Scorpion HK Series Brushless Motors are built from the best materials available, and are designed to provide both quality and performance at an affordable price. Scorpion starts with high quality aluminum alloy parts that are produced on the latest CNC milling machines. These parts are then gold anodized to provide a beautiful, long-lasting finish. The stators are made with 0.2mm laminations to give maximum efficiency, and minimum Eddy current losses. The stators are epoxy coated to prevent shorts, and are wound with wire that is rated at 180 degrees C (356 F). The magnets used in Scorpion Motors are N-50EH style, which are rated for operation at 200 degrees C (392 F), making a motor that is virtually impossible to burn up in normal use.

This particular motor is specifically designed for the new smaller electric helicopters such as the T-Rex 250, and features a 2.5mm output shaft that fits the stock Trex 250 pinion gears.

Select a color from midnight black, neon yellow, neon green, and neon orange. The colorant is made to our specifications and is mixed as the blade is created. The color completely permiates the blade, and is not painted or applied. All similarly sized blades are the same weight, allowing the user to customize their tail rotor colors as desired.

Out blades are created using a complex combination of materials which provide the perfect mix of strength and flexibility. The blades have a very large surface area yet weigh very little.

Utilizes Silicon Micro Machines (SMM) sensor with excellent stability to dramatically reduce in-flight tail drifts. Utilizes AHTCS (Active Helicopter Tail Control System) to compensate any drift caused by wind direction and force, as well as unintended yaw induced by helicopter itself during flight maneuvers. Tailor made specifically for use with high speed digital rudder servos. This gyro features high sensitivity and minimal reaction time, fully utilizing the potential of modern high speed digital rudder servos. Features 1520μs pulse wide and 760μs narrow pulse wide frame rate. Digital/Analog servo switch-able Reverse switch. Rudder servo travel limit adjustment (ATV). Delay adjustment. Gyro locking mode and gain can be adjusted remotely from the transmitter. 1.Mini/Micro heli mode, suitable for T-REX250/450(STATUS Red). Medium/large heli mode, suitable for T-REX500/600/700(STATUS Green).

The DS420 features a coreless Motor Design for fast speed, high efficiency, and low power consumption. 10 Bits signal resolution for smooth movements. Response time of 0.06s/60 deg. High strength composite alloy gears with high precision and durable structure characteristics. Aluminum alloy mid case construction for instantaneous heat dissipation, maintaining servo's high efficiency. Supports digital and analog control signal. Powerful and precise servo suitable for T-Rex 500 CCPM cyclic and rudder servo use.

Heavy duty aluminum carrying case specially designed to fit both your 250, transmitter, and even flight packs - All in the same convenient brief-case sized package. Made of impact-resistant material and ballistic foam inserts, this case will ensure safe transportation of your 200-sized heli.

This is the Zero-G CNC Aluminum skids upgrade for your Trex 250. These beautifully crafted CNC Aluminum skids are a drop in replacement for your stock Trex 250 skids. They are made from 6061 T6 Aluminum, non recycled. Besides looking fantastic on the Trex 250 they also offer more support and rigidity serving as a crossbeam for the bottom plate. These are an absolute must have for Trex 250 enthusiasts.
