I'll make this real simple. If you were given the choice between flying a 1/4 scale warbird that weighed 55 lbs or an identical model that weighed 25 lbs which would you choose and why the choice? I started in this hobby flying a three channel glider called a "Gentle Lady" once I had glider under my control I moved on to a more advance design called the "Agila". I was fortunate to have an instructor who taught me more than just flying. He happened to be a full scale pilot. This individual new more than just flying he understood the dynamics of flight. We both were members of the "League of Silent Flight" and I still think about the times we were going for max flight durations to obtain our level three proficiency. He always maxed out my time by several minutes. We were flying identical models or so it seemed. I asked him about this and his answer was to the point. Yours weights more than mine. Takes me back to wing loading.
