Let me add in here. I have an Evo .46 I run mine on 10% nitro (Byron fuels). If you do get one, by all means take the silly little ring off of the low end needle. My Evo had the low end needle completely closed upon new. Its supposed to be an adjustment threshold so you don't screw up but its really a hinderance. I'm thinking about another Evo, a .61 size (I can get new for $99) for a U Can Do 46 plane. The engine in it gets mounted upside down. Remember, these engines are made in China and who knows where they had the settings at. Supposedly, these engines are broken in at factory.
