EPP DS und Hangflugmodell

[Artur Blömker]

Hallo!

Oft genug ist ein vorhandener Hang für teure CFK-Modelle nicht so gut geeignet (Beispiel Lanzarote) .... und daher suche ich (und vielleicht nicht nur ich) ein

EPP Modell mit gutem Durchzug und DS-Eignung!

Ich habe bisher einen Nitro EPP, fliegt gut, aber hat kaum DS-Eignung.

Wie ist es mit:

M 60
Frettchen
Weasel
Supertron

usw. usw. usw. ??????

Wer da Informationen und/oder Erfahrungen hat .... :):):)

Gruss Artur

Ich habe angefangen mit dem Bluto von NCFM... Klein fein und Schnell... ;)

Damals das perfekte Einsteiger Flugzeug aus EPP; 1,22m gut ballastierbar... Und haelt einiges aus.
Er ist immer noch Flugbereit, wenn er mal ein neuen Akku kriegt heheh...

Aber leider gibt's den Bluto nicht mehr, den Nachfolger mit 1,42m habe ich auch noch gehabt. Danach kam dann der M60. Der M60 braucht aber ein ordentliches Landefeld, Harm ein guter Freund von mir in Holland hat einen.

Gruss,

Bob

Hallo,
geht ein Orginal Zagi nicht im DS? Ich habe ja einen und am Hang bin ich heute auch, ich kann das ja mal ausprobieren, der Wind passt gut - ach ich mach einfach mal ein Video (Wenn Willi die Kamara halten kann zum Filmen). Meiner Meinung nach hat ein Zagi mit so um die 800g gute DS Eigenschaften. Oder ist ein Nitro EPP ein Zagi?

Herzlich willkommen hier bei uns!

Ja, der Nitro ist ein Zagi, schon der besseren Sorte. Aber für schnelleres DS eignen sich gepfeilte EPP´s nicht so gut, es sollte schon ein Brett sein.

Bitte schön vorsichtig fliegen, Kim ... insbesondere in der Schneise ... ;)

Gruss Artur

Hi,
achso, aber ein Brettnurflügel gibt es bestimmt bei EPP-Versand oder so zu kaufen. Schau dort mal hinein.

Ja, ich pass schon auf,erstmal muss ich Willi fragen, ob er das zulässt.

Guys, we are convinced the best EPP DS plane is the Reaper! Five of us guys have them here and they are fantastic. I had a Bluto type plank before, and it was fast, but it felt "vague". But the Reaper is incredibly better. It just WANTS to DS!!! When you get it in the circle it just wants to stay there!

This is the manufacturer, and you can buy direct from him:

The Reaper has an excellent spar system, which you can see on our photos of building. The main spar is comprised of 2 tapered golf club shafts, and they are joined in the centre with a machined aluminium piece. It's a great system - the spars are so thick that they provide a lot of twist (torsional) rigidity, and they're virtually unbreakable. None of us has ever managed to break our mainspars, but we regularly break the tail boom spar. (We use the original design with the long tail spar, to reduce yaw. The new version has a shorter tail but it would not be as good at stopping the tail waggle!)

The DS Extreme has 2 huge spars, and we think it's not necessary. It would probably be good if you were always flying in 50 knots of wind!

I put a thick carbon dragspar along my trailing edge which helps too.

*** I also have to seriously recommend the Windrider "Bat" as a great DS plane for bad conditions and rough places. It is so tough, being made of molded EPP, not cut EPP. In standard form it is not really adequate (for example, it has EPP elevons!) So we modify ours a bit to make them more rigid and lighter (like a "Superfreak Bat"). It's truly a great little plane, and not expensive. It is amazingly fast, very seriously - one has been up to 163mph in the US.

This is the manufacturer, where you can buy them:

Ooookay ....... :p .......... 50 knots ... we never get that wind, so I´ll hear what you say - and prefere the Reaper!

