Let me begin by saying I don't own that helicopter. I own several 450s but not that one. With that out of the way, how do you fly and what do you expect from the model?Back when that model was new the Scorpion 2221-** motors were popular. There are several different winds that almost certainly will meet your flying style. My 450s are old school in that I fly them using 3S 2,200 batteries. I'm very happy with that combination but the current trend is to run a 6S setup. I own the -6, -8, -10 and -12 motors. I currently have the 2221-8 and 2221-12 installed in models using 3S batteries. If you are insistent on a 6S setup you are probably looking at the 2221-1630.Again, I don't own a Furion 450 and I don't fly a 6S setup so you will probably get more valuable advice from others.Let us know what you do.https://www.amainhobbies.com/search?s=2221&fb=267&lg=fbhttps://www.scorpionsystem.com/cata...tors_4/hkii-22/"Well, nothing bad can happen now."
