A powerful high specification digital sail winch servo with metal gears that can be programmed to operate from 1 to 6 turns (controlled by end point adjustment). This sail winch servo can operate up to an impressive 14.5kg cm of torque so it is perfect for heavier applications.
This HiTec servo is a multi-turn servo winch. Depending on the RC system used, you can get up to 4 full 360 degree revolutions of high torque out of this servo.
SparkFun's minimal design approach to Arduino. This is a 5V Arduino running the 16MHz bootloader.
Ready to ship prebuilt tracked platform with DeWalt battery adapter. This lightweight platform uses IG42 122 RPM motors, all-terrain tracks, and an RC control system. Powered by standard DeWalt batteries for ease of use.
