Hi all,
Anyone doing any of this DS thing.
Does anyone fancy a 'trip' to the 'dark side' of slope soaring.
Where are the good places.

Hi Brian,
Tried once a while ago... Not a fan of that sort of flying. But I saw some French guys doing it at a much higher level, and I have to admit that is impressive to watch ! Just the sound of the glider, it's mad ! No videos can be justice to that ! The downside, was a lot of broken fibreglass at the end of the session !
In Ireland, Mount Leinster would be a good place to start with !
On a westerly wind, going up 9 stones and fly the backside here...
Worth a try one of these days, out of curiosity :?:
-
Don't know of any good places close by.
I've done it a little by the coast at Blackwater. This is not a DS spot. The back of the cliff falls away ever so slightly. You can really see it working when you do a few circuits. Even get that nice DS swwwwish. I only do this with a foam wing as there is very little space and you are flying about 2 metres from the ground to get the best acceleration.
Would like to try it a bit more. Defiantly gets the heart rate going. Although at Blackwater it is as much the challenge of not hitting the ground.
May be possible at Mt leinster with a north or south wind. Tried it once or twice with no great luck but could do with a bit more research!
-
Same time ! :P
But I reckon 9 stones, on a East or West wind should do it... :?:
-
East, west ??? You are confusing me now!!
On the southside of Mt Leinster in a north wind or on the northside in a south or south-west. They would be the backsides
-
Hi all,
Apparently whats needed is steep up little no or flat or round top and steep back down.
Not for your vintage models Fred !!!!!
It's a must do for the future.
-
Yeah a good steep backside to the slope is what is needed. See the diagram below.
Here is a panaroma of Parker Mountain where Joe Wurts explored and mastered DSing while bringing it to the attention of the RC glider world. It was a know phenomenon before but, I don't think it had been used/explored in the RC world before Joe Wurts http://www.withinc.com/~wwang/Soaring/pkmtn2.htm

:P God no ! 2 turns, and they explode !
On a second tought, that can be quiet funny to watch ! :D :D
Alright, I'll find a map for Mt Leinster, but definitively some suitable/good DS point on top of nine stones ! I've walked all the way a while ago, must find the photos I took that day !
I'll get the wing and the destiny ready next time... If we are not too lazy to walk up the hill that day, we'll have a go !

Hi Guys,
Not to set too high a standard but the current speed record is 365 MPH FOR DS'ing.
From what I can see the guys with the radar guns miss the really fast passes very often.
I have to say there is some MAD stuff on utube.
I think I'll dig out the old phase 6 for this and see if I can learn how.
Fred a south west wind at the nine stones is probably the best up there, but we'll have to find out.
Brian
-
Yeah! I think you defiantly need something that can pull a few Gs. Things get fast very quickly if the site is working well I would imagine. Plus you need to be smooth. Next time I'm up there I will spend a bit of time trying it out!
I think my Luna can handle some light DSing.
There are a shitload of DS videos on youtube. They get boring fairly quickly but don't think that would be the case with a tranny in your hand (one for you there Keith :D)
356MPH might be a lot to ask. Apparently they need to have a special radar gun for this as the standard one is too slow. Maybe we should set a goal of 100MPH for ourselves??!!
-
Hi Joe,
I think I'd be happy if I got it to come back up that hill into wind :shock: :D
Brian
-
yeah there is that alright!! :lol: :lol:
-
I certain think the north/south slope (up the hill from the car park) of Mt Leinster could be the slope to do it. But I'm not sure. There certinaly is a lot of turbulance behind the slope in a strong wind. May be a light to moderate wind would be the best to test it.
-
Hi Alan,
Keith and I were up there yesterday and we had a look.
There are two rockey outcrops that have the effect of making the front and back slopes meet at a point,while the rest of the hill crest is rounded off.From what I have read these two places look good.
We will have to see.
Keith just for you ; www.stanford.edu/~mberry/Papers/Davies_290_DS_boslough.pdf

