Thank you all

Look better on photos actually!
Hate this plastic covering transparent thing! :!:
Next one, Ferrari red Vinyl!

No flying this week end (family stuff), but hopefully, weather will be good next week end, either in Dublin, or up North (have to fly in NI before the end of year! And good occasion to get a "group" photo!

)

Hello;
I have downloaded the plans and taped them together, but one thing i don't understand;
how are the wings attached?
By means of an 8 mm carbontube sliding in the 10 mm main spars?
Same with the alevators.

Is there a shortkit availeble?

thnx; Nico

Hi Nico,

Welcome to the forum

To answer your question, yes, the wings are attached to the fuselage with the carbone rod (8mm), sliding in the carbone tubes (10mm).
The 8mm carbone rods are the wing joiners.

Then, as you can see on the plan, 2 hooks will held the wings to the fuselage (you can use rubberbands).

Hope this helps, but let me know if you need more details

Fred

Oh, forgot, short kit not yet available, but should be soon!

thnx Fred, for the fast response.
The hooks, i had figured out.
Is the allevator held in place in the same manner , that is, with 2mm rods in the 4 mm tubes?
Please keep me informed in concern of the shortkit

thnx; Nico

No problem at all,

Yep, same for the elevator

Well, the Quark continue its travel around the World, this time in South America

Received this morning a mail from Brasil where the Quark will be flown during a aerobatic contest in the biggest slope event in Brasil

Brilliant news Fred

I have half a wing completed all but the aileron,
Tonite I am free and intend to do a little more work on my Quark.
We have big winds today and I wish I had of had my Quark ready to fly,
Good luck to the Brazil pilot :clap:

Richard

Quark wing half almost complete, at last :shock:

I have the lovely 45 throws for ailerons,

Nice work Richard. :clap: :clap:

Was that the 2nd, 3rd or 4th shipment of carbon :wink: :twisted:

Alright, following last week end flights, I made a few changes on the Quark to make it even better! Well, that's the plan anyway! :mrgreen:

First, and most important modification, is the elevator. As it is, it is working fine, but I found it not "sharp" enough, and compared to all the other controls, that felt a bit like a let down!

So now, the elevator have a "real" profile, and that should also shift a few grams at the back, and that's a lot at the front!
I'll start mine later, but here are the plans for the ones who wants to give it a go :

http://www.gliderireland.net/files/quark/Quark2Melevatormod-Plan.PDF
http://www.gliderireland.net/files/quark/Quark2Melevatormod-RIBS.PDF

It's a direct replacement of the one you already have, and should not take more than a few hours to make

While I was at it, I have changed the way ailerons are built. No more sanding!

And finally, I have added 5cm to the nose to help with the CG. All that should shift around 300grs off the glider.

Anyway, thanks to Keith, I have 2 minutes of raw footage of the first launch of my Quark

Roll after the first 5 seconds, no trim adjustement, a real pleasure to fly!
The only changes I made at the slope was to remove my expo from the elevator, that helped a lot in the sharpness division.
CG is as per JP, and on the back, only a very slight push is needed. I'll move my CofG back a bit for the next flights.

All in all, very very happy with this glider, love it in fact! Had a few reports from other builders, and all the same, good machine!

Ok, next? Well the plug for the original Quark is moving forward, and I hope to have the first fuselage done sometimes this summer
