Acuvance Trace Bector is a revolutionary upgrade of the Chevalier Trace receiver device. It enjoys a larger capacity, lower resistance, and higher efficiency than its predecessor due to newly-engineered circuitry. Thanks to its unique design with relay system male and female connectors, BECTOR is easy to install and offers flexible mounting. Installing it between the receiver and the ESC, or between the servo and the gyro can help to stabilize the whole electric system. With two BECTORs, you can attach it to both 1 and 2 simultaneously.
