I posted because it is interesting. A cold beverage would be easy to do huh. All one needs is a fixed beverage hammock on the bottom.It's definitely struggling to lift that small of a load... If done properly, I could see it being used to transport a beverage a short distance away, that would be pretty cool. The first thing to consider is that lifting anything will require it to be as close as possible to the CoG and it needs to be rigid.
Over the weekend we found out one of my son's friends was sick, so we put together a small bag with cookies and a get well card and delivered it. Very light load. No problems other than wind and depth perception.
