I am looking for the definition of a profile model as applies to profile stunt events. The AMA definition is a bit vague.

You might want to read a recent thread in the Rules section of this forum. That has a discussion on rules for profile stunt models. (It does not get into the subject of "Profile Defination", but might be close what you are looking for.
From that thread is a post:
"There are no rules in the AMA rulebook for "Profile Stunt". The AMA rulebook does give in the CL General section a "Profile Definition" but it is not specific to any stunt event."

This is all I found. It's British.

"The" definition depends on where you live, because (in the US at least) the profile events are all local.
This was all flogged to death recently in the rules section, as Kieth mentioned. http://stunthanger.com/smf/index.php?topic=28905.0 (http://stunthanger.com/smf/index.php?topic=28905.0). Lots-o-comments.
I'm not going to take the time to look, but I thought the AMA definition was more spare than vague: the engine needs to be exposed from lugs to plug (well, "crank centerline to head", but that doesn't rhyme), and the fuselage behind the trailing edge needs to be no more than 3/4 of an inch thick. I take that to mean that beyond those restrictions, anything goes. If you need more, write it into the rules for your local event.

I think that the definition (above) is in either (or both) the Scale or Navy Carrier sections dealing with those profile events.
Dave Gardner pretty single handedly wrote the NW P.40 rules, and said he got that wording straight from the AMA Profile Scale rules, anyway. Later we dropped the displacement regs and made it NW Profile Stunt, to be more inclusive and less exclusive. 8) Steve

To all, if you find a definition of a profile in the Precision Aerobatics section of the rule book let me and others know.
