RE: Why the near obsession with over powering airplanes?
When you buy a plane that is underpowered, you fly it at full throttle all the time. When you fly at full throttle all the time, you wish you didn't have to. When you wish you didn't have to, go go out and spend even more of your precious money on a bigger engine. Don't spend even more of your precious money on a bigger engine. Buy the big engine at the start instead of the small one and be a happy pilot who still has money.
^^^that is my philosophy on the subject.^^^
