Karearea Talon and ZMX Finx30: is the hype real? The Talon racing quadcopter frame has vertical arms, which promise less drag and more speed. The Finx30 motor from ZMX has a patented magnet design that is supposed to produce more power for less weight. In this flight review, I'll tell you my opinion of these claims. And... spoiler... yeah, it's not all hype.
