  2. Video is obviously more important - you don't want to cut some beutiful peaces just because the next block of the music is over, but on the other hand - normally you can't cut music so you have to deal with fitting your video (with all transitions and video effects) into the music. Cause normally - you take music "ready to eat" and video - is your arena :) where you have freedom for creativity.
    As for compressor - so far I've been useing Microsof Movie Maker (which comes with Windows XP and could be upgraded to v. 2 from MS website). It uses MS Windows Media Player 9 codecs and you can also download them from MS website so your friends can watch your work too. This is far not the best software, but on the other hand - simple and runs on my work notebook with no need for extra licence ;).

  3. Spent last month making my decision on camera and after all research (90% on this forum) just completed the deal on e-bay for TRV19.

    Well, now it's time to get ready to mount the toy. I jump regular Velocity helmet and they have Velocity Top Mount platform which I'm thinking to buy. Anybody used this equipment? Pros/Cons? Any other suggestions on Top Mounting it? (other manufacturers, other kinds of platforms?)

    Thanks in advance!

  5. Yes, there is a kind of irritation. I think this is because of the lack of endomorphin we get from jumps ;). I used to have really hard times during non jumping winter and I didn't have chance to go to other region where i could jump. But this winter I tried snowboard - wow! now winter makes sence, it's a lot of fun, thought can't fully substitute skydiving, still - a lot of performance, a lot of space to learn, to improve, to be on nature among good friends, btw many of skydivers do snowboard here so you are basically among you good old friends!
    Cheers, Spring is coming soon!

  6. Though Syn said to all of you guys "thank you", I want one more time thank to everyone taking part in this discussion! I can't think of any other community that would be so supportive and understanding to each other!

    My special respect to GravityGirl coz I'm a father of 3.5 year old daughter and can understand what she feels and I bet she knows perfectly what I feel or even better - what my wife feels - we both skydive (crazy parents:S).

    Thinking of the fear and price for the joy - many perfect descriptions were given here I have not much to add. One thing I'd like to stress on is always BE HONEST with yourself do you really want to do this because you want to do this or because you want to look cool or impress someone? After our daughter was born my wife didn't want to come back to sport at all - she was very much concerned about her mother's responsibility and I can't even think on blaming her for that, but when one year later she decided to come back... don't know why, but I had a feeling that she was not quite honest with herself and she wanted to return just to be on the same track with me.... I was very worried about her until I really saw that she enjoys the sport and would do it even if I don't. What I want to say here - don't ever let peer pressure affect your go-nogo decision. Not supportive, but as I said - for yourself - jumping in attempt of trying to be cool and brave - I think that jumping with such attitude would affect your ability to handle emergency or any unusual situation.

    You mentioned that all your fears are gone once you come to the dz - great, I think with the current situation as you describe it - you're on the right track - you really might be hitting the wall that nightjumps described and I hope you'll get over it, but if you keep coming to the dz and find your concerns are still with you, even more if for a long time, after say 10 suggested "all about yourself jumps" you feel that it's not yours that you shouldn't do it.... I'd probably suggest quitting... at least for some time, later on say in half a year you may want to come back and really have fun and joy, just keep in touch with your sky buddies!

    As for the choices and necessity - all depends on the way you want to put it - i.e. I could take a train to work (statistically they are safer than cars), but I take car cause it's more comfortable and so on, should I be concerned about safety in my every step this way? I think this is a misleading way of thinking. Absolutely different would be - if I had a bad (or very good ;) sleepless night and in the morning I doubt my ability to handle the car in emergency - I would take the train - this would be smart, but this is not about quitting the car driving to the safer trains for entire time.

    I prefer the thought that when it's your time - it's your time... For my current job I get to fly as a passenger in commercial airliners a lot and to be honest - that scares me a lot more than skydiving. I'm not sure about the number of accidents, but the number of people killed in airline accidents is extremely higher than that from skydiving. Do I have to change my job that gives me $$$ for life (and for the jumps of cause ;)??? to be on the safe side and have less/no air travel? I don't think it'll save me if my time comes. I had a friend who kept away from any risky activity and eventually died in car crash (this is not a dummy example, this is true)... I have another friend who (from my point of view) absolutely recklessly challenges the world in any possible way - skydiving, flying a hang glider, paraglider, scuba, climbing and many times ignoring safety... He got out of so many bad situations basically uninjured and still alive (thanks God!) I guess it's all about luck, destiny, father Lord or whatever you call it.

