Hi Bud:
Can you give, by any chance the order number of the Aircraft Spruce
"firewall material"? There are several choices. Do you perhaps mean the
Stainless Steel mat?

10. FIREWALL 2000 CERAMIC BLANKET
<http://www.aircraftspruce.com/catalog/appages/firewall2000.php>
This blanket is .250 inch thick, weighs only 9.5 oz/sq. ft. and is
flexible enough to cover compound curves. The heat side of the blanket
is covered with stainless steel, the other side is aluminum It is easy
to rivet or can be glued into position.

Frans,
I didn't see anyone post an answer so take it from a guy who has built
and flown a half dozen Tri=gears.
The hole gives you 100 square inches of air exit, greatly improving
cooling. Maintenance is a snap on the nose. Go to Aircraft Spruce and
use the fire wall material kit to completely fireproof the opening. I
use the firewall material and seal all the edges with stainless just to
dress it up.
As far as the speed penalty, if I can still get 140 kts with a 914 at
75% power at sea level with a tri-gear. I don't see a down side. I've
flown other tri-gears with the standard firewall and they all have
cooling issues and do not go any faster.
As for me...Leave the hole and run cooler.

I'm building a tri-gear, and cut out the bottom of the fuselage
for the nose gear per instructions. Apparently, the idea in the manual
is to leave it as is. What are the aerodynamic properties of this hole?
is it sucking air out of the well, or is it building pressure?
I just closed it, by installing a plate in the nose gear system.
If the nose gear activates the spring, the plate opens with it since it
is attached to the frame. Normally it just blocks off this hole.
Of course I hope that it will be beneficial. Has someone else
been closing this hole as well? If so, was it beneficial?
