Well the truth lies in putting the plane on a diet. I was very weight conscious this time while building. On my first build I was not really concerned about weight (don’t really know why) and wound up with a heavy KR. She flew great and I wish I still had her. Anyway I built the top half of the fuselage using prefab KR parts (turtle deck & front deck) which were my biggest weight savings plus I designed my seat this time which lowered the overall height of the fuselage by 2 1/2 inches. That also helped reduce weight. I will reveal other modifications when I get to the gathering.
