  4. I'm trying to setup the Swoopware tandemvids software for our small DZ since we plan to streamline pretty much everything including the workload on the video guys.

    I really cant seem to get any acceptable results from the template i have spent quite a bit of time making. I thought maybe someone here would be kind enough to share their tandemvids/vegas template for inspiration and rough setup? I'm hoping that changing around in a premade template will remove alot of the timing and volume issues I'm having.

  7. Did a 5000 ft testjump for a small Danish production company that had designed a nice system for streaming from a gopro. It even worked on an AFF from 13000 ft. It did stutter a bit in the plane but after climbout it was perfect.

    It's kinda wierd to watch the jump live.. :)

    Unfortunately I'm not an electrical engineer so dont know the details, but I have pictures of the setup. From what I remember price were around EUR 4.000.

    The guy who designed it works in a company called CPH Live if anyone is interested.

  8. From my understandign its a danish container manufacturer that went out of business some years ago.. Still being jumped here in dk..

    Maybe contact Erik at www.paraservice.dk for more info on that specific container since I dont think any of the manuals and documents exists on the interweb.

    Aren't you still going forward through the air?

    If you could feel the wind at your back, the canopy would stall.



    Doh. Was thinking that if my groundspeed was lower than actual windspeed. But Im still going relative to the wind so I will always feel the wind against my face. And yes, I see that would stall the canopy..

    Let me ask this: Would it help a hot air balloon to deploy some sort of sail? Would this affect it's ground speed at all?



    Dont know actually. Wouldnt it move faster? My extremely limited knowledge about hot air balloons says that they cant steer and only move with the wind. Wouldnt a larger area then mean more speed? Or is the balloon always travelling at the same speed as the wind around it?

    -If you are upwind of the DZ (with the wind at your back), the idea becomes staying in the air as long as possible. The tailwind is helping to move you back to the DZ, so the longer you are airborne, the further the wind will push you.

    For this reason, deep brakes are typically the best option as they provide the lowest descent rate, and the longer it takes to get to the ground, the further the wind will push you. So get yourself turned toward the DZ, and get on the brakes ASAP to give yourself the best chance to make it home.

    -If you are downwind of the DZ (with the wind blowing in your face), now you have another problem. What you're trying to do now is penetrate as far into the wind as possible, so what you're looking for is higher airspeed, so the best option is generally full flight.

    To aid that, you can tuck your legs up by bending at the knee and getting your lower legs behind your upper leg, thus reducing drag. Keep your arms in tight to your body, and maybe even behind your body, again to reduce drag. All of these little steps will boost your forward speed by a couple %, and help get you that much further into the wind.



    To add to what Dave said - you should also make yourself small if you are upwind - it will still improve your glide ratio.



    Hypothetically, if windspeed is faster than canopy speed (so youre feeling the relative wind on your back). Wouldnt you want to make yourself big? I know that this is more rare than you going faster than the wind.

    I understand that i dont pick up speed like a boat by going a little angular to the wind. And 45 degrees might be overdoing it. But I think the idea is, that the wind "sees" a smaller area of the canopy by going at an angle. Therefore it pushes less. But yes, I do go sideways when doing it.

    It might not work. Therefore the question here. ;) But the advice came from the instructor at a canopy course where all of us on underloaded 240'rigs flew backwards.



    Number One, most important. I'm not ripping on you. This is a very common misconception. Probably second only to the 45 degree rule.
    And the only way you learn things is to ask these kinds of questions.

    The wind doesn't "see" anything. And it doesn't really "push" either.

    You are in the airmass. You are moving along with it. Your airspeed in the air is completely independent of your ground speed. You can compare a boat in a river current to get the idea. Any speed the boat goes by powering the boat (motor or oars) will be relative to the water, not the shore. The speed relative to the shore will be a combination of the waterspeed and the current speed.

    Think basic trig. If you have a headwind of 20 mph and a forward airspeed of 20 mph then your ground speed is zero. If you take a 45 degree angle, then your 20 mph forward airspeed is still there. But your groundspeed will be a function of the angles. Into the wind will now be 14 mph (or backwards 6) and sideways will be 14 (since it's perpendicular to the wind, it will be sideways 14).

    Did these same instructors warn you about making sharp turns while travelling downwind because the tailwind might make your canopy collapse?



    Yeah, I'm convinced. Gonna try to find a decent way to point it out to the instructor maybe or just ask him again.

    So im back to trying to be small with my arms and legs directly against the wind. Thx for the feedback..

    Havent heard about the no sharpies in downwind either.

  15. I've been taught, that in my big ass student canopy, when I give myself a bad spot and risk going backwards because of headwind, it's better to be at a 45 degree angle to the wind. The theory should be, that I present less canopy to the wind and by zigzagging with flat turns, I can cover more ground.

    I havent done it enough times to know if it's actually working yet. Any comments from the canopy gurus? Do i burn too much altitude on the turns?

    Frontriser on the student chute isnt really an option (im not heavy enough).

  16. Really great thread. Learning alot from it. Can see that i need to focus way more on safety.

    Did AFF in a different country where I almost (but not enterily) understood the language. Alot of times I was thinking that this sounded really important, but I didn't really understand it. Took me a whole day to get that a situation where the pilot is on the floor in the plane, can result in somebody ripping up the plane, because the instructor was talking about the PC and not the actual pilot. Doh!!

    #1 jump. at VOSS norway without radio. Was kinda oblivious to the whole canopy ride thing. Just wanted to jump out an airplane. Started landing pattern at about the double altitude that I was supposed to. Overshot like crazy. Saw powerlines and thought fuck. Turned 90 and landed uphill in complete sidewind. Luckily did PLC and it didnt hurt too bad.

    #30 About a month ago. Still student. In a hurry to get to plane. Got gear-checkout from instructor.
    While waiting in line to get on, the instructor comes running out from the clubhouse and checks my cypress, because he forgot that. It occurs to me that I didn't check it myself and it was the first lift of the day with that rental rig.
    Learned that I really need to check my own gear and not rely on everybody else.

    I love this sport, and I love that I'm completely responsible for my own safety (soon anyway). Here stupid things have consequenses. To quote my AFF instructor: "Remember! It's not complicated.. But it's important.."
