Hi,
The Fokker Triplane is great! It is the Great Planes Fokker; about 60" wingspan, and it's got one of my Echo/Kioritz 23.6cc engines in it, swinging a wood 18 x 6 prop. To me, the sound is more scale than a glow four stroke, and the Echo pulls the airplane around in a decidedly "un-scale" manner. At least that's what a friend of mine said when I was wringing the plane out one day. I told him "Hey, how do you know? You weren't there in WW1..."
