Hello Michael, I flew the original Tutor in beginner and right up to intermediate. I learned many things from flying this plane. Like yours, I had a Fox.35 on mine as well. On nice mild days it was a joy to fly. Once the winds started bouncing it around, it was time to park it. I didn't build my plane, I actually rebuilt it. That being said additional wood and adhesive and paint probably had mine in the not so favorable weight zone. The Fox was working hard to keep up. The Tutor's wing could certainly use improvement. Since we obviously can't change that we have to keep it flying steadily through the maneuvers. I subscribe to the big plane, big prop theory. A 10x6 worked well , although it could also be improved with a 10 x 5 . If your using the stock muffler, it may need modification and or a tongue. You have to get rid of that heat. This will certainly have a affect on what props your swinging. I found that eliminating the rudder offset and swinging the leadouts fwd. really gained the speed needed to fly through the maneuvers steadily. This plane taught me about yaw and how it affects your fuel tank. Getting rid of all the drag being created by the plane trying to fly out of the circle vs with the circle allowed my props to work a whole lot better. Ken
