The evil kind from ****. Seriously, this is something I thought about as well, but I wanted the flight characteristics of the Plus more than the added power. I would question if the main board ESCs are up to the task. It also occurred to me to try just the longer arms with the 480 motors spinning the bigger props. Was going to try that on Frankenphoon, but lost interest when I got the Plus.I dunno, stuff like that really intrigues me. For instance, if I put 520 arms and motors on the 480, what kind of Frankenstein would I get?
