Why would one fly more like a real plane than the other?
fwiw real planes (Cessna class) never have the power-to-weight ratio of a gas R/C plane that we're spoilt with. Many basic brushed electrics have basically similar performance to real planes, and you have to "fly on the wing", not the motor/engine. With brushless and a lightweight R/C electric plane (you don't have to beef up an electic plane like a gas plane, saving quite a bit of weight), which is off-set by battery weight (unless you consider Li-Poly cells) will easily give you similar gas performnace and more.
Then there's Reynold's numbers to deal with when you scale down a plane; a 42" plane will never fly "more like real planes".
