I left mine alone. I have 8 flights on it as of today and will put a few more on this weekend. The first couple of flights were obviously trimming and figuring out the plane. The last 3 flights have been fine from start to finish. I think that "tucking" could be a "skill" thing.
I am running a G90 on it and it is a missle. Such a smooth flyer. Darn nice plane.
