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. All Scorpion HK Series 22mm motors come with 3.5mm male Bullet style connectors already attached, and include a hardware package that contains 3 matching female Bullet connectors for your speed controller and a cross style backplate mount with 4 screws. Since the HK series motors are primarily designed for Helicopter and Ducted Fan use, they do not include a prop adapter. This motor is specifically designed for the newer micro helicopters, such as the Gaui 200, that require a 2.3mm output shaft.

The Precision Main Blade Grips and Mixing Arms are designed to work on the new EP100 and Hurricane 200 helicopters. The product is 100% aluminum CNC machined to provide best precision and durability. With total of 8 miniature ball bearings, this combination works flawlessly on the blade EP100 head, and brings much better smoothness in the head response. The mixing arms are redesigned to equip with high precision bearings in each arm instead of brass washers to provide super smoothness and eliminate all unwanted flops. It is design to fix the problem of the stock mixing arms with longer theaded at ball links to prevent metal ball thead broken.

Moreover, the light and stylish high quality aircraft aluminum blade grips can help reduce the flex in the EP100 head and improve cyclic response on the EP 100/Hurricane 200 helicopters.

The new designed Tail Pitch Slider will reduce most of the slop in the tail while providing best accurate control for the EP100/Hurricane 200 tail system. All tail pitch slider arms are made of cnc aluminum for best accuracy. It is also very light in weight and strong. With dual precision bearings built in, the unit gives best precision tail controls and smoothness. The Tail Pitch Slider is designed to improve tail controls performance on Hurricane 200 helicopters.

The Precision Tail Set PRO is a new design from MicroHeli to deliver better tail smoothness and precision on Gaui EP100 and Hurricane 200 helicopters. With total of 14 precision bearings in the tail system, this is absolutely the best tail system for the EP100 available on the market. It differentiates itselfs from other designs in many ways: The new design hinged type tail pitch slider offers dual support positions on both sides with dual ball bearings connections to ensure total fitness and absolute slop free connections. The tail pitch slider itself also is equipped with double precision bearings to ensure slop free and great smoothness. The brass sleeve in the tail pitch slider is done on highest precision machine with tolerance of +/- 0.001mm so that the tail pitch slider always move truely on the tail shaft. This will ensure absolute slop free in all 3 dimensions. The new arms now no longer uses plastic ball ends to connect to the tail rotor but using two precision miniature bearings for precision control. It is a big improvement over stock design which has plastic ball end connections that can wear out over time. All the bearings we are using in this tail PRO are smallest types of bearings on the market. Over years of bearings selections, we can offer smallest precision bearings for lightest weight and great look. This advantage helps reduce the weight to minimum while maintaning superior performance and great outlook. With a fast look, it's hard to believe they are bearings included. Overall, this tail set PRO provides super smoothness and zero slop, zero binding solution for the tail. It is preassembled at manufacture to ensure all components are working well together and offers extremely easy assembly process. It takes virtually a minute or two to assemble the tail blades and plug the whole system into the tail boom and ready to enjoy the smoothest tail. Only owning this precision system that one can appreciate the performance and the unique look that the system offers.
