All Flex Drive Lengths are compatible with any system except the gasoline powered VMG-1750BP & VMG-2500BP. A 7' flex drive or longer is recommended to be used with the backpack units. You need enough of a loop in the flex drive to reach the back of backpack were the motor is. Flex Drives come in 1', 3', 5' , 7', 10', 14', & 21' lengths. Two flex drives can be coupled together to extend the length using the Viber VCP Coupling. The standard Flex Drives are 1 1/16" in diameter. There is a 7/8" diameter flex drive for the 7/8" Head.
