After years of trashing wood props in rain, I am looking at the sensy or really taking the plunge with an MT electric... RR Johnny Johnson wrote: --> RV3-List message posted by: "Johnny Johnson" It's the legal 70 x 81 cut off 1" and repitched 2", the work was done per Sensenich guidelines by a prop shop in Boise, ID. 81" was not enough pitch, and the engine was 150 hp then. 69 x 83 seems about right for 160 hp. Thanks for pointing out about the perils--very real perils--of severely repitched Piper/Cessna/et al props... that is a no-no of the most extreme nature, it is true. I should have been more specific in the original post. Johnny Johnson -----Original Message----- From: owner-rv3-list-server@matronics.com [mailto:owner-rv3-list-server@matronics.com] On Behalf Of Fred Bauer Jr Subject: RV3-List: Sensenich propellors --> RV3-List message posted by: "Fred Bauer Jr" On a recent post [JJ] describing an RV3 with a 160 HP Lycoming we notice that the Sensenich propeller was a 69 dia X 83 pitch. We do not see where Sensenich and Van's offers that combination propeller, the RV3 propeller Van's recommends is the Sensenich 70 dia X 81 pitch. If the 69X83 Sensenich is a cut down 74DM propeller or another cut down version of the Sensenich BE CAREFUL !!!!!!!!!!!!! John Thorp, the T-18 designer, went through a very detailed and complete vibration analysis after several fatal accidents with his T-18 design which involved using the cut down propellers. His conclusion was that the cut down propellers will fail! NOT IF, THEY WILL FAIL I have never had a propeller fail on me so I may not know what I am talking about but I can read and I can understand what I have read. ---------------------------------
