Tricky, isn't it. Richard Sohn N2071U ----- Original Message ----- From: "Al Gietzen" To: "Rotary motors in aircraft" Sent: Saturday, February 09, 2008 12:28 PM Subject: [FlyRotary] Re: Rotor Weight Codes the rotor is not sliding "back and forth" , it only makes a clean circular motion around its own center. The weight only is significant for the centrifugal force on the e-shaft lobe. Richard; Unless I'm mistaken, or misunderstand what you're saying; the rotor does not rotate around its own center. And the CM of the rotor does not rotate around the center of the e-shaft, but rather follows the center of the e-shaft lobe. Watch the animation on Tracy's web site.
