And they use metal fasteners to attach the CF gussets to the CF tubes. Hmmm.

I've always found the strength to weight ratio of carbon fiber to be very interesting.
But I'm going to show my ignorance of knowledge towards the material at this point.
I have always thought that carbon fiber was a poor material to use in a tube & gusset design due to it "fracturing" when drilled.
Excuse my poor terminology.

Have you checked their prices? Hold on to your hat...

Kevin you can drill it just fine with the proper bit, no problem

Carbon Cub?

Carbon Cub just has carbon panels like floors and wing tips. Structure is still Cub Cub.

I wonder why the Holy Grail of tube fuselages is hanging on a wall in a museum?
I suspect it's unairworthy.
I would sure like 2 see the reinforcement schedule

Loudenslager designed that airplane for himself. Only he was going to be good enough to do the crazy stuff it was going to be capable of for his airshow. I doubt there are ten people in the world that could fly it as intended. Maybe 5. That is why its a wall hanging. His staple airplane is in the Udvar Hazy. If he had not gotten smacked by a truck on his motorcycle, it would have been the bar, and airshows would either be way crazier or ban.

Because it is not the holy grail of tube fuselages.
I suspect it's unairworthy.
That is a reasonable suspicion. The project was abandoned before first flight, circa 1997.

I suspect that there were some comprehensive engineering assessments of the structure.

What do you mean by "reinforcement schedule"?

The ply schedule

Anyone here who remembers seeing Loudenslager's airshow act in the Stevens Akro, can guarantee you that anything he designed (or had designed) to top that act would have to be pretty frickin' strong and durable !