    You're right, skydiving is not one of the things we have to do, but for me and for my sweetheart - it is something we really have to do to really live the life, to really enjoy life, it's not just entertainment - it's part of our life and spiritually is far more important than our jobs careers or whatever. One thing that could really balance it - our child and our responsibility for her future, but for this reason - we never do anything stupid and apply all we can for the sake of safety - learn, practice, be always on guard for the shit to happen. At least “over there” I will know that I did everything to stay safe and with my beloved ones.

    Listen to yourself, make a decision and never regret, regardless of what decision you make! (and don’t be afraid to change your decision in the future if you decide something different – life goes on and variables and constants of it’s equation don’t stay the same, so the result can be different from time to time)

    Sorry if it’s too long…
    Blue Skies!

    mmm lets see, I found something in the Talk Back forum hmmm Accuracy Landing


    Shit... that looks scary >:([:/]...
    But you know what - they approached in brakes, leaving no room for flare and trying to hit the target, plus it looks like there's no wind - which in conjunction is quite bad for demo jumps on concrete.
    I don't know if anyone tested it, but if someone tried to put paraglider into the same glide slope at the same weather conditions, it will probably stall...
    But for better performance at low speed (we are not talking about more lift only), i think we have to get back to efficiency of the wing or L/D ratio, which if higher, would let it just fly better, but L/D ratio also is different at different AoA, so - if the rigger's angle of incidence is adequate to the AoA of the highest L/D ratio than the canopy would be less aggressive and more polite and fly flatter, actually it would be tuned to the flattest glide, but it won't speed up as fast.
    Yes, I think if you take two the same canopies, one would fly better at low speed whos AoI corresponds to lower speed flight AoA.
    Maybe here is anyone from manufacturers of the canopies or test pilots, who can confirm or disprove my thoughts?

  10. Agree and not :)Well, obviously, never seen accuracy canopy swoop, but that's just because of the huge drag they produce.
    If we think abstractly of an airfoil - at the same AoA and same airspeed more lift will be produced by the one wich is thicker - Bernouli's principle, that's for sure.
    What I'm thinking now is that the initial question was not only about the lift on it's own, but indeed, as you said about glide ratio. In this case reducing drag at the same angle of attack will result in the flatter glide slope. I think that one way to reach it - is to flatten a bit angle of incidence. In this case canopy will get a bit slower, but more efficient at lower speeds since could be flown in less or no brakes at that range vs the canopy with steeper AoI.
    To continue the discussion I need a board and a marker;)

    How about comparing it to gliding canopies, and they are totally nothing like accuracy canopies



    oops.... you're right, nothing... :S my guess would be that they are not that good slow flyers as accuracy canopies, but for slower flight capabilities thay have higher area and consequently - smaller wing loading.:)
    Paragliders are designed not for the slowest flight, but for the best ratio of Lift to
    Drag which is reffered as "wing quality" in Russian (who knows the correct term in English, please advise). This allowes them to sustaintain flight with very little vertical speed.

    Personally jumped accuracys as well as hps, but never flew paraglider, so this is just theory for me so far and I may be wrong.

    Who can add something here?

  13. Among the others:

    - Thickness of the airfoil - the thicker - the more lift at low speed.

    - Planform - the closer it's to the rectangle - again - the more lift at lower speed.

    - The design of the front edge - to maintain good presurization at slower speeds.

    IMHO the best slow flyers are Accuracy canopies. Compare even visibly details of the design of them with some hp ones and see the difference.

    The problem is that in most cases changes in design for increasing the lift at slower speed will induce more drag (like in the airplane - lowering the flaps requires more throttle, while having more lift at slower speed). So there always should be a balance.

    There's no mistake in my math. Doubling the speed, squares the forces. 10^2 = 100.



    Let me put my 5 kopeyek here :).
    Quade, you're 100% right about stick/toggle deflection. One can tell AoA on an airplane only if the wing is in stable level flight at constant certain airspeed. Otherwise - you can't determine AoA by stick deflection.

    Now as to the Math, I'm sorry, but doubling speed will not square the force - it will increase it 4 times (or squaring the increase rate of the AS). Aerodynamical force is directly proportional to square of speed so doubling the speed will increase the force 4 times, tripling the speed will increase the force 9 times.

    As to the main thread - downsizing will keep you sharp (or scared) for sure, but I personally disagry that downsizing can contribute to safety by any means...



