I have a brand new 46ax, with 4 tanks through it. I modified the muffler and am getting 15100 rpm with a apc 10x6 and 15% powermaster. This one runs better than my first 46ax. And its not even all the way broke in. What are your tach numbers?
Back in the day, 10x6 props were the standard on 35s. Today's engines are more powerful. That 10x6 is probably jest a mite bit light for that sucker.
What do you use that engine on? The use has a lot to do with the choice.
