12mm x 1mm x 1000mm wing tube Carbon Wing tube with outer sleeve

Ideal for the serious builder requiring superior structural strength in a wing spar. Ideal for models up to and over 3.5 meters (140 inches) wing span. The intended use these wing tubes is to handle very high G loads in excess of 250kg.

The carbon outer sleeve makes it easy to install and provides a rigid crush resistance by itself and the addition of the 2mm wall thickness inner spar combines to add the best possible structural strength at a very light weight.
