Today I picked up my DLE30 and wow is all I have to say. I saw the O.S. gasser today too and I want to build a plane just to fly that. beautiful! I think O.S. will build all size gas engines in the near future and when they do, I'm getting one or two. Picked up spektrum 6020 servo's too so the plane is coming along. Was told though a smoke system would probably be pushing the limits of the wing load. Bummer!
