Ok, ok, I can hear Joe from here... "Not again!!!" :P :P
Well, yes, again, and again, and again !! \:D/ \:D/ \:D/
The problem with Retroplane, well, after the morning headaches, is that you always leave with a bunch of projects you always wish you've never agreed to (well, almost...)
I now have 3 new gliders that I need to find (big) space for in the garage !
First one, is a 1/4 scale ASH25 Fuselage, a bit of work this winter to have the wings done (by the way, that's 7mtrs of wings...) and a 4mtrs ASW15, my new sunday flyer :D
And finally, on Staurday morning, I left with this...

The white one... :P Just one number... 12 Kgs Soon to be at the slope for the maiden voyage !
Just don't tell the wife, as far as she is concerned, I had all this in a box in the garage for a long time, and finally decided to get them ready... :P :D
I'll keep you posted with the progresses...
And you, what's new in the workshop ? :?:
-
Jesus I would sell my mother for one of those. =P~
Nice one fred.
D.

12 kilos, that's outragous! Who's gonna launch it for you? No good asking Joe, the plane weighs more than he does :lol:
Oh, and something else you have to do Fred,......finish designing that 2.5mtr F3b, or what ever type it is. And if you don't finish it soon,..... I tell your wife the truth about these new 'projects' that you've just acquired :wink: Ha!
As for what's new in my workshop. Another Phase 6. My 'old' one finaly became so pached up with repairs that it was more repairs than original plane. And then the other day the ground jumped up and grabbed it as it was doing a loop.
So now that I know how to land these acrobatic darlings in one piece, I must get me another one,...........there're such FUN :D
Oh, I'm getting a new Tx as well, I've out grown the old one. I need some more mixes and proportional crow ability as well :D It also has a snap roll facility. Never seen a glider do a snap roll before! (well, there's a first time for everything aint there?)
K.
-
Very good Keith !
Phase 6 is definitively good fun at the slope ! :clap:
Hmmm.. thinking of it, I think I may missed a few infos for you for the flaps etc etc...I give you all that a bit later (have to do work from time to time... :P )
Dave, your mother do good cakes ? :?: :P
Everything can be negociated with good cakes ! :D
-
I'm saying nothing :roll: :roll: :roll: :roll:
Will there be a clear out Fred to make room for the new machines??
Any nice gliders goin cheap???
Crazy Frenchies!
-
:lol:
Are we still friends ? :cry:
Yeah, need to make some room !
For the first time ever, I might sale a few machines !
Thinking of the 1/3 scale Lo100 and my asw22... :?:
-
Well, for sure the Asw22 will go !
Kind of like my big fat Lo100... :oops:
-
And MORE BEERS !! :lol:
-
Filppen Hell :shock: :shock: :shock: . A 1/4 Scale ASH 25. That will be massive. You'll will probably need a glider trailer to transport that Fred.
The only projects I have going at the moment as you know is the K8. But when thats finished I have to repair the Pilatus and my Ruby. Then I need to fix that flippen hand launch glider with the crazy electrics.
After that I don't know what I'm going to build. I have a plan at home for a 1/5 scale Standard Cirrus (3m wingspan). I might build that. The plan is from the same guy that Peter is building his Pilatus from. Mike Trew I think his name is. It will be made all out of wood.
-
Fred, my mother is a bun master...black belt in bun making :lol:
I could trade buns for gliders.... I am all for the barter system :)

:lol: :lol:
One more...
Photo of the Asw15...
Just need to do the covering and put the servos in...
Need a bigger house and car now !

Photos of the Ash25 as soon as I manage to trade the fuselage back from Joe ! (might need bun advice here Dave! :lol: )
-
I'll give you a fuse for a 7 metre ASH 25, a 1:3 Ka3, a Sebart Shark and a skua for that ASW15!!! :)
-
You are not a good friend !
:P
-
Oh and I forgot I'll throw in a semi finished 1:4 scale Grunau Baby too.
And you say I'm not a good friend!! :wink: :wink:
-
Just to prove I haven't been idle. Here's a picture of my discus launch model. (I know it's not slope, but there's no thermal/flat field section.........Yet!). All scratch build apart from the boom. Vac bagged, foam wing with carbon tow spars. Elevator & fin built same way with live hinges. Fuz (such as there is) is a lost foam effort, although my next may be my first foray in to moulding.
Design is basically the Supergee from Charles River site by Mark Drela, but without flaps and ailerons.

