This drive system features the EGODRIFT 4025EC Eclipse Series 570KV motor and a new front and rear mounting system for improved directional stability. Designed for 10S LiPo packs, it supports propeller diameters from 20″ to 24″ for ample F3A power. The helical Delrin gear and belt drive require minimal maintenance while reducing noise, and the motor shaft is supported by a bearing in the front carbon fiber plate. Rubber isolator mounts minimize vibration transmission, and the rear mount allows small side thrust adjustments. A spare belt is included, and total weight is 575 grams.
