Looking for a Nexa Twin Otter

Nevermind.

Hmmmm. I have the flightline fw190 power sytem I am thinking about using in my otter. It moved the Black Horse He11 around pretty well. My question is the prop shaft has a special square deal that locks the backing plate in. Is there another prop shaft that is 4 bolt that I could but on this motor so I don't have to use the flightline prop and spinner set? The motors are 3648-830kv.
