Sale price$438.38CAD


The Scorpion HK-4530-450 motor is designed for using in 700 class helicopters running on 14-cell Li-Po power. This motor represents the most technologically advanced power source ever offered for a 700 class electric helicopter, and produces 20% more torque than the popular Scorpion HKIII-4035 series motors with over 90% efficiency.

Each of the new HK-4530-450KV Limited Edition motors is wound with a single strand of 1.4mm wire for the highest possible efficiency. This motor is capable of running continuously with an input power of 5400 watts at 110 amps, and can handle peak input of 9600 watts and 200 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-Coated 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 custom manufactured to be able to withstand high temperatures, 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, use Scorpion Motors in your helicopter!
