Final Glide with World Champion | LS3 vs. Diana 2 Glider 

Thank you! Merry Christmas Tommy :-)

Thanks Tim. Merry Christmas to you and your Family 😊

There a also airfields/ gliding clubs which allow you to start at 13 and fly your first solo flight at 14. Just ask your local airfield, maybe you can start earlier.

@@Gega_Zautashvili. Yeah i considered that, but right now it is a money problem. I am waiting for my confirmation, so i hopefully can begin flying :)

@@antonwestergaard5211 good luck!

Stefan mentioned in the video it was SeeYou 😉. I agree, nice addition to visualise the race.

I agree. Condor must have a beta update I don’t know about for it to look so realistic.

Thank you!

What, the World Cup Slalom Skier?????

I´m using a Samsung S20 at the moment.

Thank you, wish you the same. 😊

Not very nice Christmas for GlideOmarama though. Hope ETNZ to nail it in March, all the best and enjoy it!

You don’t get as good rudder authority in a V-Tail plus you have two surfaces that are working perpendicular to each other to create a lateral force so that’s got to be less efficient. I have heard that they are more efficient in RC gliders but I think that’s just because you have less overall surface and less complication, fittings etc. All stuff that adds drag. So in a straight line a V-tail is probably more efficient. You do have your rudder pretty straight in a thermal but you pull quite a lot of elevator and a V-Tail would be less efficient doing that. Back to my earlier point about fittings etc, it’s a lot easier to create less relative drag in a full size aircraft so things don’t have to be simplified to the same degree to reduce drag. Horns, screws, mounts etc are all internal or easily made flush which you can’t do so easily with an RC model. In fact, I would debate if V-Tails are more efficient, it’s probably cheaper to have a more efficient V-Tail but with the right moulding and engineering I would expect a conventional tail or T tail to always be more efficient, at least when controls come into effect.

Yes, they are. And will be better in full scale too, epecially in straight flight. But there is problem when you will land in terrain. T-tail is more durable and more resistant angainst damage by grass, trees atc. V tail is lighter too for manufacturing.

Thanks Johan 👍 The phone is not an approved logger for the competition. Perhaps the Nano is a little bit more accurate, but to know the height and position which is recorded, is the key. When you don't fly competitions, the phone is enough. 👍

@@SteFly Thank you for your prompt reply, Stefan. 😀 I need a new phone and want to get into gliding, so this is very important information for me. Samsung Galaxy S20 is a bit too expensive for me so I’m looking at (older model) Samsung Galaxy S7.

At a competition the speed is also important ;)

@@SteFly sure! Speed is THE goal, I intended to reflect the fact that with the appropiate configuration for Xcsoar, and a bit of luck, arriving at 10/20 meters means you did achieve the very last challenge of the task. Nice video BTW, congrats!

Das würde mich auch sehr interessieren. 👍

Caz, I use the Samsung galaxy S20. It's ok but not great. Also It's getting really hot

50:1 is too optimistic. It is the marketing words. 46-47:1 may be actual.

And it depeds on the speed also. Sweet spot with max LD is around specific speed

An sich lohnt es sich meiner Ansicht nach (wenn nicht anders in den Regeln festgelegt), dass man erst zu tief ist und dann auf die Finish altitude raus zieht, oder?

@@glidingpassiongermany407 Im Condor Flugsimulator scheint mir das auch sehr Sinnvoll. In echt würde ich allerdings dabei eine gewisse Sicherheitszusatzhöhe verwenden. Es wäre doch schade, einen guten Wertungsflug zu verschenken, nur weil man nur weniger Höhe rausziehen konnte, als gedacht. Je nachdem, ob das PDA mit dem Logger verbunden ist, und wie gut die Höhenbestimmung funktioniert musst du mehr oder weniger Sicherheitshöhe mit einbeziehen. FLARM verwendet z.B. immer 1013,25 hPa für die Höhenbestimmung. Das bedeutet, die geloggerte Höhe kann stark von der Anzeige auf dem Höhenmesser abweichen!

