What can quantum tubing handle? I'm rebuilding a 3" Honest John and decided to try quantum tubing but it's a lot flimsier than I thought it would be. Debating on just eating the cost and ordering some LOC tubing. I flew my original rocket on H550's but I'm skeptical on the quantum tubing. Doesn't help that I also ordered a PML Mini BBX the other day that has quantum tubing.
