The Scorpion HK-4525-520KV Limited Edition motor* is designed for using on 700 class helicopters running on 12-cell Li-Po power. This motor represents the most technologically advanced power source ever offered for a 700 class electric helicopter and also produces 20% more torque than the Scorpion popular HK4035 series motors and exceed 89% efficiency.
Each of the new HK-4525-520KV Limited Edition motor is wound with a single strand of 1.4mm wire for the highest possible efficiency. This motor is capable of running continuously at an input power of 4450 watts at 100 amps, and can handle peak inputs of 9600 watts and 215 amps for 2 seconds
Scorpion Competition 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 Electro-Plated 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 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. However, due to the high RPM of these motors, and the fact that we cannot control the installation and setup, the bearings are not covered by the 2-Year warranty, nor is any subsequent damage caused to the motor by a bearing failure. Bearings are a normal wear item, and as such, need to be maintained and changed periodically. For maximum life, make sure that a sufficient gap is left between the pinion and main gear during motor installation to avoid binding, and put a small drop of oil on each bearing every 5-6 flights. It is the responsibility of the pilot to ensure that the bearings are maintained properly.
For the best overall combination of quality, performance, and value, uses Scorpion Motors in your helicopter!