Hi all,
Anyone fancy a trip to Mt Leinster on Sunday.
Wind looks good for the south slope and the direction is good for a trip to the dark side. :evil:
Who has the liathroidi to take that first plunge. :shock: :D
Brian
-
Oh bad!
I'm away from IE! :(
If this happens, pleaseee someone take some videos! :)
And share.
-
Hi,
Sunday should be OK for me!
Will plan to get up there early to have a full flying day !
We'll keep an eye on the forecast :?:
-
The forecasts I'm looking at show west-south-west winds for Sunday. Don't think the south slope would work.
In addition I've been up there (South slope) twice this week and found a bit of a problem with that big nuclear bomb in the sky...... It's very low at this time of year. :cry: So if the wind is in the south I'll be giving it a miss.
If your going to D.S. you'd probably be okay, but for general flying, with the lift being a long way out on that slope, and with low sun it aint very comfortable........Trust me on this one! :wink:
If the wind veer's to the west I'll certainly be there. The top west slope is my FAVORITE :D (I love it to bits!)
BTW Fred, welcome back to the forum :clap: If Joe is still alive (I haven't heard from him for ages) he might turn up as well and I can give him his models. (Just in time for xmas.)
Nando is becoming a voyeur,.......he just likes to watch video's of others doing it! :wink:...........(Definitely a perv' that lad)

Hi Guys,
Keith may have a point, we will have to see later.
The forecast yesterday was for SSW wind with high cloud only at 50%.
Now its WSW wind but with a lot of low cloud.
Saturday's forecast will have to tell us, fingers crossed.
Brian
-
Thanks Keith :D :oops:
On holidays now, lots to catch up ! :!:
Well, if the forecast is WSW, why not having a drive and come to Kilakee ? :?:
Good training to fly in another slope (sorry Brian, no DS there!), and the Johnnie Fox is 5 minutes away ! (for a tea eh!) :D
-
Hey Keith!
I´m not the one making topics about Boobies! 8)
Either way i had here my FCamOne2 waiting for me, I'm going to make some videos and send them over!
Don't wanna be the only RC voyeur in here.
Sorry for the off-topic!
-
Are we are dropping the D.S. ( Dark Side, or Dymanic Soaring) what ever the meaning of the abreviation is. :?: If so I'm thinking Saturday would be the better day for flying. At least from the present weather reports.
I've never been to Kilakee, is it high? i.e likely to be cloud bound?
Nando, I assume these videos you're making are suitable for family viewing?
-
Hi all,
The DS mention was a 'challange for fun' based on wind forecast yesterday. This Keith I will only try if you are there to hold my hand. :lol:
But to go flying is the real aim, and Mt L west is starting to look possible.Lets see the forcast tomorrow evening,but Sunday suits me best.
Brian
-
How do I get to Killakee guys? I'd be going up the N11 :?
K.
-
Hi Keith,
At the moment all forecasts showing rain from west to east through Wicklow and north of that. We will just have to see later or tomorrow.
Brian
-
Alright lads, weather still rubbish over here in Kilakee...
But definitively clearing up !
What is looking like down there ?
Anyway, will certainly fly local today, we'll see for tomorrow...
-
Hi Fred,
The sky is on the ground here with just some breaks in the low cloud.
Forecast for tomorrow is now showing even more low cloud than today,almost 100% cover, not good.
We will have to see later but it's not very promising.
Brian
-
I haven't seen Mt. Lienster all day, it's been covered in cloud. Tomorrow looks like more of the same, and even if the cloud lifts I don't fancy flying on a south slope on the shortest day of the year. :(
So,....unless the wind veers west, (and it's forecast to back south) I won't be sloping tomorrow I'm afraid guys :cry:
I might get a different model out. It's got one of those funny, whirly things on the front of it.
Anyone up for a spot of power flying? :wink:
