increase fight power.

Integrated swash anti-rotation guide and gyro mounting platform.


Equipped with new high strength cnc m1 helical main gear and tail drive bevel gear assembly, featuring reinforced overall gear structure and increased gear thickness, effectively improves gear's anti torsion ability to prevent gear from deforming under extreme power, reducing gear wear and power loss.

Power upgrade to 730MX(850KV) motor, the feel as If a turbo charger was added to the helicopter, capable of high efficiency, low current and low temperature, with dramatic 700 class flight performance in 550 class helicopter.


Utilizes newly developed, highest spec and superior anti-wear material to increase the overall strength and durability for torque tube drive gear. Effectively minimize gear striping and crash damage.

Rear mounted rudder servo mount & carbon fiber gyro mount.


Equipped T-REX 600 class tail boom set, supporting with 600mm main blade and increase tail stability.

Brand new tail blade designed to sustain optimal tail locking performance under high head speed and extreme flight conditions.

High quality new tail gearbox design, combined with new dual point mounted tail pitch control assembly to minimize slops and increase rudder control precision.
