I too had the same thing happen (I've got a Saito .72 on mine. In stead of just replacing the cracked piece I went ahead and put a DuBro soft mount on mine. It added some weight to the nose but I was able to copensate by moving my battery pack to the back of the compartment above the wing....I still have a perfectly tail heavy plane that flys just as crazy.... and so much smoother...I was pretty skepticaal of the stock mounting system when I first assembled my Pizazz.
