Yes it's considering the weight of the battery, as well as the weight of the motors. It doesn't factor in the props, I didn't get around to that. The props have inaccurate geometry of course, which I'm looking to fix with a mesher.

Have a look at the console for how the geometric program is assembled.

Cool. I think this tool has a lot of potential users, especially if you can make it pick between commonly available props, esc, motors and so on. Imagine how cool this would be if it could make a list of those things and export a 3d-printable frame :)
