There are several different types of set ups to try. Several people fly with the flaperon/spoilerons, on all the time. I prefer not to fly that way, I flip them on when I want to do something specific. Play with different things and see what you like.

As far as a Fazer.......great airplane. I find a Fazer flys better than many of the current profile planes and it's a 10 year old plane. A buddy of mine increased the moment about 5 inch's and increased the rudder as you did, powered it with a YS63 and that is a GREAT flyn plane.

Planes with longer moments (longer fuse) hover better than your typical profile plane. However different people like different types of flyn.

For your next plane........there are several great profiles out, Morris makes several or you can go to a true 3D plane. 3D plane would be like a UCD, Flip or a Laser 3D. Skip right over the Pizzaz and Dazzler.
