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. Scorpion Motors are built to last, and are backed with a 2-Year warranty against defects in materials or workmanship. For the best overall combination of quality, performance, and value, give Scorpion Motors a try!

Hyperion H3025 Outrunner Motor Series, for all aircraft, but designed especially for RC helicopters such as Hirobo Lepton. H30 motors weigh 186 grams including cast aluminum cooling fan and 3.5mm Gold connectors pre-soldered to the motor wires. Female 3.5mm connectors and shrink tube come included in the package along with 4 M3 screws. Note: Unlike the airplane-specific Z30 Hyperion motors, the H30 Series motors have both sets of mounting screw holes with 25mm spacing (Z30 have one set at 19mm spacing, one at 25mm). The most popular installations of the H30 motor is in the Hirobo Lepton Heli, with H3025-10 motor on 4S 3700-4200mAh battery and stock pinion gear. Some also use the H3025-08 in Lepton as a 3S motor, or on 4S with appropriate gearing. Both the 8T and 10T versions of the motor are also good for model airplanes, especially when extra cooling is a concern.

This is the newly developed 650L brushless motor with higher efficiency and higher toruqe. Using a 6S Li-Po battery there is a 30% torque increase! The new motor features power-saving for general flight and sustained power-output for extreme 3D flight. It is assembled with Japanese made high-speed ball bearings and utilizes a powerful magnetic outrunner rotor. These new brushless motors are designed with a new radiator system, an integrated cooling fan and has air ingress/egress vents for circulating cool air inside the rotor continuously delivering increased perfomance with decreased operating temprature.

This motor should be used for serious aerobatics and extreme 3D. It will offer lots of power without comprimising flight time. Hackers are a drop in replacement.
