The latest PE Series II has a different frame for the new motor. The Kingslet Hall set has the same little motor as the Hogwart's. I am wondering if I could retrofit the PE Series II motor to the Hogwarts...
Hogwarts on the left, PE Series II on the right. The worm does look similar, just have to see if they're really the same. Then It's time for Mr. Dremel to make it fit!
