I had an Excelleron year before last and flw it in Sportsman. Arch Stafford gave me a hand getting it dialed in. We put a lot of expo on the rudder and elevator to smooth them out. I had a YS 1.20FZ in mine and 16X6 prop and itdid alright in the wind after we smoothed out the rudder....it is quite an effective control surface.

If you run into Arch ask him to give you a hand, after he helped me out that plane flew much better. I watched him to run my Excelleron through the Masters sequence
