I have a MDS 2.18 engine that will be going on a 72" Katana. I need a 20x6 prop. I was thinking of getting a Top Flight, Zinger, MA, or APC. That do you guys think? I am new to 3D flying and was wondering what you guys recommend. Are there any other props that I should consider?

Thanks Keep the adive comming it is greatly apreciated.
