The Griffon Manual Control System is a line-of-sight control system designed and manufactured by Griffon Aerospace. The MCS 400 utilizes a COTS Futaba T10CAP controller to send commands to the  air vehicle. The commands are eventually amplified and transmitted through Griffons RFD on military frequencies between 360-400 MHz. The MCS 400 is capable of transmitting at up to 10 Watts providing over 25 miles of operational range.
