This is the Align T-Rex 300X Electric Helicopter Combo Kit, with motor, ESC, and Servos. The T-Rex 300X is small in size but by no means small in performance. This model adopts DFC rotor head unit, low CG and low wind resistance providing direct flight responses. The carbon fiber main frame is made of composite material and with reinforcement plate and brace assembly effectively enhancing structural intensity and torsion resistance. The narrow body design makes the mechanical structure much stronger. The battery slider and top-mounted motor design is anodized a bright red color to bring out eye catching texture on this model. A thickened aluminum alloy tail boom is included for the best torsion resistance and increases the tail support rod lifetime. The progressive lightweight landing skid makes this model the leader in its class. Plus the fiberglass painted canopy features lightweight and low in wind resistance.

The standard high torque and high efficiency 300MX 3700KV/2216 brushless motor not only contributes to dramatic power increase, the high efficiency cooling system enables cooler operating temperature during and after flights when compared to motor of previous generation. This provides consistent power output and keeps stable RPM in non-stop 3D flying for presenting perfect performance. It pairs with digital HV DS450 and DS455 servos, supporting 8.4V output, fast response and high torque. The new 25A brushless speed governor support 5~8.4V adjustable BEC voltage.
