These go in the center section spar. The tubes weight just shy of 6oz each, so I can add 6oz, 12oz, or 18oz to the plane.
From my experience in the Spring Fling in Sacramento, the plane can use the forward CG shift in the wind anyway, and the tube is already there.

I will test and report back.

Flew a 20 minute flight with two of the three stick of lead, so, 12oz on board last weekend.
Seemed to fly just fine like that. I think that I can safely recommend using the center section carbon tube for a built in ballast tube.
