This is an optional SAB Titanium Main Shaft suited for use with the Kraken 700 helicopter. A lighter weight version of the original shaft.

SAB Goblin Titanium Main Shaft
Did not have good luck with this mainshaft, I believe it's too soft and bends easily and the ends get stuck in the transmission and very difficult to remove. I would highly recommend sticking with the steel main shaft instead and run the titanium spindle with it.
