Adds a little mass moment of inertia, but being located at the node, it's useless as a torsional damper.

How much did removing this effect your W&B? you can feel it in pitch, so it must have been quite heavy.

Landol
Put it up for sale, RV-7's with a Catto prop (such as me) use them to help move the CG forward to help with the baggage compartment limits with low fuel.
If you check the archives you will see WTB posts fairly frequently.

Mark is still flying
Just wanted to post to say Mark Landol is still around and flying. He is a member of our EAA UL98 chapter. He has been "retired" from supplying parts such as the Landoll ring, starters, alternators, etc. but he is still very much active in our chapter. I do not know exactly how old Mark is but I do believe he is around 85 now. He is a great guy and is a wealth of knowledge about airplanes.

The difference is slight. I do a lot of "maneuvering" so that's why I noticed it.
It's about 11 pounds plus the bolts.
