And, I've figured out what Chassis I'll be using.
The 1921 Oldsmobile Chassis from Granny's Hotrod. I wanted a Beefy Chassis, and my choices Are Few. The 1907 Thomas Flyer, the 1912 Stutz Bearcat, or the Olds are about all that is in Kit form, and in my stash of kits. I may test fit the Flyer Chassis, though, as the Chain Drive seems mandatory for an Aero-Engine Racer.
