He does have allot of good points, I was just kidding a little! All my 40 size do have a 45 or better but that is because I fly at 7000 ft and the extra power is needed! I even have a couple sixty's on some forty size. A sixty size plane is just about my limit because of the size of my shop and hauler. but even some of my sixty's have ninety's on them. I do love to build but do take the fast way out with an ARF. I tend to buy Arf's in the spring and summer and kits in the fall and winter! I am learning but need to learn allot more, and know I will be in this hobby as long as my health will let me! I love this hobby and know that I will someday when have more space will go a bit larger and all gas due to the price of glow fuel, but am loving they are building smaller gas engines for smaller planes!
