Hi
I am looking for a wing tube for my SM big Hawk. I have received 2 from SM, but they just don't get the point. The first tube is a dural one and it looks sturdy, but it is short in lenght. The second tube is a carbon one, but because it could brake, they have filled it with resin and now weights 300gr.[

].
Does any one know a good source for reinforced dural tubes? I need one with 38mm OD.
Regards
Nuno
