Martin,

I need to dig out my OS .10 and the ASP .12 to see if the heads will interchange. Being a .12 the ASP may have a slightly larger hole to fill. I like the idea that the ASP has a ball-bearing crank.

Hey, maybe Norvel will make an .09 or .10.....that should be a winner from the get-go.

Just stopped by a hobby shop in Sanford, Fl and picked up a quart of Norvel NVX 25% nitro fuel.
They also had a DU-BRO Norvel Aluminum Spinner prop nut for starter cone. It's about 3/4" dia.

Don't know how soon I can get to firing this baby up....too many irons in the fire.

Tried to find a Cox 7" X 4" but the hobby shop didn't have any. I have some Taipan, Top-Flite, Power-Props, Master, Zinger and a few others in 7"X 4" so I'll take some readings after it's broken in a bit. I have a feeling the Cox Prop is what I want.

I like this chunky little bugger, can't wait to run it.
