My f90 has this "balooning" effect that everyone is talking about, but who cares. It is still a *****cat to land and it flys very well in all other aspects. My suggestion to everyone that this bothers is to add a few clicks of down elevator on landing or just get used to it. I.e... don't modify the plane just to make it land a little better. It is easy enough as is, so why compromise flight characteristics. I love this plane, as much as one can love arf's anyway.
