<DIV>Remember that this is gas engine. However, I will use you idea in my plane. I am using the OS160 in my ABBRA.</DIV>

<DIV>Thanks much,</DIV>

<DIV>I save 3/4 oz. buy changing the propnut, washer and spinner jam nut to a lighter configuration on my OS 1.60 setups. Used a grade 5 nut from a hardware store, with a Dave Brown short spinner adapter with the waher that comes with his adapter. The OS stuff is HEAVY! Also used the light backplate.</DIV>
