How the 3D Maneuvering Gear works?

I have been a fan of Shingeki no Kyojin or Attack on Titan for years and this anime never disappointed me. I really love how the story told and Isayama's great skills in thinking on how it will turn out to be. I was amazed how the characters used their 3DMG in the series so I tried to think the most possible way on how they use this gear that can be applied in real life. 

I posted a video in my Facebook Page about the explanation about 3DMG.
TAKE NOTE: THIS IS ONLY A THEORY AND NO ONE FROM THE STAFF OR ISAYAMA ITSELF ACKNOWLEDGED THE THINGS THAT I SAID IN THIS VIDEO. Except from some ideas from the manga.

By the way, I am now celebrating my first year anniversary! I hope the readers from this blog are satisfied in every blog I post. I will be posting more cause I won't be stopping from being an otaku! Love lots!
