Thank you for viewing! m(_ _)m This is a TACHYON electric radio-controlled car amplifier from KEYENCE. It's a used item that was used for drifting, so please check the images. I haven't used it in several years, but I confirmed its operation for this listing using a Futaba transmitter/receiver, a KEYENCE TACHYON amplifier, and a KEYENCE LUXON 8.5t motor. Type: Parts/Accessories Genre (Radio Control): Drift Car Scale: 1/10
