So then who is fastet one? MEC? He did his readings with GPS as well. WITH THE SAME POWER AND A LARGER AIRFRAME. Or is someone else faster? How do these guys meassure their speeds? What is a proper measuring equipment in your opinion?
Why donīt you try it? Go ahead and build a plane with 40 in. wingspan and a 26lbs. jet engine on it. You will be surprised. Maybe I am not the first who claims to be faster then other. But I guess none of these guys put two years of work in three similar rc-planes and saw constantly increasing speed.
Read other comments about GPS. Why do you ignore them?
