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 main blades, the 250DFC Main Rotor Head Upgrade Set and more!
As standard devices for the T-Rex 250 Pro DFC, the popular DFC head provides a low CG and low wind resistance for direct and accurate flying reaction, with outstanding high speed performance. The frame structure uses material combination strategies, enabling best assimilation between plastic alloy with carbon fiber, maintaining structural rigidity while simplifying maintenance. A unique integrated gyro/servo install allows quick elimination, simplifying maintenance while keeping a clean total visual appearance. An effective shaft drive system efficiently lessens tail power output loss and the tail transmission is an integrated system with a redesigned rudder control system, with strong building and construction and absolutely no slop, leading to a more accurate control feel.
Although the T-Rex 250 PRO DFC is little in size, it?s packed with performance and is capable of carrying out any hard flight maneuvers. No longer do you have to discover a large open space to fly; you can enjoy flying in your yard or a large indoor space. 
Functions:
Extremely low CG and short main shaft design, dramatically reduces flight resistance, efficiently improves 3D performance and speed
New design linkage rod design, complete assembly increases linkage rod rigidity, enabling the pitch slider (follower) to be left out, leading to a head assembly that is much simplified and stiff
Developed specifically for DFC rotor head system, enhancing DFC linking rod's strength and decreasing linkage detachment throughout extreme flight maneuvers.
Product combination technology utilized in frames, enhancing rigidity and streamlines maintenance
New design quick removable gyroscope mounting platform incorporated with rudder servo install, efficiently uses frame?s inner space for simplified maintenance
New anti-rotation guide
Strengthened landing skids enhanced resilience
High effectiveness shaft tail drive system, efficiently increasing rudder performance and reduce power loss
Single tail belt system with the new counter weighted tail blade grips make it simpler assembly and enhancing rudder effectiveness
Utilizes dual point attachment design for absolutely no play and greater accuracy control feel
Streamlined design canopy
