Quoted from MSLONEKER:angle of flipper bat??? I'm gonna have google that i didn't know that was adjustable.
The flipper shaft is held in place by a couple of screws/nuts down below, loosening those you can rotate the flipper a lot, the trick is getting them in the correct angle so they sit the same on both sides and flow from the inlanes correctly
Edit: but don't worry aboot any of that shit, get some real red or black rubber.
