The electric motor just goes in or out. It does not care which way the blades are turning. Same as the adjustable screw. I am lucky in that this is an early 912. I understand that if this were a later 912 the prop hub would not fit. The plane is still a long ways from flying as I am doing a rebuild but getting stuff ready including switching from a 582 to the 912. Thus the new prop but want to use the inflight adjustable when ready.
