Impressive 224:1 gearmotors are very comparable to a hobby servo for power, at a fraction of the cost! This motor offers 50 in*oz of torque, rotating 360 degrees every 1.6 seconds (38 rpm - just a hair slower than a servo), at 5V, drawing 600mA at stall (free running at 52mA.) Has a 7mm double-flat output shaft for use with the Wheel Watcher Gearbox Wheels and a built in clutch (limiting at 60 in*oz, but easily "locked"), and mounting screw holes! Straight: Overall dimensions are 70mm (2.76") long x 22.5mm (0.886") x 37mm (1.46") including output shafts, while only weighing 37grams( 1.31ozs.)
