No, It was a bit gusty and I was alone. I didn't want risk a self launch in those winds. Flew my spitfire and that was pretty hairy.
John.

Yeah, Sunday's conditions were a bit on the extreme side for the Quark!

You don't have my number to text me?  :?:
Maybe this week end? I might be free

Hi all,
      Maidened my Quark today,':D' what a beautiful flyer. She went straight off only needing a few clicks of downtrim to sort her out. I was really impressed with the efficiency of the wing section so much so that I had some difficulty in getting her down. It was quite windy 25 knots, after about 6 passes attempting to put her down Jim commented that "the wind will drop at about 7pm".':shock:' I think that I might have too much reflex on the ailerons and maybe will programme it to be adjustable during flight. Best glider I've ever flew and looking forward to flying it some more.
John.

Congratulations again on the first flight of your Quark John!  :clap:

Glad you like it

Hi all,

Greetings from Australia
Fred - I love the look of the Quark and I can't wait to get it flying. Also a big thank you for making the plans available.

I am about to start building my quark over the Christmas break and I am planning to make the wing with flaps. The landing site at my local slope is very tight so the slower the better.

I would like to know what percent of span you would recommend for the flaps?

At present the my quark is just a lot of balsa but I'll include some photos as I get the build underway.

I hope everyone has a very Merry Christmas.

Cheers,
Colin.

Hi Colin,

Welcome to the forum, and good to see you here  
The original Quark plan have flaps actually, but decided not to do them.
On the plan, flaps are roughly 50% of the ailerons.
With quadros etc etc, that should gives you a nice setup.

Mind you, flaps are not essential for landing, with ailerons down, and the low wing loading, that thing can land pretty much anywhere  

Have fun with the build, and don't hesitate to let me know if you have any questions. (and please, post photos!     )

Looking good Fabio!  :clap:
I like the white trims on the wings. Are they painted?  :?:

[fabio1963]

yes Fred,
 totally painted, I used 3m strips for trims and frisket for lettering, airbrush for skull.
yesterday after a stout landing my quark suffered some damages in the fuselage near the bayonet. exactly around the first ribs on the fuselage, both  disconnected...
I repaired it applying some thin plywood poplar inside the fuselage, but I suggest to reinforce this part of our quark.sorry for my english

bye

Looking good Fabio!  :clap:

Hi Fabio,

No worries for your English (very good), you should hear my Italian!    :oops:

Sorry to hear about your crash! If I understand, the fuselage broke at the wing joiner right?
Is the plywood rib on the fuselage that broke?  :?:  (If you have a photo, I will be happy to have a look at a modification here, maybe by adding another rib / support inside the fuselage  :?: )

Anyway, you are way better at painting than me! You have skills!  :clap:   I only manage to use stickers, everything else usually end up in a disaster!  :oops:  :oops:

Hi All
Just received my Quark kit , as I'm an inexperienced balsa basher  I have a few question I'm hoping you can help with .

1. Whats best for the wing spar's Stika spruce or cyparis ?
2. The wing ribs have a 5X5mm notch in the front is this for the leading edge  or does the leading go on top of that ?
3. Presumably the leading edge should be of fairly hard material, would stika spruce be a good thing to use ?
4. Can you recommend some reasonably priced servos ?
 
All comments/advice welcome .
Thanks in advance .

Nick .

[Fred]

Hey Nick,

Welcome to the forum, and apologies for the late reply  :oops:

In order

1>For the spars, I kept it simple, and used Pine I started another wing with balsa spars, and works well so far, but if you have access to both materials, I would take Stika spruce then, but don't worry too much about that
2>The 5x5 notches are what we call a "false" Leading Edge. The real LE will be glued into it. This add stiffness and support, can be made of 5x5 balsa or pine (in my case)
3> In my case, they are balsa, because easier to sand in shape, and that is pretty solid with the 5x5mm pine backing. You also have to try to keep it as light as you can
4> For servos, in my Quark, I used the Hobbyking stuff. I used the MG14 for the ailerons, and standard size servos for the Rudder/Elevator, but the range is huge! Try to get servos with metal gears, standard size for the rudder/elevator if possible, but you can of course go smaller. Mini size for the ailerons, like I did with the MG14, but you can also use the HS81 or equivalent of course


Hope this helps, and that is clear, but let us know if not, happy to help
And keep us posted on the build

Flew the Quark this evening in really light lift, once I switched in the rates for aileron and elevator she was great fun to fly in the marginal conditions. Managed a few loops and rolls. God practice to fly smoothly so as not to loose too much height.

Nice one Alistair!  :clap:
I can't remember, but do you have any photos of your Quark?  :?:

[alibodin]

Yes I think  I sent you some and they are on Island Models Website.
