Features: ●Incorporating the new generation 3GX flybarless system, with enhanced pirouetting compensating routine, and optimized stability for smaller helicopter. Together these features enable smaller helicopters to have control feel that resembles its flybar counterpart. ●Newly improved low wind resistance specialized flybarless rotor head assembly, with reduced distance between rotor head and frame, effectively lowering the CG for better 3D performance. ●Improved side frame design, with dedicated 3GX mounting location. 3GX can be placed in between frames, or behind anti-rotation guide, resulting in clean wire management and improved aesthetics. ●Unibody main shaft and servo mount, with modified side frame connecting points, simplifying servo replacement and improving ease of maintenance. ●Brand new MX series high efficiency brushless motor, with heat sink style casing and built in cooling fan, effectively increase heat dissipation during operation, improving power output. ●Longer battery mounting plate with integrated ESC mount. Not only is the battery mount more rigid, the battery can be shifted based on its dimension for better CG. In addition, the screw count has been reduced to minimize assembly and maintenance time. ●High efficiency tail shaft drive design, dramatically reduce power loss associated with belt driven system, and at the same time increase power output. ●Vertical rudder servo mount design moving the CG closer to center, improving agility during 3D maneuvers. ●Unique opposing weighted tail blade grips effectively increase rudder and gyro performance, for superior tail locking and higher precision. ●New aerodynamic canopy with paint scheme resembling the T-Rex 600E Pro, perfectly matched to the helicopter frame to create aesthetic perfection. Users must have a certain concept of security to operate the R/C helicopters. Be sure to read and comply with related safety notes of instruction manual before flying.
