        RGG1002 Rather Good Guide for Comparing Certain LiPo Batteries

        RGG1002 Rather Good Guide for Comparing Certain LiPo Batteries

        [Please note: The document you will download is just a single page placeholder. The real document will be emailed to you and is 10 pages long.]

        With so many different lithium polymer (LiPo) battery vendors producing so many different batteries for use in multi-rotor helicopters I found it hard to know which of those LiPo’s would deliver the best performance for use in the Cinestar 8 that I fly.

        What I wanted to do was select the best LiPo battery; that is, the one that would provide the most usable power to give the Cinestar 8 the longest flight times.

        This is a multi-dimensional problem involving such factors as the battery’s weight, the actual electrical capacity (as distinct from the manufacturer’s claimed capacity) and the actual discharge capability (again, as distinct from the manufacturer’s claimed capability).

        But how could I do a proper side-by-side test? Actually flying the batteries on the Cinestar would rely on some assumptions about having identical flights under identical conditions to provide any kind of useful conditions. I tried flying the Cinestar indoors, hovering the Cinestar about eight feet off the floor, but even then, I could tell I was getting significant variations in flight times (apart from it being exquisitely boring).

        So, in the best tradition of Baldrick, I devised a cunning plan. This is a Rather Good Guide™ to the results.
