The Packaging and Box

Inside the box you’ll find the Yelangu L4 Autodolly unit, remote control, USB charging cable, spare battery, allen key, spare rubber o-ring for the wheel, instruction manual and warranty card.


A Closer Look

The Yelangu L4 Autodolly is constructed of high quality Aluminum. It feels pretty robust and solid in the hand. The compact size means that it’s portable and you can easily travel with it.

The foldable wheels can be adjusted to give you various recording angles. Position the wheels in a “T-shape” to capture recording in a straight line. Angle the wheels out (bottom middle photo) for slower speed curved recording, while wheels angled inwards (bottom right photo) will give you a higher speed curved recording.

The unit features a built-in rechargeable battery. Use the included USB charging cable to charge the unit (6 hrs charge time). A full charge will give you around 6 hrs of usage. There are are 3 speed settings… Fastest Speed: 2.5CM/S, Middle Speed: 2.1CM/S, and Lowest Speed: 1.7CM/S. 

There are also 2 screw threads (1/4 and 3/8) which allow you mount various recording devices. The included adapter/transform screw comes in handy.


Final thoughts

This is our first toy/gadget of 2018 and I’m super pleased with it. I can now get some great scrolling video footage for our vlogs and unboxing videos. What’s even better is that it comes with remote control that allows you to start/stop as well as forward/reverse the movement of the dolly. 6 hrs of usage from a full charge is more than enough.



Another thing I like about the Yelangu L4 Autodolly is the compact size and its light-weight. This means it’s really portable and you can take it with your travels.

I tested it with our Canon M6 mirrorless camera and an iPhone 7 with no issues at all … and the video footage I got is just amazing.
