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 set includes an Align 250MX 3600kV brushless motor, a RCE-BL15X 15A brushless ESC, 3 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 provides a low CG and low wind resistance for direct and precise flying action, with outstanding high speed performance. The frame structure uses material combination strategies, permitting ideal assimilation between plastic alloy with carbon fiber, maintaining structural rigidity while streamlining upkeep. A unique integrated gyro/servo mount allows quick elimination, streamlining upkeep while keeping a clean general visual look. An effective shaft drive system efficiently minimizes tail power output loss and the tail transmission is an integrated unit with a revamped rudder control system, with solid building and construction and absolutely no slop, leading to a more precise control feel.
Although the T-Rex 250 PRO DFC is little in size, it?s loaded with performance and can performing any difficult flight maneuvers. Not do you have to discover a big open space to fly; you can enjoy flying in your backyard or a big indoor space. 
Functions:
Very low CG and brief primary shaft design, dramatically reduces flight resistance, efficiently improves 3D performance and speed
New design linkage rod design, complete assembly increases linkage rod rigidity, permitting the pitch slider (follower) to be left out, leading to a head assembly that is much simplified and rigid
Created particularly for DFC rotor head system, enhancing DFC linking rod's strength and decreasing linkage detachment during extreme flight maneuvers.
Material combination technology used in frames, enhancing rigidity and simplifies upkeep
New design quick removable gyroscope installing platform integrated with rudder servo mount, efficiently uses frame?s inner space for simplified upkeep
New anti-rotation guide
Strengthened landing skids boosted toughness
High performance shaft tail drive system, efficiently increasing rudder performance and reduce power loss
Single tail belt unit with the new counter weighted tail blade grips make it much easier assembly and enhancing rudder performance
Utilizes double point attachment design for absolutely no play and higher precision control feel
Structured design canopy
