What, if any, are the advantages in mounting the engine where the muffler is below the engine? Is it for balance, so exhaust won't be at wing level, or just for looks? Plane in question is a 40 size big stick type. My 40 size stick has muffler below, where as a 60 size stick I have has it at the side. I gots to know.[:@]
I'm just getting started into r/c planes, ( have cars, trucks, and sailboat), so ya'll get ready for lots of questions from me!
