Hi all , I would like to know if its feesible to put a gasser engine in a 78" edge 540? I wanted to go gas to lower the flying cost and have been advised against the gas engine due to its weight. The airplane recomends a 1.08-1.50 2stroke or a 1.20-1.80 4 stroke. Will a gas engine work or will the airplane be too heavy to fly properly? Thnaks
