You know the top half can be bought for $30 and replaced in 30m by a beginner. However something you might do is, buy the prop guards, the ones that have that part you screw down to connect the guard too? Or, for like $10 you could by those little deals that are to strengthen the arm ends, basically a flange that add some heft and keep the crack from opening. I'd buy the top, I have a bottom I never needed still sitting here.
