The Scorpion HKIII-4020 Series Motor is designed for using on 550 class helicopters running on 6 to 8-cell Li-Po power. This motor represents the most technologically advanced power source ever offered for a 550 class electric helicopter.
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.
Included in the Box
Rudder Servo Mount
Align RC 55H Engine made in Japan and suitable for superior 55 size helicopter.
Jeti OPTIC 8 provides absolute isolation of the RC receiver from other electrical equipment in the model. The OPTIC 8 prevents unwanted signals moving along conductors from servos, speed controllers, and other devices connected to the on–board electrical system.
Using the OPTIC 8 allows greater flexibility over receiver placement in the model. The quality of incoming signals is mainly influenced by the direct contact of the receiver with cables and other electrical equipment – which is completely electrically isolated when using the OPTIC 8.
OPTO isolation of the receiver (using the OPTIC 8) is recommended when using five and more servos; for ELECTRIC drive, more then 50A and greater than 10s NiXX or 4S LiXX cells using Switch Mode (Switching) BEC circuits.
