RE: Anti Yaw Device
This reminds me of the reasoning for why some guys automatically crank in some right thrust...because just a tiny amount of left thrust [accidentally] is so detrimental. I guess if you could pick a side to be off lateral balance wise, the starboard side is much better than port.
Control line flyers have known about and exercised good lateral CG hygene for decades.
After reading the article word for word for about the first paragraph, they began to lose my attention once I got the feeling that they were reporting about some kind of panacea or magic elixir. I'm kind of surprised that MA ran the article in that light, like they had just invented a glowplug that never burns out.
