This cowl model looks a bit too high. Can you give me the dimensions
on the height of the center line of the cowl at the firewall
Charlie? Also this is a 12" spinner so correct me if I am wrong
on that. I did not model the air intakes as that would require
a lot more cross sectional data up near the spinner.

It is a 12 inch spinner.

I'll get you the firewall height when I get home tonite.  It doesn't look all that bad Paul.  The cowl has a recess built in at the bottom for exhaust to exit so that blister adds several inches to the overall height that is not present on the firewall.  I'll give you the overall firewall height and then reattach the lower cowl section and get you the overall length from the top of the firewall to the bottom of the cowl.  However, if you created the model based upon the data at the 21 inch line, it has to be correct to no more error than a couple 16ths of an inch.

When I get that adjusted this will be good enough to check for motor mount
and internal muffler fits. With a bit of cross sectional data I can do this on 
any kitplane cowl.
