Quark 2M - Back to cutting innocent trees!

[Richard Boyd]

Hi George, really nice bit of workmanship, keep us posted on your build

Either carbon or alloy is good !

[GeorgeB]

I use carbon for my quark

thanks Mario, I'll use carbon too.
Do you have some video of your Quark flying over ocean?

thank you Richard, by the way I bought tubes and rod and they match together without any problem :shock:  Anyway thanks again you offered yours :clap:
And yes I'll post my progress :wink:

Hi George,

Really looking good!  :clap:
Yeah, I used aluminium (I use scraps of stuff I have  :wink: ), but carbone will do it fine too  

Very good build so far  :clap:  :clap:

Thanks Fred, I spend almost my every free time to build Quark, but still a lot of work in front of me

sorry , no video for the moment

Hello,
I plan to start my Quark 2M build this weekend becasue i want to try something new on the slope...

The only thing i am not sure about is which servos to choose. The Ailerons are really huge (could be a problem for the standard HS81 with higher speeds?) and as this will be my first aerobat I don't know exactly what is more important - speed, torque, precision...? For my slope racers I never had to think about anything, the slim wing servos like HS125 were the only ones that would fit in.

So which servos do you use in your slope aerobats and what would you recommend?

Thank you

Hi Miki,

Welcome to the forum  

For servos, everything is important (speed, torque etc), but maybe one of the most important, is the servo capability to come back to the exact neutral position each time (can't remember the English word for that (and I will not try in German!   ))

In my case, I use 2 standard servos for the Elevator / Rudder, and 2 MG14 at the ailerons, everything hooked up to a 6v battery for speed and added torque.
And this is working just fine for me (went agricultural and on the cheap!   ), but maybe others will jump in and tells you what work for them  

In the mean time, don't hesitate if you have any questions.

Fred,

Any news when the short kit for the Quark will be available?

Alistair

[Fred]

Hey Alistair,

Yep, files are ready, and they will be tested on Saturday!
If all goes well, they should be online next week hopefully! (That's if I receive the boxes for the kits on Monday, fingers crossed!)

The Quark should be even lighter! (most of the plywood for the wing etc, replaced by Balsa, lightning holes in the fuselage etc) to make it even better!  

[alibodin]

Patiently waiting for kit to be available.

Is there a list of parts required to complete the kit?

Alistair

[Richard Boyd]

Hi Alistair, this is what I roughly required to finish my short kit of the Quark 2m

3off 10mmo/d,8mm i/d carbon tubing wing

1off 8mm o/d carbon or alloy tube for wing joiner(needs to be snug fit with the above)

1off 4mmo/dx 3mm i/d  tube for elevator

1off 3mm solid carbon for elevator joiner

Closed loop wire for rudder aprox 2.5m should be enough, plus use loop adjusters for fine tuning.

Elevator push rod, I used balsa square with light fiber glass to make ridjet and piano wire z bends to servo.

Control horns x 4  good quality

Servos, any good standard servo for elevator+ rudder (6v servos is good)
for wing servo you are restricted  to slimmer servo , 14mm deep servo should be snug fit as far as I remember.

2 x 700mm servo extension leads for aileron servos

The rest is just general items like covering etc. and radio gear of your choice.

Thank you very much for the information.

I will be building mine with balsa ribs too (only the 3 inner ribs will be plywood for more strenght around the wing joiner area).I can't wait building with balsa again, thats what i really missed when flying and repairing molded models....

And now i'm off to the hobby shop!

[Fred]

Hi Miki,

No problem at all, and don't hesitate if you have any questions!  

And most important, have fun with the build! You'll see, it is quick and easy to build

Hi again,
i already started the fuse - build is really simple compared to some other projects i built. The only thing i was thinking about was top and bottom sheeting of the fuse and balsa grain direction. Will the construction be more rigid with cross or straight grain balsa? In the curved front sections cross grain would also be much easier to bend...
