The carbon fiber main frame is made of composite material and with reinforcement plate and brace assembly effectively enhancing structural intensity and torsion resistance. Narrow body design makes mechanical structure much stronger. The battery slider and top-mounted motor design with anodized bright red color brings pretty texture on this model. Thicken aluminum alloy tail boom for the best torsion resistance and increase the tail support rod lifetime. The progressive lightweight landing skid making this model the leader in this 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. Allow to provide consistent power output and keep stable RPM in non-stop 3D flying presenting perfect performance. Also 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.

T-REX 300X is tiny but everything all-in-one so that can perform well in not only in-door show but also outdoor 3D flights. This model offers you the best bargain price allow you to have fun flying at any time.
