RE: Why the near obsession with over powering airplanes?
Ihave done a lot of messing around with different wing loadings on the same airframe, easy to do with an electric, you just increase the battery size and have always found the lighest wing loading a more pleasurable flying experience given "proper" power. Just my opinion.
That said I do like she smallest lighest most poerful combo for my glow engine planes. for example Ihave an Irvine .25 which is a very strong runner on my Sonic while Icould easily have gone with a Thunder Tiger GP25 which while being a very reliable engine is not as high an output engine.
