thanks rcplanenut! The plane is overpowered in the extreme. I had the 1.6 lying around and just tried it. I will have to say that compared to the os91 4stroke that was on it it really pulls, there is no comparison. The extra nose weight was needed (at the time) because i only had these big hitech metal gear hight torque servos on the rudder and elevator. The cg came out perfect with no extra wieght added. Back to the props do u no anything about this "W" designation? Are the W's really better for high alpha flight???
