I love my Pizzaz.Mine has an OS 91 four stroke and does great.I don't know what it weighs or waht the CG is,but I put one elevator servo on each side in the back,one rudder servo with a pull-pull set up, and a 1650 nimh pack stuffed in the trailling edge.However mine also falls off to one side after about two torque rolls.It hovers pretty well I don't know how long but it's not bad.Flat spins are great,knife edge stalls are great,Blenders or so-so.Elevator not so good either.Walls are also great.It's the only plane I have that I will touch the wheels on the runway and pull up into a hover,with the .91,I just gas it and it pulls straight up out of any situation.I am building a Magic right now so I will see how it compares.
