Titanium is expensive and very hard to work on.

If using titanium, there is a big difference from pure titanium (40,000 psi yield) vs aircraft grade titanium Ti-6Al-4V with 6% aluminum and 4% vanadium (120,000 psi yield).
...
And a Good grade of carbon pultrusion processed Rod, it will have an Ultimate tensile strength of 320,000-psi.
Ya GET it ?

Bille: with your knowledge and experience of carbon fiber, you are going to make a great product. Please share with us of your progress.
I almost lost my titanium wing yesterday,
The screws holding the wing almost fell off.
MHL is the only one I know of that mounts the front wing on top of the fuselage.
Most every manufacturer mount it from the bottom to reduce the stress on the screws.
That is a very bad design flaw.
