Ah go for it Andy....
I've got the AeroWorks Mustang with Sierra gear and a DA-60, it's cool but it's not a Corsair.
I took my Corsair down to a builder/friend on Monday and they (another friend/builder) were really impressed with the FG-84. They each have one of these Corsairs and I looked at one of them with the seven cylinder glow radial. Absolutely COOL..... lol
My engine won't look that nifty, but I'll swing that Biela semi-scale three bladed prop with authority....
