I agree with the recommendations to add incidence adjusters to the Integral. It flies well at the factory settings, I flew it that way for a year. When I got trying to eliminate the mixing for knife edge, etc, I added adjusters and the plane felt much better at all speeds. It isn't hard, there is even an article on how to do it in the Kfactor about 2 years ago. If you can't find it, let me know and I can probably find the article for you. It only takes a couple hours to complete the task.
