Chain slapping into spokes, making a terible sound on fast descents

It seems like my chain is slapping my spokes (top run of chain) on descents when i am in the little ring in the front and one of my larger gears in the back. It makes a loud pinging sound. I can make the sound happen in the driveway by dropping the back wheel with the bike slightly off of 90 degrees. I can see the chain wiggling around and wacking the spokes.

Are there any adjustments I can make to quiet this?

Are you sure it is hitting the spokes? It is more likely to be chain slap. Is there a chainstay protector?

Shift into the middle or big ring when you top the hill/ascent. Then you won't have that problem on the descents.

Well, I made up a padded leather chainstay protector last night. Im quite pleased with how the project turned out:


I'll let you all know if it helps reduce the noise.
