Received the Airborne and have started assembly. The Drive Side cup won't start though the threads look perfectly OK.
Are you screwing it in the right way? It is ISO left hand thread. The fact that it is a Ti BB shouldn't make it harder to screw in the cups unless the threads are munged. You'll need anti-seize with aluminum cups going into Ti.
I ordered English Power Torque cups. They came in and I never actually bothered to look at them. Yep, they're Italian and that's what the problem was. Ordered the correct parts. Again.

????? They, wherever you ordered from, SENT Italian threaded bottom bracket cups? That is a whacky error. Italian threaded bottom brackets are kind or rare now days. Very few bikes continue to use it. English threaded cups are on 99% of all bikes. So the typical, far more likely error is you order the rare unused Italian and receive the common used by everyone British cups in error. Not what happened to you.

Kind of like driving a Diesel vehicle and going to the gas station and pulling in wherever and putting fuel in your vehicle. But gasoline, the 99% used fuel, spigot is too big to fit into the diesel hole in the vehicle. You're looking for the rare Diesel/Italian and getting the common everywhere gasoline/British instead. Gas stations avoid this too easy to occur mistake by making sure gasoline spouts are too big to fit into Diesel holes.

The rarer hard to believe it ever happens scenario is the person driving a gasoline vehicle pulls into the station and puts Diesel into the vehicle. 5% or less of the people want Diesel to begin with. So not much chance of this wanting Italian but getting British error ever occurring. And filling stations don't size the pump nozzles to prevent this rare error. Painting the Diesel nozzles green is good enough.
