Quark 2M - Back to cutting innocent trees!

[Nhalyn]

Hi guys !

Next step...

I've put 5x5mm balsa stick all around the canopy for stiffness purpose (as servo tray don't touch the sidewalls). This leads to modification of frame C3, but not on frame C2.
Also prepared the elevator rod (not finished servo side) : it will be carbon rod in this all wood glider... 

Then, assembly on the fuse ! Nice curve !    :-*

  Nice build Jean Mi!
You have 2 months to finish it!

Good job

Hi all,

this is my first post here. I am also planning to build a quark. But I have one question... (I am not so an experienced builder..).
Which is the best method to glue the carbon tubes in the wing to the wing ribs? Cynao? Or 90 minutes epoxy?

Thanks!

Marco

I used cyno to secure them in place and then some epoxy to add some more strength.

Hello Marco ! Welcome...

For Carbon I use Cyano with great success. Just put a little grind with sand paper on the areas to be glued and it's strong.

Just put parts in the right place and use very fluid cyano to add glue.

Last news... Becoming better, fuse nearly complete. Color is comming ! 

Seems I need a pair of wing and a stabilizer...

Hi, thanks to both of you! I look forward to complete the build in the next weekend, and the I will post pics!

Hi Marco,

Welcome to the forum
Enjoy your Quak build, and do not hesitate to share photos or ask anything

Like the others, I used Cyano for my tubes. Then, a second pass, outside, with Cyano accelerator. The cyano becomes hard and really seal the tube to the ribs. Not sure if this is actually "working" but I felt better after I did it It's all in my head

@ Nhalyn: Looks very good!!
Keep up the great work! April is coming soon!

And finally, the Quark in the snow! Photos received  from Sweden.. Or Norway, I can't remember!

Hi Fred, thanks! I will share pics for sure. Promise.

I am waiting for the balsa sheets to start the wing build. I think I will try Cyano+activator at first: however the fit between few ribs and the tube is slightly loose. so I may use epoxy as well where needed (I have a new UHU plus 90 minutes box). Or do you think Cyano+activator can be just fine also for loose fit? I never built a wing with a carbon tube spar so far..

Thanks and see you soon ,

Hi !
If ribs are just sightly loose, Cyano + Accelerator will be fine, as this tighten the cyano "as it is", so give it volume.

I prefer cyano, as I fell it will live longer and better than quick époxy.

April is comming quick, and I done nothing since last sunday ! Grrrrr... But I will have time for the next two days and week-end. Goal is to have fuse ready for cover on friday.  (that's a project... )

Quark in snow is pretty cool, in all senses of words !
But why have covered it in white ? Camouflage ? 

[Nhalyn]

Hello all !

Lets have a finished rudder... 

Hummmm... Fred, I think there is a mistake in the cutting file of the quark : a missing hole in the rib number N0 ! 

[DannyChapman]

My Quark build is coming along pretty well (though I'll post some photos below so you can tell me what I've done wrong!).

Two pressing questions as I'm on the tail and fin:

1. Do people glue the tail(s) onto the axle and incidence rod through the bellcrank? My inclination would be to keep the tail removable, if only for ease of repairing (not that I intend that to be necessary!) and travelling, but if so, what's the best way to keep it in place.

2. After dry-mounting the fin, and cutting through the stringers, I realised that the fin and rudder will be supported mainly by the tail end of the fuselage - behind the incidence pin slot. This isn't as rigid as I would like because of that slot, and the lower part of the fin (that straddles the upper part of the slot) has got a fair amount of give in it so isn't a lot of help. Should I be worried about this? I'm somewhat inclined to sheet the fin with 1mm balsa, cross-grained with the base of the fin, but don't want to add any more weight than necessary.

Hi Danny,
             Looking good. For the fin I cut a slot down the trailing edge and glued in a carbon rod that extends through the fuselage into a balsa block glued to the bottom fuse sheeting.
