Thanks for the reply. I knew and wrote in the original message about the brakes, I think it is one of reasons why it got line twists (the other is no tension on static line during deployment). Did not notice the incorrect slider settings. Stamp has at least DOM corrected with sharpie to state DOM somewhere in 90s (haha!), but manufacturer is stated to be Para-Flite... Do you know about anyone producing counterfeit copies of Safety-Flyers? That would be a bit strange… Can this (not being a genuine thing) be the reason for end cells closing randomly during flight? I can make some pictures of stamp and canopy later today.
