Wing tube weights?

[GW]

I replaced an aluminum wing tube with carbon from PAC.
Its a great fit. Tony Stillman told me at the Districts last year that if you get a loose fit when changing to carbon just apply some thin CA to the tube for buildup to make a nice fit

  While we're talking about tube weights,  does anyone have a comparison of wing tube weights carbon fiber vs. aluminum?  Also, what's the probability of a good/loose fit with existing cardboard socket.  Temptation comes with sockets pre-glued in wing panels.  Thanks,

        GW, those weights were the tube only.  The socket by itself weighs .3 ounces or 9 grams.  Considering how far back you are saving the weight, it will make a differance if you need to add nose weight to balance you plane, due to fact you will need a lot less nose weight than you would have with the heavier stab tube.

      many thanks Mike. 

      near 1/2 oz savings out of the tail . That might just make the difference I am looking for. 

      Is that just the tube, or including the socket?

            7/16x12 Carbon .4 ounces or 12 grams.

            7/16x12 Aluminum .8 ounces or 24 grams

          Anyone know the weight savings(or percentage of weight)  a carbon stab tube will have over the  aluminum stab tube of standard length (12" i think)?
