John one more question. What would be the stall speed if a 3300 Jabiru was
to be used. Approx give or take a few knots and I certainly would no hold
you to it.

I agree with most of Boud's comments, but on the flip side, Calbie Wood has
plans for a metal wing with wing tanks. Pretty straight forward, if metal is
your media. I am putting all of my fuel in the wing for safety purposes and
to free up space behind the dash. In order to keep the fuel system simple
I'd either put it all in the wings or all behind the dash. If you are going
to use a small engine there is no need for anymore span than the W10 has.

Ross -
If you would like to read my yarn about the building of my metal wing
Tailwind you can find it on my club web site. Go to... www.raa-tr.ca
Any questions, drop me a line.

>Well said Earl.
In the accident of Roy Adams The fire was caused by the
carburator breaking off of the crankcase of the O-200 on
impact and draining the fuel from the tank into the fire.
So if the tanks are in the wings, same same. only they are
exposed to more damage.

Well, my numbers say a little over 60mph at 1500lbs wt, but a more important number
is the speed at minimum sink rate which will be at about 80 mph.

I have a W-8 with a C-90 and am interested in installing a 0-320. I was told that
the W-8 wasn't designed for the 0-320 to be installed. Is there any out there
flying? If so what needs to be done? Any replies will be appreciated. Thanks,
