Not something I want to find out on short final, so I'll continue coming in hot until I know more about it's slow flight characteristics. I was able to come in slower in my LongEZ, but only after getting comfortable with it's slow flight characteristics and canard stall speed. I will be able to decrease my approach and landing speeds once I have done further flight testing....especially at slow speeds. Unfortunately, I have been concentrating more on obtaining high speeds. I have been increasing cruise speeds 5 knots at a time, watching for any signs of flutter, of course. Knock on wood, all seems fine so far. I will take her to higher altitudes and explore the other end of the envelope soon. Take care.
