It is great. I have a Brison 3.2 on it. It is very aerobatic. No bad tendencies. It will glide forever. I had a dead stick the first time I took it out. I did not think it would make it back to the runway, but it not only made it back but over shot the runway. I have never seen a biplane glide like that. The only complaint is the landing gear is not quite heavy enough for the plane. After a day of touch and goes I have to take it gets a bit flat. Other than that it is the besst plane I have ever had.
