Stec, part numbers 0109-11, 0110-7, 0103-1, 6405-14L plus roll and pitch servos, 0111-. Wire and connectors included. November 1989 build date. Condition unknown, this came with a unfinished Glasair 3 project. 14 Volt. Very clean, no obvious damage, apparently the last owner was going to use this in the Glasair so I assume it functions.
