One of the most classic ALIGN models, T-REX 600N nitro helicopter. In 2018, we bring you the brand new design of T-REX 600XN, it inherits the design of T-REX 700XN featuring innovation, rigidity and lightness. Extremely perfection and precision, the T-REX 600XN is about to excite your inner soul to bring back your passion for nitro.T-REX 600XN adopts the new direct to swashplate servo design, compared to the previous generation T-REX 600N’s push-pull mode control, provides precise and fast control! Utilizing the 550 Flybarless Rotor Head System features an extremely low Center of Gravity (CG) design, to effectively reduces resistance during 3D maneuvers, and increase flight responsiveness and precision. This designed maintains a 90-degree symmetrical angle between the Rotor Grip Arms and Linkage Rods for superior stable flight performance. The Engineered Narrow Body Design efficiently decrease gear abrasion and frame deformation during flight. The T-REX 600XN maintains the proper CG, by moving the engine forward to allow the fuel tank to be positioned in the center of the main shaft. CG remains consistent as the fuel level changes during flight.The new steel alloy clutch liner is durable with temperature control designed to avoid the exploding clutch liner or a breaking clutch housing. The steel alloy clutch liner extends the life to over a 1000 flights. The Receiver Mount provides cable and wiring protection, and easy to maintenance by removing a few screws from the mainframe.The new high voltage output: 6A 7.4V BEC with down / regulation system for constant power to the CCPM server channel for receivers and servos. Includes a built-in one-button push glow plug igniter eliminating the hassle of using traditional electric clip plug on igniters. Also increased external high-frequency filter capacitance to effectively reduce the interference generated by external noise; such as high-speed and high torque servos. The brand new DS820M/DS825M high voltage brushless servos use brushless motors for fast speed, high torque, superior, and efficient reaction time allows the Align 600XN precise, fast performance. The new CNC machined aluminum case design is aesthetically appealing while acting as a highly efficient heat sink.The new generation of T-REX 600XN innovative design will excite your inner soul to bring back your passion for nitro!
