The NEW T-REX 550X is definitely a significant leap forward in performance, enhanced by increased power, the integration of numerous innovative design changes, and lightweight improvements. The T-REX 550X performance is outstanding!

The brand new FL Flybarless Rotor Head System utilizes an extremely low CG design, reducing resistance during 3D maneuvers while increasing flight responsiveness and precision. A progressive design adds a gloss silver and red anodizing appearance which continue our quality development based on our 700 class helicopter. The T-REX 550X main frame utilizes composite material integration technology on carbon side frame plates, including the addition of battery mounting side rails, and a top motor mount design. In addition, the T-REX 550X's lightweight design is 200~250g (Combo250g/Super Combo 200g) lighter than our pervious model, this effectively increase the power and improves flight time.

The T-REX 550X utilizes the powerful 730MX (960KV) motor and our RCE-BL100A Brushless ESC which both are highly efficient providing superior power, improving the performance of the 6S power system. The NEW DS820M/DS825M high voltage brushless servos are extremely efficient and out perform other servos in this class. To protect these servos the new high-end CNC aluminum case function as a heat sink allowing the servos to operate at a lower temperature.

With improved performance and increased power, as well as included top of the line electronic equipment. The new T-REX 550 X will arouse your enthusiasm and devotion to the T-REX Family.
