Paul,
That drawing looks great. I've been trying to get the
dimensions of the cowl from Mustang Aero and the
Mustang group without success. The cowl itself is not
on any of the plans but the dimensions you have seem
to be the best so far.
The only problem we have is that directly behind the
firewall we have the main fuel tank. In this case, the
slide throttle is not a direct shot unless we can
build additional linkage.....
I'm also going to talk with James Aircraft and see if
they would be interested in adapting their Mustang II
cowl with their alternative cowl for this application.
I think your drawing should be a big help too.
Mark
I don't think a linkage would be a big problem.
You could use an ordinary push pull throttle cable
or a rocking beam. All we need is two inches of
slide travel. Move the throttle over and down to a
center tunnel
on the right like an airliner or off to the left like
a J3 Piper Cub.
Let me know if Will James needs section curves to
build
a cowl.
I can do several iterations until every one is happy.
Also Will, any section curve spacing is possible. What
ever you
need to build a buck.

Thankyou Paul, your generousity is apprerciated. I have
not had direct comm with Mark as yet, but look forward
to understanding his time frame and specific needs.
Will
Will you have a booth at OSH this year Will?
If so I will look you up in the program list and visit.
