Did you even read my opening post? Did you go to time 14:45 in the video and understand what I am talking about? Do you understand I am talking about the craft and the treadmill (that's plugged into the outlet?) 1. Tell me how you measure the speed of the belt BEFORE you put the craft on it? Where is the power coming from? 2. Tell me how you measure the speed of the craft? 3. Which speed is faster? Which ft/sec is greater? 4. Billvon started the conversation of power, because sometimes he gets power and speed mixed up. The title of this thread is "Faster or Slower?" The title of this thread is NOT "More power or less power?"
