Charley, I dont mean to be stupid, wait a minute, cancel that! How do you set your high speed needle? I just came from the field and it took a lot of encouragement to get the Tower .46 to fly reliably, but when I got it man alive, she flew like a champ with an 11X5 prop, it sounded like it was over-reving in the air. I don't know what you think but I am going back to the 11X7 prop to make the plane jump up off the ground and it will still turn 11,000 RPM'S at around 320 feet above sea level, slow and Harrier just fine. I never should have experimented with different props but you never know until you try.
