It looks like there's a lot of shorthand y'all use to talk about things and these are starting to appear in your tags:
Are these the best way to phrase things for a useful tag? For example, does it make more sense to have lipo-batteries (or even lithium-polymer-batteries) instead or brushless-dc?
Remember that not everyone will be using these terms perfectly so at the bare minimum, descriptions will help but I'd be happy to set up some synonyms if you all can decide what you want to be the master tag that appears on questions.