    Unless I misunderstood his meaning he didn't say that it would contribute to safety. He did say that it would keep you sharp. I believe that they are not necessarily inclusive ideas.



    Actually what NCS whas saying that
    Quote

    bordom under canopy makes for poor decision making and the taking of un-nessesary risks.


    Which I uderstood as "downsizing to avoid bordom will protect you from poor decision making and taking un-nessesary risks and thus will contribute to safety":|
    Sorry if I got it wrong, English isn't my mom's tongue so please feel free to correct me :)

    Billvon's tasklist


    Thanks for the hand. I find this task list interesting and good reference before going down. One question - about accuracy - is it applicable to all wingloads? How do you do it on high loaded canopy?
    I used to do a lot of accuracy some years ago on large 7 cells, but smaller 9 cells don't fly with little airspeed. On my previous heatwave 150 loaded at 1.2 I tried and successfully did approach in half brakes for accuracy and it worked out pretty well with flare and soft landing. Didn't try it yet on my current Hw 135 at 1.37 and not sure if it's safe thing to do. The smaller you go the more airspeed you need. Or it's just a general rule - you can do it at full glide but you've gota get within 10 meters? Any thoughts on that? I appreciate accuracy a lot due to it's importance for off field landings and want to master it along with learning to swoop the wing at high priority.

    all the items of the legendary billvon's tasklist mastered.


    I'm quite new here, could anyone please drop me a link to the above mentioned tasklist? Thanks.
    ==================

    As to the main thread - downsizing will keep you sharp (or scared;)) for sure, but I personally disagry that downsizing can contribute to safety by any means... Not for me at least. Although NewClearSport was referring to

    The right amount of downsizing within the right amount of jumps

    And this may help one to keep good progression in learning and consistently have a room for improvement. The only question now is to define what is that right amount?

    Mr. Bill should be trying to climb up Sluggo so that he can eventually sit on the slider.


    Sorry Kris, didn't quite get it - sit on the slider - in front of Sluggo? or like on the neck?:|

    8 euros for 14000 ft?
    I'll be there next summer!!!
    You must tell me where and what plane they fly....
    Maybe we can hook up sometime next summer


    There two dzs around Kiev - one operates L-410 (up to 16 jumpers), another - An-28 (up to 22 jumpers with tailgate). Definitely, as I said we can hook-up and I will assist with all I can :), if you want more info - check out http://www.skydiveua.info/.

    And Labrys, pleased to meet you too :)

  24. Hi everybody!

    At a time when I registered at this site in 2001 I don't even remember if the intro forum existed, so I made a couple posts but never introduced myself:)
    Didn't spend that much time on boards before, but resently getting more jumps and more and more interest to different topics posted here.

    Started jumping back in 1992 at AirForce academy in Ukraine, but later had 5 years brake from the sport. In the meantime had flown for the AF of Ukraine L-39 and got lucky to get a military exchange training at Laughlin AFB, TX and flew T-37 and got in total a bit more than 300 flight hours on jets.

    As for skydiving - got back to sport soon after I quit AF searching for civilian career in 2001 and for today have 450+ jumps (not hell a lot, but I'm still young and passionate :)
    Skydiving is our family sport and we are jumping together with my wife (who I met long time ago at one dz :)it's our life or at least a major part of it. Enjoy formation skydiving and canopy flying - learning to swoop. Always information and experience-hungry will welcome any advise or comment from anyone, and while getting more experience personally may get involved in discussions myself grounding my own thoughts :)
    We live in Ukraine and if anyone ever would think of coming here - you are very welcom - will be happy to help as I can - think of it - jumps here are only $8 for 14000 ride ;).

    Well, that's about it, Blue Skies to all of you and... yes, Happy Thanksgiving :) Am I late? :| mmm, just one day ;)

  25. Thanks again guys. I respect your experience and your advise will help me to make the right choice. I wish we could meat at the dz somewhere someday.

    As for canopy control course - this is on my wishlist and next time when I can combine my vacation schedule with Canopy control course - I'll definitely take it.

    I only downsized from a 120 to a 107 after 1500 dives on the canopy


    Tonto, could you please advise, what was your wing loading on 120?

    As for a Safire at 1.4 - when I said "more forgiving" I meant only in comparison to stiletto or heatwave. I know that even Triathlon will be dangerous at 1.4 for unexperienced pilot.

    Thanks again,
    Blue Skies!