Getting there with the ASW15...
Just have to put the servos on he wings, and hide the servos on the canopy, and ready to go !
Hopefully ready for this week end meeting for the maiden flight :D

Well done Fred, what other maidens will you be bringing with you? :lol:
Sunday's looking like a gentle 20Km/h against the north slope, and with some sunshine we may even catch a couple of passing thermals.
Looking forward to a nice easy days flying :D
K.

Thanks Keith :D
Here are a few more...

(http://www.gliderireland.net/forum/images/uploads/Fred/DSCF8063.jpg)
I hope to have it finished tomorrow... But not too sure about that, I don't want to rush it...
Still have the 4 servos to glue / setup in the wings... Hopefully, that will be done tonight, ready for setup tomorrow...
Another maiden, might be the Crystal... But we'll see.. I might bring it to setup, but I would like loads of lift for the first flight.. After, we'll see, but 12Kgs, that need a little bit of planning, well, just a bit more :P [-o<
Just have to ask Benoit to confirm the CofG to me to be sure now...
And the Crystal with the ASW...

Almost 10mtrs of glider in this photo :D
-
Hi Fred
Rachel was out for shopping during you made the photos :?: yes that's it, tell me that I am right :lol:
Stephan
-
:lol: No, not even !
That was my 10 minutes of freedom after work, before changing the baby, and put the girls to bed...
Negociation is everything :P :D
-
Corr, what a lot you got!
Don’t rush it Fred. I’ve rushed the finish on my Phase……………..and it shows! :cry: :oops:
It wont be seen when the plane is in the sky, but when it’s on the ground it doesn‘t look any where near as good as my first one……………
Ah well, I’ll remember to take my time in future. :roll:
Don’t think there is going to be “loads of lift” this weekend. It might be better to leave the Crystal until another occasion. (Save loading it all into you car)

They look like some sweet machines Fred :D :D . Love to see them fly, but I will be in Nice from Friday for two weeks. Do you know of any good model glider clubs from around there.
-
Hey Fred,
those are beautifull gliders. :clap:
The modern soarer are not my cup of tea, but they have a special sort of elegance.
All the best for the maiden flights [-o<
Regards
Lothar
-
Thank you all :oops:
Ah well, now, the most important thing is to put them in the air ! Whatever happen !
For the ASW15, only managed to glue 2 servos tonight... Not sure now it's going to be ready for this week end... Next one for sure... We'll see tomorrow...
-
And finally, a photo of the ASH25, my modern glider winter project !
I'll post on the forum the building process, might be interresting for some !
Note the big smily face ... :lol:

Don't know if I mentionned it already, but fuselage is from Gewalt
Profile will be an evolution of Eppler 68, E67 and E66 (very close to the HQ3.5/xx.. Sound good for thermalling and slope)
I will not go for a full house wing (flaps etc etc..) just ailerons and airbrakes, but that might change later !
-
Well, that looks pretty impressive! :clap: The plane I mean, not Fred. (Although Fred can be impressive he’s certainly not very pretty………………..but this is very off topic.)
Let’s see how you did it Fred, …..probably all in one night knowing you! :D
I’d have thought you would have preferred flaps rather than airbrakes. If the lift is light a few degrees of flap could help you get it up. (Er, :oops: :oops: :oops: :lol: ……..oh, never mind)
So when will we be seeing this beast in the air?
K.
p.s. Your lawn needs cutting,……..the shrubs could do with some pruning as well. .........What does Rachel do with her time anyway!

Perhaps she beats up cheeky penguins?
-
It's a good look Fred. Not quite sure what it's saying. Maybe "Oh bollox now I have to build this thing!" Or "now look what I got myself into!"
I should say nothing as I will have to cut the wings for the beast :? :?
-
:lol:
Yeah, more thinking "Joe, where are fecking finished set of wings !" :lol: :P
I'll pass on the messages to Rachel.. She will deal with you later ! :P :P
But sound like my next week end job alright... :!:
Keith, for big wingspan gliders, I found that Airbrakes are much more precise and generate less unwanted effects.
Also, all profiles are not good with flaps, sometimes adding flaps can generate more problems than anything else !
I keep the wing clean and simple this time :D

Oh, that's interesting Fred, I wasn't aware of that fact. I'd assumed that flaps would improve the lift of any wing.:?:
Thanks
K.

