Prop extension for a Patrol Q/B

[DBeaulieu]

Another general question for the forum. Do I need to have a prop extension for my Patrol project, or can I get the nose bowl and constant speed prop setup without one? Just starting the process and I cannot figure this out right now. Help!

I think most people do not use an extension.

Installing a Hartzell Trailblazer (HC-C2YR-1NX/NG8301-3X1) with 14" spinner (C-2299-4P) does not need a prop extension.

The engine needs to be set up for constant speed, though. On a new YO-360-A1A this means removing the expansion plug.

(when drilling the hole you can use a lot of grease on the drill tip to prevent drill debris from falling into the engine)
