Updated on Jun 7, 2026 06:32:17 PM

This is the Align T-REX 250 Pro DFC Combo Helicopter Kit. This combo kit 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 equipment for the T-Rex 250 Pro DFC, the popular DFC head provides a low CG and low wind resistance for direct and precise flying response, with excellent high speed performance. The frame structure utilizes material integration techniques, allowing perfect assimilation between plastic alloy with carbon fiber, maintaining structural rigidity while simplifying maintenance. A unique integrated gyro/servo mount enables quick removal, simplifying maintenance while keeping a clean overall aesthetic look. An efficient shaft drive system effectively minimizes tail power output loss and the tail gearbox is an integrated unit with a redesigned rudder control system, with solid construction and zero slop, resulting in a more precise control feel.
Although the T-Rex 250 PRO DFC is small in size, it?s packed with performance and is capable of performing any difficult flight maneuvers. No longer do you need to find a large open space to fly; you can enjoy flying in your backyard or a large indoor space. 
Features:
Extremely low CG and short main shaft design, dramatically reduces flight resistance, effectively improves 3D performance and speed
New style linkage rod design, complete assembly increases linkage rod rigidity, allowing the pitch slider (follower) to be omitted, resulting in a head assembly that is much simplified and rigid
Designed specifically for DFC rotor head system, improving DFC connecting rod's strength and minimizing linkage detachment during extreme flight maneuvers.
Material integration technology used in frames, improving rigidity and simplifies maintenance
New style quick removable gyroscope mounting platform integrated with rudder servo mount, effectively utilizes frame?s inner space for simplified maintenance
New anti-rotation guide
Strengthened landing skids enhanced durability
High efficiency shaft tail drive system, effectively increasing rudder performance and decrease power loss
Single tail belt unit with the new counter weighted tail blade grips make it easier assembly and improving rudder efficiency
Utilizes dual point attachment design for zero play and higher precision control feel
Streamlined design canopy
