ACE RC ESC-50 allow remote control of airborne electric motors from and RC System. It features the latest all-solid state Integrated Circuits, and is capable of supplying up to 50 Amps of continuous motor current. It is extremely small and lightweight, and fits most airborne installations. Its integrated Battery Eliminator Circuit ( BEC ) powers the receiver from the motor battery, with automatic cutoff of the motor power to preserve receiver power as the battery becomes depleted. Its onboard microprocessor requires no programming, and has built-in safely features to prevent accidental motor startup on powering up.
