I need to source CF tube spars for an ultralight(ish) Volksplane style stab and rudder and I'm running into information overload on the different types of tubing (roll wrapped twill, roll wrapped uni, braided, etc.). Reading the descriptions on the interweb they all say "ideal where bending and torsional strength is required". Obviously there's a best choice, especially considering all the considerations I haven't considered yet (glueability, machineability, shock resistance, etc.) The tubes will have fairly concentrated bending loads and distributed torsion loads. If anyone has actual knowledge of this stuff I'd welcome your 2 cents.
