Designed for a removable turbine & "more accurate" exhaust tip. This one doesn't allow for a hand crank, but instead has you using your fingers to spin the turbine.
The base was redesigned so the model will rest against some stop ends and doesn't require it to be glued down.
Now you can pick up your turbine, spin it, and then place it back onto its base when you're done.
I also have the extra Stators and new Cowling from: http://www.thingiverse.com/thing:476563
