Any tips, questions, ideas? Did I get any information/facts wrong? Let me know I can improve future videos.

Maybe put a plywood spar in the wings and if you want a speedster just shorten the wingspan and at a higher pitch lower diameter propeller

You could also increase flight weight by covering it in packing tape and or adding extra batteries just for weigh

Great effort. Breaking things is how we improve our projects. That was a good idea to put a folding prop on it so minimize breaking it on landing. For the same reason why not put the fuselage and servo horns above the wing as well? If it's going to be a belly lander, get the bottom flat by moving the fuse and servos above the wing. If you can't use a wing spar, use a vertical spacer over the centerline and wires out to the wings about 70% of the way out. Anchor the ends of the wire/20lb test nylon fishing line, doubled up teeth floss, etc. with some lite ply and an eyelet screw glued to the bottom of the wing. Some Nylon reinforced packing tape across the top of the wings to the fuse will help too. Overlap the tape over the fuse. I think flutter is going to be a problem with a long narrow wing unless it is made to be very stiff or is flown very slow. Using a symmetrical airfoil will help some though. After all that design is not meant to be a speedster. Just some ideas.

@@_BL4CKB1RD_ One more thing. Flying wings don't really need winglets. There mass contributes to flutter. Give it a try without the winglets. Good luck.

Welcome to KZread! IMO if a 100" wing fails with just a few additional ounces, the structure was marginal to begin with. A high-aspect-ratio wing can sustain severe g-loads without any spar, but you'd need a stressed skin that can withstand large bending moments (i.e.: balsa wood sheeting which is vacuum-epoxied to a dense foam core). Another option is a low aspect ratio (delta) which will reduce the bending moments but at the expense of efficiency. In your case a spar is indeed the easiest addition. Every choice you'll make will be a compromise in cost, reliability, complexity, and performance, which is what makes engineering so interesting. OTOH, early on I would suggest building on the experience of others before worrying too much about being an "engineer", that can come later. As for the video, I'll recommend that your intro avoid suggesting that the video isn't interesting, lol.

Thanks for the advice! I got inspired to make a channel from watching others. This was my first time making a flying wing. I tested out different construction methods and learned what worked and what didn’t. The added weight and the lack of a strong spar were not the only factors that led the wing to fold.

16:40 now you KNOW WHY a wing is SUPPOSED to have a load-bearing main spar, one that 'spans the width' of the fuselage; and structurally 'ties' the fuselage and wing halves together.!!

I already knew. I designed it to only carry the weight of itself. I made the mistake of attaching my phone to the plane. Still got good footage

What an awesome looking video!

You'll see in a lot of storebought planes that they add a carbon fibre spar or two across the fuselage and wing joints. This is mostly about strengthening the build. If you'd had a couple of spars, the wings folding up like that would have been a fair bit less likely.

I now realize since the that project why it’s better to over engineer than under engineer.

Это ценный опыт!

Nice effort for early build try, I like the high aspect ratio design. Looks a lot like full size flying wing built by the Horton brothers in 1930s., and very nice video. As others have said spar is critical. Ill add the the most stress is at the joint of the 2 wing halves join. The spar should go out at least halfway out the wing. It is tricky though with swept wing. Flight test good resource. Also look at Experimental Airlines videos. He has some with swept flying wing and shows spar stuff. Also he shows covering the foam board with packing tape before building wing. It really helps the strength even at the middle joint. Keep trying you are almost there!

Great job young man. This model flew very nice and with the affordability of foam board I hope you will be right back at it again soon. Flighttest offers free downloads of foamboard plans and tons of helpful build video's as well. I avoided flying wings for decades but once I built and flew one I'm hooked. I have several now and my biggest problem with them is keeping the orientation of the model in the air. Contrasting colors of cheap packing tape help strengthen and improve visibility. Good luck and have fun... keep your fingers away from those blades. ALWAYS

Thank you man for the tips! I have learned a lot from FliteTest and built some of their models. I wanted to see if I could build a plane of my own design. Mistakes are the greatest teacher.

Keep up the effort and your Chanel will definitely keep growing! My suggestion as a headphone user maybe not quite as loud on your sound effects. Im no expert. Just something I noticed.

Great design man! You're getting somewhere with it. I recommend a big spar (aluminium or wood or carbon of atleast 1000mm) to prevent wing collapse - I also would increase the winglets for better yaw. Look at my ''Grey Heron'' Flying Wing design - I have a Start-to-Finish build video on that as well: kzread.info/dash/bejne/eGl1zNOwh9TShc4.html that might help you with the process. Keep it up!

100 inches is fairly average for a R/C glider. Check what others are doing. Spars are essential as many have already commented. You had no structural integrity at all.
