Description
The ALIGN T-REX 300X Super Combo w/ A10 Ready to Fly (RTF) – RH30E01XW is a complete helicopter package designed for direct, responsive flight—built around the T-REX 300X DFC rotor head and a flybarless MiniGRS system for solid control feel and consistent performance in both indoor flying and outdoor 3D.
This RTF kit is built to be “charge and fly” right out of the box. It comes with the A10 radio control system plus a MiniA.BUS receiver, along with the electronics needed for operation, including the RCE-BL25A 25A brushless ESC and the 300MX brushless motor (3700KV/2216). For control, it includes three DS450 digital servos for cyclic and a DS455 digital servo for the tail, supporting high torque response with metal gears and a robust servo case design.
The included power system uses a 3S 11.1V 1300mAh (30C) battery (XT30) and a balance charger (RCC-3SX), so you can charge and get back in the air quickly. The model also includes 230mm carbon fiber main blades and 50mm tail blades, with flybarless programming handled via the MiniGRS dials and transmitter.
