I will go out on a limb here. The DPM Ultimate 1.20 has two 60" wings, flies really tamely on low rates with a smaller engine, and goes balistic with a big engine on it. Its a little bit pricey, but well worth it. It flies like its on rails. Come to think of it though, its more suitable for a 4th airplane, but just keep it in mind. My favorite airplane by far and it was my fourth plane. Picked it up easily after flying my GP Ulty around (another really nice flyer). One thing is definately for sure though, BIG AIRPLANES DO FLY BETTER. They are easier to see, fly better in the wind, and just are super fun.
Just my .02 cents.
