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

This is the Align T-REX 250 Pro DFC Combo Helicopter Package. This combo package consists of 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 main 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 exact flying reaction, with outstanding high speed efficiency. The frame structure utilizes product combination techniques, allowing ideal assimilation between plastic alloy with carbon fiber, maintaining structural rigidity while simplifying maintenance. A unique integrated gyro/servo install enables fast elimination, simplifying maintenance while keeping a clean overall visual appearance. An effective shaft drive system effectively minimizes tail power output loss and the tail transmission is an integrated system with an upgraded rudder control system, with solid building and absolutely no slop, resulting in a more exact control feel.
Although the T-Rex 250 PRO DFC is small in size, it?s packed with efficiency and is capable of performing any hard 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:
Extremely low CG and brief main shaft style, dramatically minimizes flight resistance, effectively improves 3D efficiency and speed
New style linkage rod style, total assembly increases linkage rod rigidity, allowing the pitch slider (follower) to be left out, resulting in a head assembly that is much streamlined and stiff
Designed particularly for DFC rotor head system, improving DFC connecting rod's strength and decreasing linkage detachment throughout extreme flight maneuvers.
Product combination innovation used in frames, improving rigidity and streamlines maintenance
New style fast detachable gyroscope mounting platform integrated with rudder servo install, effectively utilizes frame?s inner space for streamlined maintenance
New anti-rotation guide
Enhanced landing skids improved durability
High efficiency shaft tail drive system, effectively increasing rudder efficiency and reduce power loss
Single tail belt system with the brand-new counter weighted tail blade grips make it much easier assembly and improving rudder efficiency
Utilizes double point accessory style for absolutely no play and greater accuracy control feel
Streamlined style canopy