196 USD .. at about 128 Euro .... okay - if it is good?

Guys ..... who wants a Reaper?????????? ;)

hallo artur,

also ich selber habe keinen, aber der 'flash' vom friedl ist hier bei uns sehr beliebt und soll angeblich einer der schnellsten nuris sein...hörensagen.....
leider, aber ein zwei der piloten von denen ich es gehört habe traue ich ein verlässliches urteil zu....anycase cheap and cheerful :D

angeblich schon mit über 200kmh in australien gemessen worden..... und ihr könnt das bestimmt besser :cool:

Hallo Artur,

diese Seite habe ich per Zufall entdeckt, ein paar Erfahrungen mit
EPP im DS haben die Leute dort dokumentiert:

Der Election 54 scheint ganz brauchbar zu sein....
Evtl. hilft's Dir ja bei der Entscheidungsfindung :)

Wowings planes are made right near where I live, and the owner is a member of our club. I see a lot of the Wowings planes where I fly. I have had 2 Ducks and lots of my mates have Skuas. They all fly absolutely beautifully. But I don't think any of the Wowings planes are suitable for DSing. Not very tough, or stiff, or heavy. They're more for light frontside flying. The Reaper is the other way ... not so much fun on the front, but absolutely amazing DSer.

Lower on this page you will see a photo of our friend Ken with his new Reaper, only maidened a few days ago. http://windsock.proboards76.com/index.cgi?board=general&action=display&thread=1193572451&page=4

It's interesting because it has 4 servos, and uses crow brakes!!

hello vonza,

most probably you are right, with regard to the wowing version (which believe is the original), but the one build hear in switzerland, is using a different material.....it is a black epp, which is pretty smooth. also the trailingedges are build in plywood, aswell as the rudders. further they are equipped with 1 ballasttube.

i heared only good things abt friedl and am pretty sure, that if u tell him what you want the 'flash' for, that he will êven put a 2nd ballast tube in.
as to stiffness, it surely depends on how you build it.....a local pilot here is flying a flash , and it is his heavyduty wing.....and with his one ballast tube the flash is really fast and stiff (1,2 kg). he was using an 8mm carbon stick to strengthen the wing plus the 10mm alu tube for the ballast.
it is for sure the fastest epp wing that size i have ever seen.

i'd like to see it once flying together with a frettchen in direct competition, as i believe the flash is faster....due to the size and rotationspeed the frettchen though seems faster. the nice thing seems that the flash with 1.2 kg or more has a very nce retention of speed, and is pretty stable for an epp wing..this just my 2c....

sinze the flash is pretty cheap, i think it is really worth a try. one very nice feature is, that you can tell friedl what servos u will use, and he will cut very nice and tight housings for them into the material.

never mind just my thoughts.

Wow, Christophe, I did not know that there was a copy of the Wowings S-15 being made. It does sound good, I agree. The lighter S-15's over here fly very well. They are very fast and aerobatic but for DS I don't think they track the same nice way as the Reaper. Not as tough as a Bat. Nothing survives high speed crashes better than the Bat. But the Flash would be a much nicer frontside plane to fly than a Reaper or a Bat.

[Vonza]

The Flash sold by http://www.epp-flugmodelle.ch/ is advertised as being a copy that has been permitted by the original developer, Wowings.com.

I have contacted Peter Loftus, the owner of Wowings and unfortunately I have to tell you that neither he nor the original owner of Wowings has approved Friedl to make a copy. And they are not happy about it. They will be contacting him directly.

As some of you will be aware, Wowings models have a great reputation. They were developed by Kye McDonald over many years before being released for sale. Kye has a very good international reputation and has been at the forefront of the development of EPP slope soaring since the early days. He's provided an excellent service to the hobby and he still works part-time for Pete as a consultant. The designs are owned by Wowings and it's not fair to Pete and Kye if people rip off his designs. We Aussies are very proud of them!

The S-15, the 48" Skua, the Booby and the Duck use readily - available aerofoils which Friedl could easily use, but over a long period, Kye developed and improved these models with variations to improve their flight performance. Obviously these are all incorporated in the CAD programming to cut the wings, which would distinguish their flight performance from copies.

Nach Kontakten mir der Firma www.wowings.com (http://www.wowings.com/) , in Australien, habe ich nun das OK für den Nachbau der S-15 erhalten. Da ich aber den Namen nicht verwenden darf, erhält das Modell die Bezeichnung FLASH.



Ohh I hope that ´ll get clear .... :confused:

[femo66]

sorry, but i cant believe that friedl is copying them , selling them and even writing that it is under permission, which he doesnt have......sorry maid - hard to believe.....but nevertheless, am sure that there must be written exchange between wowings and friedl....

dont get me wrong, i have no interest in friedls business, nor is he a relative of mine or anything similar.

why would he right that the flash is a wowing design, if he would copy illegally ???

no really....

nevermind.....

heute war geiler wind :D

[Vonza]

Yes, I was surprised too that he would say that. But he definitely does not have permission to say that.
