Quark 2M - Back to cutting innocent trees!

<< < (93/113) > >>

Nhalyn:
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.  8) (that's a project... :-[ :-X)

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

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.

John.