Well, yes, and no :P
Flaps will improve the lift Coef of any wings, up to a certain point, then, generate more drag.
Same flaps up will increase the speed up to a certain point (you are destroying lift (?) ) good for transition for exemple, to get to one thermal to another.
So, flaps are good as they will increase your range of application, but you have to be carefull ! All profiles are not designed to have flaps.. You can add them, but the result might be worse than the remedy !
Some profiles are specifically made to have flaps, like some TP/SB for recent ones or Wortmann are made specifically to have flaps.
For a Wortmann for exemple, a serie FX xx xxxK /10 mean that the profile can have flaps (letter K), followed by the size of the flap ( size is 10% of the chord here)
And also pure lazyness ! Easier to build a wing without flaps ! :lol: :P
But maybe someone will have a better explanation! Based on experience, like for the Algebra, I put 1mm of flap (barely see it moving down!) and the thing keep going up, more, and that's it, the thing won't fly, just brake !
-
Have made a few decisions on this winters projects, so in no particular order:
KA-3 from Island model's Short Kit
Fafnir - from Vince Cockett Plan
SU25 Frogfoot PSS
Jart
and I still have a Bubble Dancer thermal model to finish!
Made a start yesterday, by making a foam plug for the Jart fuz and this will be made using the lost foam method.
-
Well,
I don't know, if I am right in this area here, it's a Motorglider, but some of You may remember the little wooden triangle I flew in Ireland at Joe's Cliff, Mount Leinster and on the airfield (where I met this funny britsh man named Keith). This was Horten XII.
I scaled it a little bit over the last few weeks.
See the result:
(http://www.gliderireland.net/forum/images/uploads/lothar4862/27092009%20002.jpg)
The weight is about 7 kg, Span 3,2 m. It's flying very nice and much slower than the small 2 m version.

That looks incredible Lothar. You don't waste much time when you start building do you?
Hae watched several of the video's on rcmovie.de and all your models seem to fly very well.
-
Fantastic Lothar! :clap: :clap:
Looks brilliant and flies great too by the looks of it!
-
Lothar, which do you prefer more,…. building these planes or flying them? (I think you are a man in love with wood.)
The new bigger model seems to land better than the smaller one that I saw you fly at the flying field in Ireland. Of course, it could be that your piloting skills have improved since then. :lol:
Just changing the topic slightly Lothar. I remember you asking, while you were in Ireland, why nobody uses a bungee (elastic) to launch their models when at the slope.
I’ve come to the conclusion that it’s just tradition to hand launch.
The largest model I’ve got is 2.6mtr wingspan, and for that it’s just as easy to hand launch off the slope.(When there is plenty of wind I know it’s going to fly.) But at the Glide-In earlier this month there were some big models and nobody used a bungee, they all hand launched. Strange isn’t it? :roll:
Just as a foot note; It hasn’t rained in this part of Ireland for over two weeks! And the temperature is warm. We are told that it‘s not likely to rain for at least another week………can you believe that? :D

No, that's unbelievable Keith :mrgreen:
Well, my skills in Flying are growing a little bit. Also it's easyer to fly the big one, than the smaller one. Especially the landing is better with the big one, because it has speedbrakes. Just more comfort for the pilot.
And actually i am in love with wood. Wasting time was never my cup of tea. I try to work as efficient as possible. There's only one life as modeller I have :wink: So I don't waste my time. As we say in Germany: "Good Tools are half of the job". In the last 2,5 years I made about 8 or 9 wooden planes and my skills are now not to bad.
and Bill... every Horten goes well, if the plane is good engeneered. The aerodynamics are a bit complicated, because all functions are made with one wing.
Best Regards to the sunny Ireland

Hi Lothar
What a fine looking model, I wish I could build as fast as you Lothar, well done.
