eBay Carbon Fiber Tube Strength

Be VERY, VERY, VERY careful with what CF tubing you buy. Some of it is really pultruded fibreglass tubing with a cosmetic cover of carbon fibre. Such tubing spilts over the full length when bent a bit.

I do not know what this stuff is as they do not really say, but they DO mention the fibreglass, so I am suspicious. On the other hand, it is probably just fine for orthopters.

Cheers

Might be better off at looking for carbon fiber arrows on sale, clearance, etc. Used some of mine to make an external frame backpack.

Thanks for the heads up. I found another listing that's a little pricier, but specifies that it's roll, not pultruded, so I think I'm going to try that out. I'll report back here when it's gotten some use.
