I am from pakistan. Now to learn from instructor and then buy a hang glider is impossible for me due to financial problem.Actually I want to build my own hang glider whose performance may be best and be safe also. Now the only mean to build my own is google, youtube and this forum.I have steel tubes instead of almunium,whose weight will not be much greater than almunium tubes as I think.It will be appreciated if you would give me the exact weight of 6 meter lenghty tube
A new, complete HG, in the correct size for you, would weigh 20,4 kg. Your longest tube would be 5m or less, and the sail would weigh about 2 kg. Steel cables (aircraft-grade stainless steel, not galvanized) will be a significant part of the total weight.
Your path is very dangerous, though. A friend of mine once managed to break both leading edges on his hang glider, avoiding spectators who drove a small truck into the tiny landing field and then stopped. I do not blame the pilot; he prevented any injuries to the spectators, but at his expense. He was lucky to avoid serious injury to himself, then.
His tubes were .049 inch (1.2446 mm) wall thickness, 6061T6 aircraft aluminum. He could not find the correct (.049 inch wall thickness) tubing anywhere. He bought the same size aircraft tubing, but it was .058 inch (1,4732 mm) wall thickness. The glider would be stronger, he believed. It was stronger, of course, but those tubes really needed to flex slightly, to turn (steer) the glider in the sky. He intended to test his repaired glider on a mountain. He had flown that same glider for years, and he knew it very well. What could go wrong? We had to yell and scream at him, but we finally convinced him to test the glider on a small hill, first. So, he tested his repaired glider on a small hill, and discovered that the glider would not turn now, to either side. The new leading edge tubes were TOO strong. He put the glider away; he had no more money for further repairs, then. The glider appeared to be perfect, but now it was completely unsafe.
Friends donated money, and we bought him the new tubes that he needed, from the manufacturer. The price was high, but we set the value of our friend above the money. With the glider now repaired properly, he was able to fly it again, just like new. It would have been a personal disaster to him, if he had tested his first repairs on a mountain.
Air does not accept excuses, not even "I did not know about that." We want you to succeed, here.
Please be careful. One part of my web page (linked below) talks about home-building your own glider.
