I'm researching my second plane (flying a hobbyzone super cub now) and I have a stupid question about electric engines.
I'm looking at two planes, one has a "15 size brushless outrunner motor" and the second has a "480 size 960kv brushless outrunner motor". Which is more powerful?

Does anyone have a chart they can post or a link to a list of engine sizes and their power output or list them in order of least powerful to most powerful?
