Quark 2M - Back to cutting innocent trees!
joe:
Wow. Thats very cool Fred.
Richard Boyd:
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
Richard Boyd:
Quark wing half almost complete, at last :shock:
I have the lovely 45 throws for ailerons,
billscottni:
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 :

It's a direct replacement of the one you already have, and should not take more than a few hours to make :D
While I was at it, I have changed the way ailerons are built. No more sanding! :D 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 :D 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 :D
