17 pounds , I have the CF wing tube, and header with canister.

I flew it today with a 22a 3D BME laminated prop, TBM 22x8 , NX 22x8 they flew it OK, but not as good as the best the other day, the best today was NX 22x8. I'd give rpms, but I didn't write them down at the time and don't want to put bogus numbers up.