Der Einflug in den Zielkreis ist bei Minute 12:30 zu sehen. Laut Regelwerk ist es nicht zulässig vor dem Zielkreis tiefer zu sein und dann nach oben zu ziehen. Das ist ultra gefährlich. In normalen FAI Wettbewerben habe ich noch nicht gesehen, dass das automatisch ausgewertet wird. Beim Grand Prix Wettbewerb gibt es eine sehr harte Regel die besagt, dass man ab dem Pflichtwendepunk nicht mehr unter die Höhe der Ziellinie kommen darf. Jeder Meter wird mit Strafsekunden bestraft.

@@pilot_Julius30 Auf welches QNH der Logger eingestellt ist, spielt keine große Rolle. Es wird eine Referenzhöhe aus der IGC Datei von vor dem Start ermittelt. Wichtig ist der Höhenunterschied zwischen dieser Referenzhöhe und der Zielkreishöhe.

Correct 🤙🏼

I don´t have any polars to compare both gliders. The max glide ratio of the LS3 is 41,8:1 and Diana 2 50:1 (source Wikipedia).

@@SteFly I see, so the other glider was gaining on you probably due to better performances, and not necessary better pilot skills.

@@leozerba Yes, especially that Kawa is serial winner. This is for sure not because of skills but rather luck 😜

MC Zero does only tell you in perfect conditions without thermals, that you will arrive. If you add safety alt, there is no compensation for the distance. So if you are 30 km far away from the target with MC0 and 200 m safety alt, most probably it won't work (only if you have a good energy line). If you are 5 km far away with safety alt of 200 m, most probably you will make it. If you use safety MC, this compensation will be done automatically. That's how I do it and it works good for me. The most important point is that you have experience with the settings you use 😉

@@SteFly I run my lx at zero and my kids at what ever mc I want to calculate safety. But the mc zero I use to speed up, slow down to maximize my speed to finish alt. Typically where I fly, colorado we come home when there's no energy in the air from 80 plus miles out. Zero mc nails it every time. If my arrival altitude is low I just slow up untill I gain it back. Ask kawa. Bet he does this. Also nice to see the LS3 chasing the Diana. My best flights of my life have been in a 3 and a 20 against big ventus fliers. Happy soaring. Come to colorado sometime. Most challenging flying in the world.

@@tztz1949 Bill, how do you gain on glide by slowing up from MC0 (unless you are flying with a strong tailwaind)? In his book SK says he wants to be get to MC 4kts for safety.

@@johngalloway156 . By either speeding up past best glide or slowing down to best glide you adjust your arrival height in real time at mc zero. If conditions change you see it immediately and can adjust your speed accordingly. I run one device at mc 0 and one at mc 2 or so for safety margin awareness. This way you optimize your speed for fastest possible arrival. This is best done in dead air when little or no energy is left in the sky to find unusual sink.

Hab eine BT gekauft ;)

Verständlich. Die 5C stand ca. 10 Jahre im Hänger bevor Uwe sie gekauft hat.

Seit 13 Jahren... so langsam werde ich alt 😂

@@SteFly ach Quatsch 🙈😂

Du durftest doch schon die Vorprämiere sehen ☺

Stefan Langer das sind wohl die exclusive insights 😌

Vielleicht sollte ich das mal mit Patreon probieren 🤔

Ist auch eine Überlegung wert. Ich hab keine Ahnung ob das jemand machen würde?

@@chad9331 Ich finde, Stefan Langer ist einer der besten Segelflugvertreter in den sozialen Medien kann dadurch viele Menschen auf unseren Sport aufmerksam machen und hat daher eine werbetreibende und nachwuchsbringende Rolle. Durch "Premiumvideos" für Kanalmitglieder/Patreonunterstützer würde diese Rolle eingeschränkt werden. Vielleicht wäre es sinnvoller, SteFly-Fanartikel auf deiner Webseite zu verkaufen. (z.B. SteFly Fliegerhüte und Basecaps)
