Electric Tow Bar for Planes

This is a DIY battery-driven electric tow bar for small planes.

The commercial ones cost way to much and this one you can build for under $150 USD.

The first part of the build you can watch here: https://www.youtube.com/watch?v=7iESRna7VRM&feature=youtu.be

I will upload the other videos in a couple of days.
