I have a RV8A with an O-360 and fixed pitch Sensenich prop. I am considering changing to a constant speed prop, but I am concerned about the added weight on the nose of the plane. My plane is on the nose heavy side as it is, and I would not like to make it any more so. I am looking at the Whirlwind RV series. 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,

I have a RV8a with a IO-360 200hp which is a little heavier than your engine plus I have constant speed prop and have been flying it since 2002. 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

Craig,
Do you have your battery in the back?
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.

Battery is on the firewall. CG with me and no fuel is 79.47. I am hoping to do this with minimum changes such as having to move the battery.

Craig, I had an RV6A with a Hartzell Constant Speed. I believe it added 40 to 50lbs on the nose. That wasn't a problem for the 6A. Can't speak for the 8. The Hartzell is a great prop (supplied direct from factory by Van's). It performed perfectly for over 500 hrs and is still flying as before. (sold 6A last yr). If you are considering a Whirlwind check it out closely as I have a friend who owned an 8 and could never get his to work as expected. That doesn't mean it's not a good cons.spd. product. It means just what I said.
