I'd suggest going back to the seller, with a cold six pack, and thanking them for not including the battens.
They saved you from the temptation of actually attempting to fly that thing. Probably saved your life
40 years ago hang gliding started much this way, with people getting their hands on a glider, or even making their own, and learning to fly through the school of hard knocks. Some of those early pioneers are still flying today, and a few are here on this forum. Sadly, though, many many more were scared out, hurt, or killed. To this day the sport of hang gliding hasn't been able to shirk it's "dangerous" reputation. Which is not to say it isn't dangerous... it is... but it's not nearly what the general populous thinks it is.
So, welcome to the addiction, and I'm very sorry your glider purchase didn't work out. It makes for a neat shade awning, or sometimes you might find a restaurant with high ceilings like would like to hang it as tchotchke decor. Or the aluminum tubing can be useful for flag poles, or constructing anything where relatively light weight (aluminum vs steel or iron or whatever) tubing might be nice.
Lastly- since you are obviously interested in hang gliding- I'd encourage you to seek out a local instructor and take an intro lesson. There's no obligation to continue with that instructor if you don't feel good chemistry... so don't feel like picking someone and taking ONE lesson is any sort of commitment to anything but getting a taste of what we're all about... and you're obviously thirsty
Flying is truly amazing, and hang gliding is one of- if not THE- purest forms you will find. It's a natural connection of man (or woman) and wing, steering purely by moving our bodies. It is bird like. And there's no better time to get started, because training equipment makes learning easier and safer than ever before, and glider performance and forgiveness is better than it's ever been. Harnesses are more comfortable than ever before. And instructors have been continually "getting their act together" for years, with most approaching the craft of teaching with the respect and professionalism that FLIGHT INSTRUCTION deserves. So again, WELCOME! and let's meet up in the sky!
Cheers,
Ryan
Shut up and fly.
