What made you decide to put a US 41 on it? I have always thought this engine was better suited for a piper cub, warbird or non aerobatic type plane. I have never owned one but have always heard they were heavy on weight and light on power. Have you flown it yet I would be interested in a flight report. What is the quality of the ARF? It looks really nice. What is the weight with the US 41 on it? I was looking at getting one but went with the Dave Patrick Edge 540 instead. I am thrilled with my DP Edge.
