|  CS Props on a Single
Hi all - If oil pressure is lost on a single with a constant speed prop, it GENERALLY goes to a high RPM setting instead of a full-feather (like twins), correct? If so, is the spring/nitrogen chamber BEHIND the hub and the oil reservoir in front of it? Thanks! J. |

If you lose oil pressure in a single the resistance from the relative wind will force the prop into the low pitch/high RPM setting. The nitrogen/springs is only for multi-engines that need to overcome the relative wind and move the prop to the feather position.

Just to clarify, There still is a spring in a single engine C/S prop. It's is just like you said, backwards from the design of a multi.

I like this site for propeller information. http://www.mccauley.textron.com/pro-...pframeset.html Click on Tech Guide and then look under Propeller Operation for more links.
