  1. Looks interesting indeed.. It would be nice to test jump those things. IG @skydive_tuke
  2. I haven't done any changes to trim yet but last weekend I was able to put seven more jumps with this canopy. I also bought Flysight to analyse flying. There was almost no wind that day and I got quite nice data from Flysight. Here is one of the jumps with flysight data analysis: And bonus footage.. flare power! You can follow me on Instagram if u want ;) IG @skydive_tuke
  3. It was like that on my very early design, even before than 10,4sqft prototype. Hmm I don't get this. If I understand what you are meaning it is something about "rotating line"? Airfoil shape is rotated around line, which is parallel to bottom surface seams. Maybe that line should be more like to be parallel with flight path line? ...I don't know, I'm still thinking this front corner problem is in brake lines or in stabilizers. IG @skydive_tuke
  4. At first, thank you Lee for such a good analysis for my problem. Today I watched really carefully all the photos and videos I have, and I think you could be right on that thing. Maybe this problem is not a trim issue. I guess it could be brake like and/or stabilizer problem. Outer line of the cascaded brake lines could be couple of inches too short? It pulls the trailing corner quite a lot even on shallow brakes. And when that happend, stabilizer starts to make weird wobbling. When making harness turns, canopy flies really well without any issues. Harness turns: Opening the brakes: Also photo: outer-brakelines.jpg This line is align with bottom surface of the airfoil. These pictures are from final design of the canopy and these shows a lot of how I designed it. side.jpg
  5. This "wobbling" is showing quite clearly on this video: (opening on this jump was best one so far) IG @skydive_tuke
  6. I have now jumped 10 jumps with this canopy. Openings have been ok, but maybe a bit too fast for being perfect. I'm going to make bigger slider when I have time for that. Current slider is from Odyssey 100. There's lot of power on brakes and it is possible to pull brakes all the way down before stalling point. Front risers feels nice! Recovery arc seems to be a bit longer than on my 107 Stiletto, hoho. But I also find out some weird behaving. Front corners of the nose make small "wobbling" when giving small brake input (maybe on half brakes) but when adding more brake it will be gone. Also on full flight canopy flies well. I'm thinking maybe I should move "dividing point" of the A-lines little forward. On the attached picture there is current line setup on black, and my proposal for fixing this problem on blue. What do you think? IG @skydive_tuke
  7. Very cool! What are your plans? What are you going to do next? I'm going to jump more with the canopy. It's now in my rig. I also started to design new canopy as well. We will see some day is that new design going to be something real.. IG @skydive_tuke
  8. I used SolidWorks 2015 for making 3d model. It was great tool to make surface model and it also has tool to make 2D patterns from 3d curved surfaces. It could be a pain to learn to use it if you don't have 3d modeling experience already. Canopy shape is not the easiest model to start that learning process. But good thing is that you can find heaps of tutorial videos from youtube to SolidWorks. I've been working as a 3d modeling engineer last 8 years so it was piece of cake for me to model this kind of thing ;) IG @skydive_tuke
  9. Same jump, different angle. I think from this video it's easier to see how it is flying. Outside camera: IG @skydive_tuke
  10. One of the best feeling what I have experienced. Definitely. IG @skydive_tuke
  11. Jump: (sorry about crappy raw footage) Landing: I Can't tell how good was the feeling after that jump! IG @skydive_tuke
  12. Fuck yeah! Finally did the first jump. is coming. IG @skydive_tuke
  13. Thanks a lot for the comments pchapman! I'm normally jump from C206 and if I'm sitting next to the door (first jumper) I think it's ok to not have pin protection flap. But I will think about that later.. could it be possible to built one to that kind of three flap desing? For the DZO problem: my home DZ is not commercial and we don't have DZO. ..but I understand your point. Cutaway housings are not tacked at the moment but they will be tacked. That loop handle looks nice on your photo but it looks also a bit scary to me. I feel it could be easy to make unintentional cutaway with that loop but it is sure easy to pull when you need it. IG @skydive_tuke
  14. Ok, I made belly container from old reserve container and it looks good to me. Whole setup feels quite messy when it's on my back with main rig, but I think that's the way it should be? I made attachment straps for belly container from old reserve risers. Webbings are sewn into container and there is velcro for attaching "risers" to hip rings. I also made boc pouch for pilot chute. How does that looks for you folks? Is there something I definitely should change? And one more thing, I borrowed slider from Skylark Odyssey 100 and it fits fine. It is just narrow enough comparing to center cell width. I think I'm going to test jump with that slider. I haven't done any plan yet for first jump. It's still quite cold outside and skydive season is not started yet. Some pics... IG @skydive_tuke
  15. Two more pictures for you. IG @skydive_tuke
  16. Not so much has happend here after last post but today I had time for short ground testing. Some photos attached. I'm pretty happy how it looks and works. pchapman and RiggerLee, thanks guys. I have to think once again how I'm going to attach third canopy to myself (safely). I still have reserve container with flaps from that harness and maybe it is possible to use it at the front with main canopy d-bag? I knot that shape of the reserve container is not perfect for main dbag but it should work if I add pocket for pilot chute? IG @skydive_tuke
  17. I have to chech that is some of those bartacks above upper stitching line, and if so, how much above. I tried to sew them between stitching... but I'll check. I'm not sure how I will jump it. Maybe I can use separate harness under my rig? I already have that kind of harness. It's made from old Wings rig, I just removed container and moved cutaway handle to chest strap because it's nice to have that handle in different location than "real" cutaway handle. But how should I pack the canopy? D-bag with pilot chute pocket at the front attached to some kind of velcro strap between hiprings? ..and deployment when back-flying? IG @skydive_tuke
  18. Thanks for the comment. Do you mean about the lower non loaded stitch line or loaded stitch line? And it could be failure point for stitching or what? There is also reinforcement tapes (about 6" long) inside those seams on line attachment points. IG @skydive_tuke
  19. Yesterday I finalized the lineset. Line attachment points are also done. I made all those "bartacks" with that same sewing machine and I'm not 100% happy with all of those, but I hope those are good enough. Here's some pics of the final phase. ..slider is still on the design table. IG @skydive_tuke
  20. Here is some new photos from yesterday. Next thing to do is line attachment points. The project has progressed a bit slowly but I'm already happy what I have already done. IG @skydive_tuke
  21. That makes sense to me. I just designed same size seam allowances to all pieces of fabric. Of course smaller to front edges on the nose. I have already leaned a lot of small things I could do better or wiser to next design. This thing about seam allowances is one of those things. Maybe I can do trimming after sewing but I still have to leave some exposed edges because I have already done half of those seams. I left too much seam allowance to those parts, but I think it's also fine like that. It only looks ugly with exposed raw edges? IG @skydive_tuke
  22. Sorry, I attached wrong picture of the seam. This is correct one. (I deleted that wrong picture from my last post.) IG @skydive_tuke
  23. No.. I mean seams in loaded ribs. I have already done those as I showed. I have seen those kind of seams in Skylarks canopies. But I also wanted to learn how to do "old style" seams. I didn't want to choose easiest way :D Really? I didn't know that. But, if I'm going to make more canopies, I'm considering to do more simpler seams I guess? IG @skydive_tuke
  24. Some more pics.. I copied the basic stucture of the seams from my good old stiletto. It was little hard to sew those top seams All of the top seams are now done and maybe 4 of the lower seams still under construction. IG @skydive_tuke
