After reviewing all the performance data on the various CS props available, I selected the Hartzell blended airfoil. I have an IO-360, 180 hp engine so the engine weigh is the same as yours. Looking back over my W&B data, I can tell you the Hartzell was 13 pounds heavier than the Sensenich. I have two Odyssey 625 batteries mounted just aft of the firewall. I considered moving one of them to the aft mount location but decided to wait until after flying to see if it I had a nose heavy problem or not. Bottom line, I did not see much difference so I left the batteries where they are. As I did with the Sensenich, I put a 25 pound shot bag in the baggage compartment if I'm solo and no baggage. My W&B does not require this, but I find it helps. I can tell you the performance difference between the Sensenich and the Hartzell was far more dramatic than I anticipated. You will love the change. I have a couple of hotrod Lancairs at the airpark and while they eventually pass me, I give them a surprising run for their money. BTW - I'm using the PCU-5000 governor and am very pleased with it. If you need a governor control cable bracket let me know - I have a new one sitting here I bought from Van's by mistake for the RV-10.

I have an IO-360 200 Hp / Hartzell BA CS prop (great combination) and have no issues flying solo with full fuel or near empty and no weight in the back. One note I have dual G3X and back up EFIS so I suspect my panel is lighter than a 10 year old build with steam gauges.

That being said I do keep 25 lb. of lead shot in the aft baggage compartment and a few tools which keeps the elevator pretty even or level in flight thus creating less drag. When landing it also helps with a lot less trim. I have confess my best landing are when I have a passenger in the rear seat and nothing in the aft baggage area Dane Sheahen RV8a On Jun 25, 2011, at 9:01 AM, Craig Gallenbach wrote: I have a RV8A with an O-360 and fixed pitch Sensenich prop.

Does anyone out there know how the installed weight of a Whirlwind prop compares to the fixed pitch Sensenich? The Whirlwind prop and spinner weigh in at about 38# according to the folks at Whirlwind. I was hoping to find out the weight of the Sensenich installation without pulling my prop.

Thanks, Matt. That is another one of my dreams. When I was a teenager, there was a doctor building a boat about the same size as this one of his own design which he had in the water at Bellingham, the local port. I remember thinking that he was an old man and would never get to enjoy it. I think I am probably older now than he was then, and I do understand finally what he meant when he told me he would enjoy it even if he never lived to see it finished. He too was a medical doctor, I think his name was Montour, but that was over 50 years ago now.
