Align T-Rex 250 Pro DFC Combo Helicopter Kit (No 3GX)

This is the Align T-REX 250 Pro DFC Combination Helicopter Set. This combo package includes an Align 250MX 3600kV brushless motor, a RCE-BL15X 15A brushless ESC, three DS415 Digital servos, one DS425 Digital servo, a set of 205D carbon primary blades, the 250DFC Main Rotor Head Upgrade Set and more!
As basic devices for the T-Rex 250 Pro DFC, the popular DFC head offers a low CG and low wind resistance for direct and accurate flying reaction, with excellent high speed performance. The frame structure makes use of material integration methods, allowing perfect assimilation in between plastic alloy with carbon fiber, preserving structural rigidness while simplifying upkeep. A unique integrated gyro/servo mount makes it possible for quick removal, simplifying upkeep while keeping a clean total aesthetic appearance. An effective shaft drive system efficiently reduces tail power output loss and the tail transmission is an integrated system with an upgraded rudder control system, with strong building and no slop, leading to a more accurate control feel.
Although the T-Rex 250 PRO DFC is little in size, it?s loaded with performance and can carrying out any challenging flight maneuvers. No longer do you have to find a large open space to fly; you can delight in flying in your yard or a large indoor space. 
Functions:
Incredibly low CG and short primary shaft design, significantly lowers flight resistance, efficiently enhances 3D performance and speed
New style linkage rod design, complete assembly increases linkage rod rigidness, allowing the pitch slider (fan) to be omitted, leading to a head assembly that is much streamlined and stiff
Designed specifically for DFC rotor head system, improving DFC linking rod's strength and decreasing linkage detachment throughout extreme flight maneuvers.
Material integration technology used in frames, improving rigidness and simplifies upkeep
New style quick removable gyroscope installing platform integrated with rudder servo mount, efficiently makes use of frame?s inner space for streamlined upkeep
New anti-rotation guide
Strengthened landing skids improved durability
High performance shaft tail drive system, efficiently increasing rudder performance and decrease power loss
Single tail belt system with the brand-new counter weighted tail blade grips make it much easier assembly and improving rudder performance
Uses double point attachment design for no play and higher accuracy control feel
Structured design canopy
