Sorry I couldn't up load the video but here is how it looks in pictures. Correct me if I'm wrong. that's the 3000 turbo motor great for sniping to cqb springs. Like most, by pressing the button on the Side it rewinds the gears relieving the stress on the spring. Great gear box for beginners, easy to clean and is easy to change spring. Steal gears, will last a long time.
