Ch 23 Engine / Cowling

The subheadings below are just notional for organizing the page.  As I progress, they will be ordered more or less chronologically with pictures added as I think appropriate.

Baseline - derive from standard featherlight?:
 
​TBD.    Not sure on this yet, but thinking I may want to start with a featherlight cowling and modify?  My firewall profile is stock and I've fitted a featherlight to it in the past, as a check.

Modifications for downdraft cylinder cooling:

TBD.  Likely bulges needed for downdraft plenum near the aft most cylinders?

Modifications for oil cooler:
​    
​TBD.  Planning to build cooler in path of lower NACA.

Modifications for exhaust:

TBD.
