Subject: Re: 1/8" great size
Maybe you have a thicker wall 1/8th inch tube. I am glad to here of your luck with the 1/8th inch tubes. I will have to try again. I fly kites and I know that you can get CF tubes of the same size with different deflection rates. Mine was real floppy (lots of deflection) and did not work well at the standard Bug length. Do you know the manufacture of the tube you used? Also was it a Pultruded or CF Raped or straight CF?
