Was spinning a 11x6. It's what I started with on my fx, then I switched to a 12x4, then the fx died and I started my new ax off with the 11x6 to break it in. I'm just amazed at how differantly it flys. It's like a differant plane with the 12x4. I mean everything feels differant about it. Not just landings but turns everything. Really is amazing
